FORCE™ dust collectors feature Roto-Pulse® cartridge-cleaning system. This automatic, incrementally rotating filter cleaning system uniformly cleans 100% of cartridges' surfaces using pulsed air. Time between pulses and duration of each pulse are factory pre-set for optimal cleaning but can be adjusted for various applications or processes. Promoting life of filters and compressor, Roto-Pulse is engineered for reduced-noise operation and compressed air consumption.
