filter media. The clean air then moves through the tube sheet section and into a
clean air plenum at the top of the module.
There are three main designs of the FabriPulse M: standard hopper design,
bin vent design, and integral fan design.
The standard hopper design will have either a remote mounted or top
mounted fan, with a standard hopper.
The bin vent design will not have a hopper and does not come with a fan.
This is used to vent large areas, like a silo, by differential pressure between the
silo pressure and the atmosphere.
The integral fan design is the same design as the standard hopper design,
but with a fan that is integral to the top of collector.

Purpose and intended use
The FabriPulse M is intended to be used for relatively dry nuisance dusts,
with loadings generally less than 8 grains per cubic foot (8 gr/ft
3
). Typical
applications a FabriPulse M is used for include woodworking, metalworking,
chemical, mining, and food processing. The standard bag media that is used in the
FabriPulse M should be suitable for the intended application.
Contact AAF International for assistance on a bag design for your
application. It is recommended that you use only AAF International bags on AAF
International equipment.

Normal Operation
During normal operation, air enters the FabriPulse M dust collector through
the high inlet and moves downward through the dirty air plenum, in true “down
flow” fashion. The cleaned air passes through the filter elements, while dust is
collected on the outside surfaces of the elements. Clean air flows through the
center of the elements into the clean air plenum, where it exits through the clean
air outlet.
During filter element cleaning, a pulse controller automatically selects the
element or pair of elements to be cleaned, activating solenoid valves which open
air diaphragm valves. High pressure air pulses directly into the center of the
selected element, or pair of elements, for 100 milliseconds, blowing collected dust
