2. COMPONENT DESCRIPTION
a) Control panel with
magnetothermal motor protector switch
Additional optional devices can be installed inside the control panel, such as:

hour counter

indicator lights

disconnector (as alternative to motor protector)

contactor for remote control
contact our customer technical sales department for further information.
b)
Control pressure gauge indicates filter is clogged
The pressure gauge on the unit continuously indicates the clogging level of the final filter; this way, the
condition of the final filter is always under control and replacement can be done promptly. As an optional
feature, a pressure gauge can be installed to monitor the prefilter stage.
c)
Extraction duct : the point where the polluted air enters.
d)
Drain duct : the point where re-condensed liquids are discharged.
e)
The latches with safety springs prevent the machine from opening accidentally. To open, push the
spring upward and release the latch using the opening lever.
Personal safety
– unit integrity
Before releasing the latches, make sure the unit is firmly secured to the
supporting floor with special anti-vibration mounts.
f)
Lifting rings : for lifting equipment.
g)
Anti-vibration mounts further reduce the vibration level transmitted to the structure; due to the
fastening system, they are not subject to dangerous breaking with normal anti-vibration mounts.
h)
Pre-filter stage , made up by three or two progressive filter sectors according to the model, ensures
excellent solid pollution accumulation and liquid drainage capacity. The first prefilter media in expanded
micromesh is totally recyclable (only on emulsion version).
i)
intermediate centrifugal stage , uses a special impeller that continuously removes oil particles or re-
condensed emulsion. The impeller's design prevents vibrations due to clogging and subsequent
unbalancing of the usual centrifugal filters with rotating filters.
j)
final high filtering surface stage, made up of seven glass microfibre and polyester filtering sectors.
The final stage provides an average overall efficiency level higher than 99 % (measured according to
standard AFNOR NFX 44-060).
To solve specific problems (fumes) an additional filter module can be installed:

Absolute with HEPA filtering levels up to H 13 - 99.95 MPPS according to EN 1822
