GENERAL SAFETY REQUIREMENTS
This manual contains specific precautionary statements relative to worker safety in
appropriate sections.To avoid dangerous situations we give you the following advice:
Refers to special information on how to use the dust collector most
efficiently.
Refers to special information directed towards preventing damage.
Refers to special information designed to prevent injury or extensive
damage.
The collector should be stored as supplied. Remove packaging for installation
only.
For the purposes of storage:
• Collector with specification for inside use = IP50
• Collector with specification for outside use = IP54
The dust collector has been built in accordance with state-of-the-art standards
and recognised safety rules. Nevertheless if not handled carefully it may put
people at risk and also cause damage.
The dust collector should be used only when it is in technically perfect
condition, in accordance with its designated use and the instructions set out
in the operation manual. Any functional disorders, especially those affecting
safety, should therefore be rectified immediately.
Ensure proper training is given to operators before start-up. The dust collector
is designed exclusively for use within the scope of delivery, and in accordance
with drawing(s) and the specification sheet.
Do not put lit cigarettes or any burning object into the hood or ducting of any
dust collection system.
Regular maintenance is important for a good performance ofyour dust collector.
A prudent user of Donaldson Torit equipment should consult and comply with
all relevant Fire Codes and/or other appropriate codes when determining the
location and operation of dust collection equipment.
A hand-operated supply disconnecting device is necessary for each incoming
electrical supply in accordance with EN 60204-1.
To prevent accidents the access to the fan impellor must not be possible during
operation. Refer to EN 294.
Disconnect all power before servicing. All electrical work must be done by a
qualified electrician according to local codes.
All exposed conductive parts of the electrical equipment and the dust collector
shall be connected to the protective bonding circuit (refer to EN 60204-1).

Installation, Operation and Maintenance manual

Downflo®Evolution
Shutoff and bleed-off compressed air supply before doing any service work.
In each individual case vent design, vent ducts and pressure resistant design
are worked out by DonaldsonTorit for the specific products, circumstances and
environment, and should never be altered unless Donaldson Torit has given
explicit admission.
All electrical equipment should be dust explosion proof according to the zoning
and surface temperature limitations of the equipment.
The dust collector cannot be used in a potentially explosive atmosphere
(according to ATEX directive 2014/34/EU), unless stated otherwise on the
nameplate of the unit and the scope of delivery.
When handling explosive or flammable materials, the collector should be
located so as to avoid external heat source - e.g. from nearby processes or
extreme direct sunlight.
The user of the dust collector is responsible for disposal of any dust generated
by the process, in accordance with local regulations.
The dust collector will not prevent explosions;
The main cause of dust explosions in dust collectors are hot and glowing
particles which are formed in the process upstream - these are conveyed
into the collector and get imbedded on the filter medium. There they either
extinguish or develop into a smoldering or even open fire, in the end leading
to an explosion.
A prudent user of Donaldson Torit dust collectors should:
• Take every possible precaution to prevent a fire or explosion from occurring.
• Consult with their insurance carrier or local authorities regarding the hazardous
nature of dust produced.
• If dust is classified poisonous, corrosive or irritant as per ‘Gef-Stoff V’, an
explosion venting system should not be used. The dust collector will then have
to be protected from explosion by other methods (consult your Donaldson Torit
representative).
• Sizing of the bursting opening + reinforcement of the dust collector are dependent
on the dust collector type, the dust explosiveness (Kst value or St classification)
and on the blow- off channel length + size when required.
• Consult and comply with national and local codes or bulletins (VDI 3674) when
determining location and operation of Donaldson Torit dust collectors.
• Use only authorised replacement parts supplied by Donaldson Torit.
• Unless otherwise specified, DO NOT exceed negative operating pressure as
specified by technical data, DO NOT use on positive pressure systems.
• Insure that the operating temperature of the dust collector does not exceed 120° C.
• Do not locate the bursting panel assembly where people are exposed to the
bursting panel itself or to the area above or in front of the bursting panel as they
may be injured by the escaping pressure, fire, noise, chemicals and/or fragmenting
particles. The location of the bursting panel must be such that the discharge
cannot be the ignition source of secondary explosions. Interfacing equipment
and/or machinery must also be protected.
• Refer to guidelines VDI 3673.

