Pulse Jet Filters DatasheetSource: Schenck AccuRate
All Mac Process Pulse Jet models use compressed air to clean the internal filter media. Particle-laden air enters the housing and passes from the outside to the inside of the filter media. The dust collects on the exterior of the filters while the cleaned air flows upward and exits through the opening at the top of the filter into the clean-air plenum.
The cleaning cycle starts when the adjustable timer activates a high capacity diaphragm valve. This valve opens the header pipes above the filters for 20 to 60 milliseconds. Compressed air nozzles, located in the header pipe, direct the air pulse into the individual filters. As the compressed air bubble travels down the length of the filters, the collected dust is accelerated away from the filter surface.
