applications
The capture system and the
electrostatic filter apparatus are
connected by an automatic fire
damper, which can prevent fire from
spreading.

03
The M91® guarantees periodic cleaning
of its filters with a programmable
washing cycle that uses water
and detergents through a ramp of
oscillating nozzles. The washing cycle
can be programmed to take place at a
convenient time. Plant activation and
deactivation can also be completely
automated.
SELF-CLEANING
02
The M91® purifier is a filtration device
to ensure healthy air in production
contexts where the vaporization of
lubricating fluids used for machine
tools creates a thick mist composed
of droplets with an extremely small
diameter able to reach the deepest
areas of the respiratory system .

01
During normal operation, oil can be recovered in a specific container and
possibly reintroduced into the production cycle after the solid residue has
been filtered out.
The number of cells, which are arranged on several levels, can vary depending
on the total capacity of the plant established during the planning stage: this
is a modular plant, which can be easily built in different sizes. The inside of the
purifier is widely accessible through several inspection hatches and doors, all
of which have accident-prevention safety switches.
It is necessary to start with correct air capture.
Once the aerosol is captured, it is sent to a precipitator for abatement: an electrostatic filter system channeled to collect the
effluent from different machines into a single main reservoir.
This specific type of filter is selected for its high efficiency oily mist abatement, reduced load losses, and the self-cleaning
effect that results from the oily layer dripping from the collection plates.
To limit deposits in channels as much as possible, it is necessary to keep transfer speeds relatively high, and also to construct
the main reservoir with a slope so that the condensates will flow towards one end.
THE M91®
PURIFIER HAS SEVERAL ALUMINIUM
FILTER CELLS ARRANGED PARALLEL INSIDE A METAL
PLENUM WITH A HOPPER BOTTOM. IT IS EQUIPPED
WITH A SHUTTER GATE FOR RECOVERING DROPLETS
