1.0 INTRODUCTION
This manual contains all the information necessary in order to use the machine correctly. The user is
requested to read it thoroughly and follow the directions it contains carefully. It is also important to keep the
booklet in a suitable place out of harm’s way. The content of this manual may be changed without notice in
order to include variations and improvements to units which have already been sent out.
2.0 DESCRIPTION OF THE FUNCTIONS
The CLEAN AIR series of centrifugal extractor fans are designed for use on all types of machine tools using
emulsified or neat lubricating oil coolant. The range comprises three models which, fitted with various
impellers and motors, offer a wide selection (up to 6 different combinations) of extraction flow rates,
depending on the size of the machine tool to serve. All the models of extractor fans can be used in
combination with pre- and post-filters at any time, depending on the work carried out and the materials
processed by the machine tool. This ensures the right configuration for the specific problem.
Pic. 1 Pic. 2
Polluted air from the oily particles is conveyed into the mist collector due to the negative pressure effect
exerted by the special backward-inclined impeller which, thanks to the high tangential speed imparted to the
air and the configuration of the extractor fan casing, imparts a powerful centrifugal and coalescent effect
which is able to bring together the larger micro oil particles. These are turned back into liquid to then be
evacuated and recovered through the two drainage tubes. Then, the air is conveyed to the second stage of
filtration consisting of a stainless steel drop separator, fitting CLEAN AIR in a special inclined position able to
grant higher surface of air impact, so higher efficiency. After the drop separator the air is conveyed to a re-
generable coalescing filter with a high storage capacity, which binds and protects a cellulose cartridge with a
large filtering surface area. The air purified in this way, can be released back into the environment.

The dual combination of dynamic reduction and static filtration guarantees a high level of pollutant removal,
which can be further elevated through post-filtration (see picture 2).
3.0 DIRECTIONS FOR USE AND LIMITS OF USE
The CLEAN AIR series of filters has been designed, according to the specificity of their different versions, to
filter neat or emulsified oil mists with modest amounts of dust which are produced in mechanical industry
processing and in particular in turning, milling, boring and grinding.
THE FILTER IS NOT DESIGNED TO TREAT VAPOURS WHICH ARE NATURALLY FLAMMABLE OR EXPLOSIVE
OR BECOME SO DURING A REACTION.
THE FILTER IS NOT SUITABLE FOR FUMES FROM HARDENING TREATMENTS OR IN CASES WHERE THE
FUMES ARE AT A HIGH TEMPERATURE.
IN THE PRESENCE OF FUMES, MICRO OIL MISTS AND VAPOURS THAT COULD BE PRODUCED AS A RESULT
OF HEAVY PROCESSING (HIGH REMOVAL LEVELS, HIGH-SPEED CUTTING, COOLANT COMBUSTION), IT IS
ESSENTIAL TO CARRY OUT POST FILTERING THROUGH A CARTRIDGE.
IT IS COMPULSORY TO EARTH THE FILTER BY CONNECTING THE CONTACT POINTS TO A COPPER PLAIT WITH
A SUITABLE CROSS SECTION (A CROSS SECTION OF 2.5 MM² IS RECOMMENDED), SECURED TO THE
ARTICLE, TAKING CARE TO MAINTAIN CONTINUITY.
A HIGH LEVEL OF SEPARATION OF THE CELLULOSE CARTRIDGE FILTER (RESIDUAL <0.1%) IS ONLY
GUARANTEED WITH FILTRATION RATES UNDER 0.05 M/S, WITH INCOMING CONCENTRATIONS OF
POLLUTANT OF 200 MG/M3 AND WITH INCOMING PARTICLES WITH A GRANULOMETRY OF BETWEEN
0.8 AND 5 µM.
A HIGH LEVEL OF SEPARATION OF THE TEFLON-COATED POLYESTER POST-FILTER, FOR THE VERSIONS
WHERE APPLICABLE, (RESIDUAL <0.1%) IS ONLY GUARANTEED WITH FILTRATION RATES UNDER 0.05
M/S, WITH INCOMING CONCENTRATIONS OF POLLUTANT OF 200 MG/M3 AND WITH INCOMING
PARTICLES WITH A GRANULOMETRY OF BETWEEN 0.2 AND 2 µM.

