The Mini PulseClean Vent Filter is a new line of miniature bin vent filters. Each unit has one small filter bag or cartridge filter element which is automatically pulse-cleaned with a burst of compressed air. These filters are made to fit the Loss-in-Weight feeder hoppers and Aerolock™ surge hoppers. Similarly, this product fits the need for a small, reliable automatic vent filter and can remain in use for long periods of time without the blinding or maintenance of a static vent sock. A pulse timer or central controller can be used to send the pulse signal.
