PULSE JET FILTER UNITS

The Pulse Jet Filter is an effective and widely proven system. Its high dust collection efficiency at low cost is the basis for its wide application.

CONSTRUCTION:
The Pulse Jet Bag Filter consists of a bag house comprising of filter bags with the supporting cages, venturies, hopper for the collection of the dust, header, air distribution pipes, pulse valves and centrifugal fan.
The filter module is designed around the seal frame. This is a formed plate containing a series of parallel slots into which a set number of filter cartridges are inserted.
WORKING PRINCIPLE:
The dust laden air enters the PulseJet Fitter at the dirty air plenum where it expands and the air velocity drops. This results in optimum air and dust distribution. Heavy particles are collected in the hopper of the dirty air plenum.
The dust laden air then passes through the filter media, depositing the fine dust on the outside of the bags. Each bag is regularly cleaned by a reverse jet of compressed air. A timer activates the valves at pre determined intervals on a continuous cycle. A short burst of compressed air is released and injected by the jet tube into the filter pad. This causes a brief controlled inflation of the pad to dislodge the accumulated dust cake into the collection facility.
