Working Principle

The DP® Pulse Jet Dust Collector operates on the principle of pulse-jet filtration under negative pressure. Dust-laden air enters through the air + dust inlet (1) and flows into the DC housing (3). A blower installed at the clean air outlet (10) creates negative pressure inside the system, drawing air upward through the filter cartridges (4). Due to this suction effect, dust particles are retained on the outer surface of the filters while clean air passes through and exits via the clean air outlet (10).

As dust accumulates on the filter surface, the pressure differential is monitored by the magnehelic gauge. Based on preset intervals controlled by the timer box, the solenoid valve (6) releases a short pulse of compressed air from the header tank (5). This pulse-jet action dislodges the accumulated dust from the filter surface.

The released dust particles fall downward into the hopper section and are discharged through the rotary air lock valve (8) at the dust outlet (9), ensuring continuous and airtight removal. The cleaned air continues to flow through the filters and is safely discharged, maintaining efficient, dust-free operation.
