Gentle and Cost-Effective Cleaning of Filters

Scavenging carriages with matching fans used to be the main method of gently cleaning dust filters. Although effective, such systems involve a large number of moving parts. Buschjost has developed the 82900 and 82960 series of single-stage filter pulse valves as an innovative alternative. They combine the advantages of scavenging and pulse cleaning.

The new valves have an extended flow characteristic that cleans the filters with a steadily increasing volume of air. They work in a similar way and achieve results comparable with scavenging carriages. Their much flatter flow characteristic than filter pulse valves provides gentle cleaning of high-quality filter bags.

There is a choice of internal or external (advisable for extreme conditions) pilot actuation. Versions are available for dusty gas temperatures of up to 140 degrees. The strong aluminium body is designed to take DN40 air connection pipes. Its clever shape allows installation of very compact banks of valves at a spacing of 120 mm. The actuating solenoids can be simply twisted on and off the body of the valve for reliable replacement. For a long, maintenance-free service life, all of the valves are fitted with quality TPE diaphragms that have been subjected to long-term testing.