THE CROSS SECTION OF THE TWO OIL DRAINAGE TUBES MUST BE THE SAME AS THAT OF THE DRAINAGE
CONNECTOR. THIS MUST BE CONNECTED TO A WATERTIGHT COLLECTION TANK, TO THE MACHINE’S OIL
RECOVERY SYSTEM OR THE CENTRALISED DISTRIBUTION SYSTEM. PLEASE NOTE THAT IT IS FORBIDDEN
TO DISPOSE OF THE OILS INTO THE ENVIRONMENT.
The emulsified/neat oil mists (air + liquid pollutant with particle size between 0.8 and 10 microns) are
generated by the (purely mechanical) action of the rotating parts such as tools, pieces being processed etc.
The emulsified/neat oil vapours (air + liquid pollutant with particle size between 0.2 and 0.5 microns) are
generated by thermal action (heat of friction between the piece and tool, heat from the electric resistor
which develops in induction hardening) and by pressure (pre-nebulised cooling systems, forced high-pressure
lubrication).
Any act which compromises the functionality, integrity and/or safety of the machine
structure, the internal equipment, both electrical and mechanical and any control and
connection component is considered improper use. The MICRONFILTER support service is
always available for any further information about using the product.
4.0 PRELIMINARY INSPECTION AND INSTALLATION
CLEAN AIR series filters and their relative accessories/optional reach the customer fully assembled,
protected by suitable packaging.
IN ORDER TO MOVE THE MATERIAL, USE APPROPRIATE LIFTING EQUIPMENT AND TAKE ALL THE SAFETY
PRECAUTIONS ENVISAGED ON THE CONSTRUCTION SITE.
After removing the material from the packaging, make a visual check that it has not been damaged during

4.1 INSTALLATION
The mist collector must be installed by qualified personnel only.
CLEAN AIR series filters are installed near the machine tool and connected via rigid or flexible pipelines, to
be secured to the collection systems using clamps. It is advisable not to exceed a radius of 4-5 m around the
machine. It is also advisable to place them in protected locations to avoid collisions with the handling
systems.
The unit can be mounted BOTH horizontally and vertically and must be secured with the appropriate feet
on the stand, on a shelf or directly on the machine tool.
To dampen any vibrations caused by rotating parts, it is possible to use anti-vibration mounts (supplied); in
this case, it is necessary to secure the CLEAN AIR using two steel cables so that if the anti-vibration mount
should break, the machine will not fall from its position.

The CLEAN AIR filter, upon request, comes with HORIZONTAL installation kit.
We recommend , whenever possible, to remove the panel from the machine
tool identified for the housing unit, in order to carry out all the installation
steps in complete safety. As a first step, using a meter and a pen, locate the 4
points for the INSERTION of anti-vibration mounts.
Once reported 4 points for anti-vibration mounts (for precise measurements
refer to section 8.0 of this manual) drill yhe mavhine tool roof by 8 mm drill
bit. At this point, using the flange of the sleeve that came with the kit, mark
with a pen the inner circumference of the flange of the sleeve and the 4-holes
mounting flange.
Repeat the operation of drilling with the drill and, using a suitable tool (for
example a jig saw) to cut the sheet along the entire circumference. At this
point you can bolt the suction hose. Take care to properly apply silicone
between the plate of the machine tool and the flange, to prevent possible
leakage of oil (if a die-cut gasket is not included).
Repeat the drill with the drill and using a suitable tool (for Screw the 4 anti-
vibration mounts (included in delivery) in the inserts of the vacuum, then
screw the suction hose to the lid of the CLEAN AIR , take care to properly
apply silicone between the cover and flange, to prevent possible leakage of
oil (if a die-cut gasket is not included)
Is now possible to fit the CLEAN AIR mist collector unto the 4 holes previously
made, take care to properly tighten the nuts onto the threads of anti-
vibration mounts to lock properly the mist collector. At this point you can
connect the two sleeves together with the hose supplied with the kit.
Using the drain hose and the T connector merge the two drainage pipes as
shown in the picture, leaving a portion of the tube sufficient to reach the
desired collection point. CLEAN AIR mist collector , after these steps, is ready
to be placed on the machine tool for the next electrical connection, in this
regard refer to Chapter 11.0 of this manual. In the left picture Pictured there’s
an example of CLEAN AIR installed horizontally.

4.3 VERTICAL INSTALLATION
REQUIRED: 1 SLEEVE AND THE RESPECTIVE FLANGE AND A SEAL WITH ITS FLAT FLANGE

CLEAN AIR MIST COLLECTOR, upon request, is provided with VERTICAL
installation kit to properly mount the suction unit on the machine tool. We
recommend that, whenever possible, to remove the panel from the machine
tool identified for the housing unit, in order to carry out all the installation
steps in complete safety. As a first step, using a meter and a marker pen, draw
the 4 points for the inclusion of anti-vibration mounts and suction hose.
Unlike horizontal installation, in this case holes have to be performed on a
single template. Inside of points scored for anti-vibration mounts, you have to
draw the hole for suction, paying attention to the measurements, because the
suction hole IS NOT CENTERED at the intersection of the axes of the lid.
IMPORTANT: To design the suction hole using DIAMETER AS THE
CIRCUMFERENCE OF INNER FLANGE SLEEVE INCREASED BY 20 mm.
Operare con il trapano e il seghetto come descritto nel capitolo precedente
per ultimare la preparazione del pannello. Una volta ultimate le lavorazioni
accertarsi che la guarnizione fornita con il KIT, combini con la foratura.
IMPORTANTE: la guarnizione deve essere bloccata con la SPECIFICA FLANGIA
PIATTA fornita con il KIT.
Working with the drill and the saw as described in the previous chapter to
complete the preparation of the panel. After the completion of work to ensure
that the gasket supplied with the kit, combine with drilling. IMPORTANT: The
gasket must be locked with the FLAT FLANGE SPECIFICATION supplied with
the kit.
ALWAYS USE SILICON BETWEEN INLET SLEEVE AND CLEAN AIR BODY FOR AVOIDING
LEAKAGES
Prepare the drainage as described in the previous chapter, turn the CLEAN AIR
90 ° and invite the sleeve into the hole, taking care not to damage the seal.
The gasket has the inner diameter smaller than the suction sleeve in order to
ensure sealing.
Screw the threads of anti-vibration mounts the bolts to permanently block the
mist collector. In the two photos on the left some detail of final installation.