Gas explosion proof equipment is not necessary but may be used when
appropriate.
Maintenance and explosion safety
a. Introduction
The collection systems are designed and installed by Donaldson Torit engineers
applying the most appropriate safety measures based upon state of the art knowledge
and technology.
It’s safety is based upon two main objectives:
• Prevent ignition sources that might be caused by the collection system itself, as
far as it is practically possible, by using appropriate dust explosion proof electrical
equipment, antistatic filter cartridges, conductive construction materials and ducts
which are all bonded and grounded.
• Confine an actual explosion caused by an ignition source coming from the
process or induced by the user (hot work collection system) in such a way that
no hazardous effects occur:
• to plant personnel
• to the location in which the dust collector is installed
• to equipment connected to the dust collector
If the dust collector’s original design or the actual process is changed without
implementing the changes in the safety design of the collection system, it’s
safety can be jeopardised. However, poor and/or incorrect maintenance can
also jeopardise the safety of the system.
b. Hazards due to change of dust collector design
The housing is modified; a larger volume, weaker housing (e.g. by installing
extra inlets or manholes).
The vent area is reduced; e.g. by obstructing the vent by ducts or other
obstacles.
The vent panel type is changed; e.g. by using a panel that has a higher opening
pressure or larger inertia.
The vent duct is modified; longer, smaller cross section, bends, obstacles or
extra covering on the outlet.
The vent location is altered; e.g. instead of top venting now side venting is
applied- besides possibly obstructing the vent process, reaction forces may
cause the collector to tumble over.
If applicable, the explosion suppression system is modified.
In these cases the safety measures may not be able to protect sufficiently and
the explosion may destroy the housing and or the vent duct causing hazards
around the dust collector. In particular when the dust collector is located inside
the hazards are eminent.
The rotary valve is taken out or exchanged by a non explosion proof type. Or
the explosion resistant receiver bin is exchanged by a non appropriate type.
This may lead to flames, or worse, a fireball emerging from the hopper.

Installation, Operation and Maintenance manual
7
Downflo®Evolution
The use of plastic bags in the receiver bin under the hopper is not recommended
because sometimes, due to very high electrostatic charges, hazardous
discharges may occur.
c. Hazards due to relocation of the dust collector
By relocating the dust collector from outside to inside you should be aware
that the explosion now is vented inside a room, which is not acceptable, due
to the very hazardous flame jets and fire balls.
Also, relocating outside may be hazardous when the explosion vent points
into a direction where people may get hurt or property may be damaged.
d. Hazards due to change in process or product
By changing the process, the amount of product, process temperatures and,
most importantly, product ranges may alter. If the products explode more
violently than initially foreseen the explosion may damage or destroy the dust
collector.
e. Hazards due to poor or lack of maintenance
The wrong filter cartridges are installed; non antistatic type may lead to ignition
in the dust collector.
The filter cartridge porthole or another part of the housing (access cover) is
not fixed correctly and may tear up during an explosion causing a flame jet or
fireball.
Retrofitting metal ducts by non-conductive plastic hoses, plastic or flexile ducts
may lead to hazardous electrostatic discharges.
Failing of bonding and grounding of metal parts and ducts (resistance between
metal parts preferably should be less than 100 Ohms).
Painting of the inside with high resistant coating that may result in hazardous
electrostatic discharges.
Welding, cutting etc. (all hot work activities) on an operating or not thoroughly
cleaned not operating dust collector will result in strong ignition sources and
explosions.
Painting of explosion vents may result in higher opening pressures: collapse
of the housing.
If abrasive products are used, in time this may result in thinner walls of ducting
and dust collector housing, thus reducing the strength of the equipment and
it’s explosion resistant properties.
f. Hazards due to wrong actions
Opening of the dust collector during operation: loss of containment.
Vent surrounding: if used as a storage area or frequented by personnel: a
vented explosion will cause damage to stored goods and hurt or kill personnel.

