Pneumatic Knockers

SCUA’s pneumatic knockers provide elastic shock to the sides of bins, chutes and hoppers which prevent material from settling. Bridging, siphons and residue formation often occurs near the actual discharge points. Depending on the size and configuration of the bin or chute, a number of knockers could be fitted at trouble spots.

The knockers, available in three sizes (40mm, 50mm, 70mm and 100mm piston), are highly versatile and percussion rates can be varied for different applications by adjusting air flow/pressure.
