Intermittent Duty Cycle Architecture
Unlike pulse-jet systems which clean while running, mechanical shaking dust collectors are intermittent-duty devices. The system must be physically shut down to allow the internal airstream to settle before the cleaning cycle begins. A motorized eccentric shaft aggressively vibrates the filter bags, physically dislodging the accumulated dust cake into the collection hopper.
Woven Filter Media and Air-to-Cloth Ratios
Because the cleaning action relies on physical vibration rather than a shockwave, shaker baghouses typically utilize heavier, woven filter fabrics rather than non-woven felts. Consequently, they require much lower Air-to-Cloth ratios (typically 2:1 or 3:1), resulting in a larger physical footprint for a given CFM compared to modern pulse-jet architectures.