Installation, Operation and Maintenance manual

Downflo®Evolution
g. Do’s and don’ts
Based upon several hazards a list of do’s and don’ts is given.
Perform a regular maintenance by disposing the dust in a regular fashion and
inspecting the cleaning mechanism on a regular basis at least once a month.
Return the installation in its original state after maintenance (fixing, closing
and bonding and grounding).
Check the grounding and bonding at least once a year.
The housing of the dust collector should never be changed or painted on the
inside with a non-conducting coating.
Vents should never be blocked or painted.
Use the original bursting panel types only.
Do not alter the vent area or vent location.
Vent ducts should never be altered.
Do not tamper with explosion protection systems such as explosion
suppression and explosion barriers as quick acting valve.
Use original equipment as filter cartridges, electrical equipment, rotary valves
etc..
Do not use non-conductive plastic hoses and pipes.
Prevent goods and forbid personnel to be near such a vent.
Never open the dust collector during operation.
After emptying the receiver bin, fix it as in the original state.
Keep the working place clean.
For any changes in the dust collector, safety system, process, product or dust
collector location consult the manufacturer.
h. Applications having a risk of sparks and fires
1. Good Housekeeping
Accumulation of potentially combustible dust, for example dust layers is
considered a potential ignition source. Failure to keep the dust collector
clean and empty the hopper / dust bins regularly will increase the risk of fires
and/or explosions.
2. EU Directive 99/92/EC.
A reinforced and/or vented dust collector must be used when handling dusts
that have the potential to form an explosive atmosphere. If a non-reinforced
and/or non vented dust collected is used on these applications then the end
user must ensure an equivalent, secure, and fool proof basis of safety, which
must be clearly documented in the end users Explosion Protection Document
in line with Article 8 of EU Directive 99/92/EC.
3. Self Heating Materials
Please note that some materials have the potential to self generate heat and
hence to become an ignition source, that could result in a fire and / or an
explosion. For this reason ferrous and non-ferrous materials should not be
extracted in to the same dust collector, as when combined they can create
a violent thermite reaction that would ignite a fire and/or explosion.

Installation, Operation and Maintenance manual
9
Downflo®Evolution
4. Applications having a risk of sparks and fires
Where sparks are generated by the process, this must be considered as a
potential ignition source which increases the risk of a fire or explosion. The
filter can be supplied with an optional spark trap to help reduce the frequency
of spark ignition and should be regarded as part of a risk reducing strategy. The
spark trap is not an extinguishment system and should never be relied upon to
achieve spark eradication in processes where suppression requirements are
absolute. The spark trap does not guarantee complete elimination of sparks
and does not preclude the possibility of fire or explosion. Therefore, system
redundancy and complementary measures should be taken in conjunction
with the spark trap to further reduce the risk of fire and explosion from sparks
in applications where there is potential for catastrophic combustion.
On these types of applications the enduser should carry out regular good
housekeeping, such as:
a. Periodically check for dust fall out in ducting and remove.
b. Pulse down off line regularly to minimise retention of dust cake on filter
cartridges.
c. Empty dust bins frequently.
Other risk reducing strategies could include
a. Inject with an inert material.
b. Consider additional spark detection and fire suppression equipment.

INTRODUCTION
Product information
The dust collector is used for the collection of airborne dust and particulate.Whether
in response to the problem of air pollution, or as part of a manufacturing process, the
dust collector provides highly efficient, continuous, on-line dust collection.
The filter cartridges are the heart of the dust collector. These filter cartridges help
ensure that only cleaned air is returned to the plant environment.
The reinforced dust collector can collect explosive dust without putting people at risk
and with a minimum of structural damage as a result of an explosion, assuming that all
safety guidelines in this manual are followed. For each reinforced model the maximum
Kst value for an inside as well as an outside installation is defined (see spec sheet).
Be sure that the explosive (Kst value) of your dust is always below the maximum Kst
value defined for your dust collector type.
Technical and field support are available from your local Donaldson Torit representative
or distributors to answer your questions.
Function
During operation, contaminated air enters the dust collector through the dirty air inlet
area and passes through the filter cartridges.
Dust is collected on the outside surface of the filter cartridges.
The filtered air flows through the centre of the filter cartridges into the clean air
chamber, where it exits through the clean air outlet and can be recirculated into the
environment.
To ensure the optimal performance of your dust collector it is necessary that the filter
cartridges are cleaned automatically and sequentially.
During the cleaning sequence, the timer energizes a solenoid valve, causing the
corresponding diaphragm valve to send a pulse of compressed air through the filter
cartridges (from the inside outward), removing the collected dust from the outside
surfaces of the filter cartridges.
The dust falls through the hopper into the dust disposal system.

