Roto-Pulse

The automatic, incrementally rotating Roto-Pulse uniformly cleans 30–40% more filter surface than conventional reverse-pulse systems. The additional area of clean media means a lower air-to-cloth ratio requirement, lower grain loading, more-efficient filter cleaning, and longer filter life. The system operates by pulsing air into a specially designed stainless steel perforated tube. As the air enters, the tube rotates a specified number of degrees, distributing the pulse of air across the length of the cartridge’s inside surface and dislodging clogged dirt from the outside of the cartridge. The number of increments per revolution can be adjusted, as can the time between pulses, for maximum flexibility. It runs up to 15 dBA quieter and uses less compressed air than reverse-pulse systems.