The filter extraction outlet must be made on the machine fairing at the OPPOSITE SIDE (or even further)
from the tool processing point, in order to avoid any uptake of solid material or excessive intake of coolant
(see pic.1: CORRECT INSTALLATION and pic.2: WRONG INSTALLATION)

5.0 USING AND INSTALLING THE PREFILTER “PF” or “PRECLEAN AIR ”
PF series pre-filters can fit also CLEAN AIR , when needed, ain all cases where there are high levels of
production of oil mists together with dust and metal shavings. For all the limitations of use, the points
mentioned in chapter 3.0 apply.
5.1 INSTALLING THE PREFILTER “PF” or “PRECLEAN AIR ”
PF series pre-filters normally (when ordered with) come already assembled together with the CLEAN AIR mist
collector directly from MICRONFILTER. If this is not the case, proceed as follows:
1. Place the PF on a flat surface.
2. Screw the four M8 anti-vibration mounts (supplied) into the blind inserts on the top of the PF (pic.1)
3. Place the CLEAN AIR on the anti-vibration mounts and tighten the M8 nuts (supplied)
4. Fit a sized hose to connect the CLEAN AIR coupling to that of the PF (fig. 1).
5. Use the two-wire hose clamps (supplied) to secure the hose firmly to the couplings.

7.0 INSTALLING CLEAN AIR AND PRE-FILTER ON THE STAND
In all cases where it is not possible to place the mist collector with its relative pre- and post-filtering accessories directly
onto the fairing of the machine tool, it is possible to install the unit on a support stand. The stand (optional) is normally
provided separately to the CLEAN AIR mist collector. To connect it, proceed as follows:
1. Place the stand in the immediate vicinity of the machine tool, taking care to position it as close as possible to the
extraction outlet on the fairing.
2. Drill holes in the floor, copying the distance between centres on the lower anchor plate (see diagram), using
appropriate anchor bolts (we recommend the use of M8 metal expansion bolts for concrete floors).
3. Assemble the upper rises supplied together with the stand on the upper plate, screw on the anti-vibration mounts
in the seats fitted with inserts.
4. Lift the extractor fan (fitted with pre-filter where applicable) using suitable equipment and place it on the anti-
vibration mounts then tighten the retaining nuts.

9.0 FILTER MAINTENANCE AND REPLACEMENT
Do not perform maintenance while the machine is operating or connected to the electrical energy
source. During these phases, remember to disconnect the plug to prevent unwanted start-ups.
In order to keep the machine in perfect working order, the following operations must be carried out:
§check the condition of the electrical power cables;
§clean the various components comprising the filtration device. To access the filter, loosen the closing screws and
remove the cover (pic. 1)
§Remove the cover and take out the filter cartridge (pic. 1)
§Remove the coalescing filter from the cartridge (pic. 2) and check the wear of both. Replace if necessary.
Coalescing filter: this is the filter whose role is to facilitate the condensation of the oil mists and retain
any coarse impurities. Clean using a detergent solution in a pressure washer at low pressure and about 40 °C (this
operation can be carried out no more than twice). Allow to dry thoroughly before reinstalling. Careful maintenance of
this filter allows the cellulose cartridge to last longer.
Cellulose filter: this is the high efficiency filter that traps the oil mists. Check its condition visually. As it
is a storage filter, its duration is variable and depends on the type of processing and its intensity.
Polyester post-filter (optional): this is the high efficiency filter that traps the micro
impurities, vapours and combustion fumes. As it is a storage filter, its duration is variable and depends on the type of
processing and its intensity.
Dispose of the used filters carefully, sending them to specialised disposal companies in compliance with applicable
legislation.

9.2 PRE- FILTER MAINTENANCE AND REPLACEMENT
Do not perform maintenance while the machine is operating or connected to the electrical energy
source. During these phases, remember to disconnect the plug to prevent unwanted start-ups.
The prefilter has 3 filters with increasing filtration efficiency of which 2 are completely regenerable.
In order to keep the machine in perfect working order, the following operations must be carried out:
§ Remove the cover and take out the filters (see the picture)
§ If necessary, clean the metallic filter (3) and the drop separator (2) using a detergent solution in a pressure washer
at low pressure and about 40 °C. Allow to dry thoroughly before reinstalling. Careful maintenance of these filters
allows the internal CLEAN AIR filters to last longer.
§ The acrylic filter (1) is not re-generable so its duration is variable and depends on the type of processing and its
intensity.