Protection of the dust collector against dust explosion
The reinforced dust collectors are protected against dust explosions both by preventive
and by constructional measures.
Preventive measures are to prevent ignition sources in the delivered installations:
• Electrical equipment is dust explosion proof: IP6X for zone 20 and IP5X for zone
21 plus equipment surface temperature limitation (depends upon the product).
Gas explosion proof equipment is not necessary but may also be applied when
appropriate.
• If necessary, the filter cartridges are antistatic. (see scope of delivery).
• All conducting parts are grounded or bonded and connected to ground.
• Internal coatings do not cause static hazards etc.
However, these measures do not prevent ignition sources due to the process or
outside influences. Means to eliminate ignition sources from entering the dust
collector are a preseparator, a spark trap or a spark detection with extinguishing
system. Supply of these items are optional and will depend upon the typical process
parameters (see scope of delivery).
So-called constructional or post-operative measures are measures to limit the potential
explosion effects in case an explosion still takes place in spite of the preventive
measures.
The measures taken on the reinforced dust collector are:
• Explosion venting in combination with explosion resistant design for the expected
reduced overpressure and compartimentation
This is a typical mean against the effects of explosions. Of course against fire hazards
alone the dust collector can be delivered with optional sprinkler systems or other
extinguishing systems.

Installation, Operation and Maintenance manual
12
Downflo®Evolution
By venting the explosion to the outside in a safe direction (outside), the pressure
inside the dust collector is limited such that it will not collapse. The vent area is
designed using:
• VDI 3673. Pressure Venting of Dust Explosions, VDI-Kommmision Reinhaltung
der Luft, July 1995.
• NFPA 68. Guide for Venting of Deflagrations, 1994 Edition.
• EN 14491. Dust explosion venting protective systems, March 2006.
• IChemE. Dust explosion prevention and protection, 2002.
The explosion panels are certified and provided with a device to detect its actual
opening up.This device should be used to stop the plant automatically by interlocking
and can be used to activate a sprinkler system to extinguish a fire following the
explosion.
By using vent ducts in case of indoor installation, the explosion is lead to the outside
and into a safe direction. Vent ducts, however, will increase the expected reduced
explosion pressure considerably. To prevent that the expected reduced explosion
pressure exceeds the design strength of your Donaldson Torit dust collector, the
maximum Kst value of your dust to be collected has to be considerably lower in case
of using vent ducts .
There also should be taken into account that, due to the venting explosion, the dust
collector is subjected to a reaction force.
Standard DonaldsonTorit dust collectors are vented vertically and the reaction forces
will be directed downwards into the foundation of the dust collector: this causes no
hazards.
However, when the dust collector is side vented, the reaction forces also are directed
horizontally and may push the dust collector over if not secured well.Therefore in case
of horizontal vents the Donaldson Torit dust collectors should be specially secured.
See figure 5: Typical foundation anchor, page 17.
In case of side venting, the dust collector will have to be adequately supported
in order to cope with horizontal recoil forces. See figure 5: Typical foundation
anchor, page 17.
To prevent that the explosion runs back to connected equipment, a back-flap valve
or other explosion barriers should be installed.
To prevent propagation of fire, burning products or explosion from the hopper to the
outside or process, through the hopper outlet, either an explosion proof rotary valve
should be installed that automatically stops at explosion detection or an explosion
proof reception bin or other explosion proof dust discharge systems.

Installation, Operation and Maintenance manual

Downflo®Evolution
PRIOR TO INSTALLATION
Location
The dust collector should be located with consideration for:
• emptying the dust disposal (see figure 1, page 8)
• shortest runs of inlet and outlet ductwork
• radius bends on elbows as big as possible
• easy access to electrical and compressed air connections
• convenience of maintenance
Consult the technical specification sheet and drawings for the dust collector
weight and dimensions.
For calculating for foundation or supporting structure consider the following factors:
• the weight of the dust collector
• the material being collected
• all auxiliary equipment
• live loads
• for outdoor installation: snow and wind loads
Required tools and equipment
• crane/fork lift
• slings/clevis pins and adequate lifting equipment
• standard tools (screwdrivers, wrenches, etc.)
• drill
• pipe sealant
Delivery and inspection
The dust collector is normally shipped by truck and should be checked for any
damage that may have occurred during shipping.
Note that the bursting panel is always shipped mounted upside-down on the dust
collector top flange to prevent any damage.
On top of the bursting panel a galvanised plate is positioned to protect the panel from
damage during transportation.The bursting panel and galvanised plate are secured in
place with 4 bolts. The other bolts, nuts and washers and the burst indicator switch
are delivered together with the dust collector.
Compare the parts received against the packing list. If there is damage or parts
missing, notify the delivery company and your local Donaldson Torit representative.
Parts shipped loose with the delivery (depending on your order):
• dust disposal system • platform • legs and bracings
• transition pieces • spare parts • control box
• fan set • anchor bolts • damper pack
• fan box • hardware/sealant • bursting panel
• silencer • hopper • burst indicator set

