Introduction
This present manual refers to the Maxiflo-VC
dust collector equipped with an air pulse
cleaning system. It includes important
information concerning the installation, usage
and maintenance of your collector. Read this
manual thoroughly and apply the directives and
procedures. Staff and personnel using the
system will have to trained on safety measures
and maintenance instructions.
Warning!
The usage of the collector or the type of dust to
be filtered may require an explosion relief
venting system. Dust collectors are not
equipped with such a device unless it was
requested when ordered. Contact A.Q.C. Inc. if
you have any doubt in regard to the usage of
your collector.
Warning: Not following directives and
procedures could cause injuries or property
damage

Introduction
The Maxiflo-VC is a cartridge dust collector
with an air pulse cleaning system which cleans
the entire surface of filtration. The down flow
type dust collector obtains high efficiency
filtration while requiring low energy
consumption. The cartridges are cleaned by
means of a sequenced pulse of compressed air
and this, one at a time.
The Maxiflo-VC dust collector is largely used in
areas where dust is a nuisance. Main
applications are for welding, buffing,
pharmaceutical operations, handling of volatile
dusts, etc.
The Maxiflo-VC may offer multiple
configurations for dust capture. Optional
equipment may include a hopper with quick
clip drum, drawer or with conveyor and rotary
valve.
Each Maxiflo-VC unit includes:
·Fully welded steel cabinet with
reinforcements.
·4 to 80 filter cartridges with specific media
for your application.
·Air deflectors to protect the cartridges from
larges debris.
·Cartridge cleaning system by air pulsation
and electronic sequencer.
·Factory prewired cleaning valves.
·Differential pressure indicator showing the
status of cartridges.
·3 steps paint finish: degreasing, prime coat
and polyurethane final coat.
The Maxiflo-VC unit is shipped assembled or in
sections for final field assembly.
Electrical connections for the cleaning system
will be executed at the job site upon the
collector final installation.

AQC Dust Collecting Systems
Normal usage
The Maxiflo-VC unit is designed to remove dust
from the air resulting from a fabrication
process. Each Maxiflo-VC dust collector is built
as per the criteria and information supplied by
the customer for a specific application and
should not serve any other application without
the approval of A.Q.C. Inc.
Warning!
Flammable or explosive dusts and
solvents present a fire or explosion hazard
within the collector. Under no
circumstances, those pollutants should be
filtered by the collector unless it has been
designed to that effect and equipped with
an explosion relief venting system or
fire extinguishing device. This is the
reason why special attention is required
with the handling or usage of dust
collecting equipment in contact with
flammable or explosive dusts and
solvents. Any burning or flammable
material such as a spark created by metal
grinding, lit cigarettes, spark, etc. should
be introduced within the collector where
it could cause a fire or explosion.

Operation
During normal operation, the Maxiflo-VC unit
vacuums dust laden air into the collector inlet.
Smaller particles are vacuumed toward the
cartridges and larger particles fall toward the
dust storage section. Dust is trapped within the
cartridge leaving clean air crossing the filter
toward the collector outlet.
Cartridge cleaning
The cleaning of the filter cartridges is
performed using a reverse air pulse technology
(see drawing # 1). A solenoid and diaphragm
valve system is aligned toward the cartridges
and the shock wave created by releasing air at
high velocity cleans the cartridges. The
cleaning cycle starts from the upper cartridges
and ends at the lower cartridges.

Installation
Inspection of goods
The Maxiflo-VC unit is shipped assembled or in
sections. Proceed with a visual inspection upon
receiving the material and check for any
apparent damage that may have occured on
freight. Generally, shipment includes the filter
cabinet and the dust storage section with
support structure. Other optional components
such as flame front exhaust duct or back draft
damper may be delivered on separate skids.
Location
1. The area where the dust collector will be
installed should be able to sustain the
weight of such along with the
accessories, ducting, blower and matter
that will be stored. The construction of a
flat and solid surface such as a concrete
slab or platform may be required.
2. Wind factor and seismic zones should be
considered before selecting the location
of the dust collector.
3. Position the dust collector in a way to
have access to the control panel, cleaning
valves, pneumatic conduits, access door
to filters and dust storage systems as
suggested in drawing # 2.
4. If the dust collector is equipped with an
explosion relief venting system, follow
guidelines for its location.

Assembly
Required tools
The following tools and equipment are required
for the assembly of the dust collector:
·Crane or lift truck
·Spreader
·Chains
·Slings
·Shackles
·Eye bolts
·Spikes
·Wrench
·Sockets
·Power drill
·Concrete drill bit
·Concrete anchors
·Bolts
·Self tapping screws.
·Caulking
Assembly
1. Prepare the area where the collector will
be installed making sure it is clear and
free of any obstacle.
2. Using eye bolts, slings and shackles, lift
the dust storage section above the
selected area and set slowly.
3. Once this section firmly set to the
ground, make sure it is level. Use anchor
bolts to keep it in place.
4. Install a ground wire to the unit.
Warning !
Apply two strips of butyl adhesive on the
dust storage section upper outline. One strip
should be applied inward of the bolt holes
and one strip outward of the bolts holes
(drawing 3).
5. Lift the filter cabinet using the lift lugs.
Using spikes, position the cabinet above
the dust storage section making sure to
align the cabinet bolt holes with the dust
storage section bolt holes.
Warning!
The use of a spreader is recommended to
avoid damages to the filter cabinet.
6. Lower the filter cabinet onto the dust
storage section and align both sections
bolt holes.
7. Attach the filter cabinet to the dust
storage section using the supplied nuts,
washers and bolts. Tighten bolts for an
adequate seal.
8. Use caulking to eliminate possible leaks.
Warning!
The use of improper lifting device
may result in injuries or damages.
Adequate lifting devices are required
and necessary precautions must be
taken when handling the equipment.

Structure assembly
Generally, the support structure is factory
assembled but because of shipping
purposes, some field assembly may be
required. The next steps must be
followed to assemble the dust collector
structure.
1. Vertically install the outer support legs.
2. Install the cross braces with the hardware
supplied as shown in drawing # 3. One is
installed inside of the legs and the other
outside of the legs. Do not tighten the
screws at this moment.
3. With the use of a crane (or lifting device),
slowly set the hopper onto the support
plates. Attach the support legs to the
hopper using the supplied hardware.
Drawing # 4
4. Level all components prior to tighten the
cross braces using bolts, nuts and washers
at meeting point # 2. Anchor the hopper
section into the ground using anchor bolts
(not supplied).
5. Withdraw the crane only when all
components are firmly in place.
