clean air outlet.
1.1.2 Filter Cleaning
RVS collectors are intermittent duty.
Cleaning
is done only after the fan is shut off and an
appropriate fan run-down time is completed.
Filter cartridge cleaning is accomplished by high
frequency vibration.

The Torit
RVS dust collectors provide high
efficiency, intermittent duty air cleaning by means
of an exclusive Torit filter cartridge. The filter
element is cleaned automatically each time the unit
is shut off unless an optional delta switch system is
included. With the optional delta pressure switch,
the filter is cleaned only after the airflow across
the filter reaches 3" pressure drop.

1.1.1 Normal Operation
Dust enters through the cabinet inlet and is
deflected downward by the inlet deflector. It then
passes through a tight mesh screen on the outside
of the filter. The screen, spaced 1-inch away from
the filter media, catches fibrous dust, while fine
particles pass through the screen and collect on the
outside surfaces of the pleated filter cartridge.
Clean air flows up through the center of the filter
cartridge into the blower, through the silencer

the filter restriction is greater than
the pressure switch set point of 3"