Installation, Operation and Maintenance manual

Downflo®Evolution
INSTALLATION
All external equipment connected to the inlet, outlet or discharge
(e.g. ducting, rotary valve) should be correctly sealed. This can be achieved
by applying a continuous 5 mm bead of sealing compound to the mounting
surface, along each side of the hole pattern. For non-Donaldson Torit
equipment please also check supplier’s IOM manual for any specific
requirements.
Unloading and transport to location
Before unloading, remove all packing and strapping.
A crane is recommended for the unloading, transport and installation of the dust
collector.
Connect lifting sling to the lifting lugs with clevis pins and distribute loads
equally. Use spreader bar if necessary.
In case of inside installation, a vented dust collector will be provided with a special roof
flange. This allows the mounting of a blow off channel (max 3m) around the bursting
panel. Channel will divert escaping pressure outside the premises.
Ensure blow off channel is mounted on roof flange with the pre-drilled hole on the
same side as the sensor brackets of the bursting panel. This hole is used to pass the
cable of the sensor through the blow off channel.

Hopper & leg installation
(see figure ‘Hopper & Leg Installation’)
There are three types of hoppers for your dust collector:
1. a single module wide which spans two portholes
2. a single module wide which spans three portholes
3. a double module wide which spans four portholes
Each of these styles transition to a single outlet opening. All of the leg arrangements
are shown in figure 6, ‘Leg positioning’. The position of the legs, cross bracing and
hoppers for each dust collector size is shown.
1. Stand the hopper(s) up with the disposal end up (hopper outlet).
2. Use drift pins to align the holes in the hopper gussets and legs, and attach the legs
with the bolts, washers and nuts. Do not tighten hardware at this time!
3. Use drift pins to align the holes in the cross bracing on the rear side of the leg set.
4. Recheck the position of the legs and cross bracing against figures ‘Leg Bolting
Details’ and ‘Standard Leg Packs’ and the drawing.
5. Join hoppers together at the hopper gussets using bolts, washers and nuts. Do
not tighten hardware at this time!
6. Flip over the now-assembled hopper/leg pack assembly so that it is standing on
its legs (hopper outlet pointing down). This step may require a crane. Another
option is to divide the hopper/leg pack assembly into smaller sections to flip over.
Make sure to join hopper together after flipping over.
7. Lift the assembled collector onto the foundation. Fasten each footplate of the
leg anchor bolts with flat washers, lock washers and nuts. Do not tighten
hardware at this time! (Depending on the type of anchor bolts, anchor bolts
can be mounted afterwards).

Field joining installation
(See figure ‘Field Joining Installation’)
The dust collector is a modular unit that may require field joining. The field joint may
be a result of truck capacity, crane capacity or specific customer requirement.
A detailed drawing of how to join your dust collector has been shipped with your dust
collector. Most of the joining hardware is on the inside of the collector. A stepladder
will be helpful in assembling the flanges near the top of the collector. Both the dirty
air and the clean air chambers will have to be accessed during joining.
Two cranes are required.
Read all instructions for assembly.
Leave one hopper off the collector on either side to the joint.
The yokes, filter, cartridge baffles and outlet covers have been left off the joint
side.
Follow all safety precautions when installing your dust collector.
1. Remove the protective shipping cover from each module.
2. Remove one inspection cover on the clean chamber.
3. Apply sealant to one side of the joint. Follow the sealant pattern exactly as it is
shown in Figure ‘Field Joining Installation’.
4. Lift both units with cranes into position for joining. Align the bolt holes in the
flanges with drift pins. Bolt the joint together with the bolts, washers and nuts.
Do not tighten hardware.

joint side of each module as shown in Detail A.
3. Remove outlet cover from the bottom of the clean-air plenum and set aside.
4. Apply a generous amount of sealant to one module to create an airtight seal
between the clean- and dirty-air plenums as shown in Detail B.
5. Lift both modules into position using two cranes.
6. Use drift pins to align the bolt holes in the mating flanges.
