The single impact pneumatic vibrator or "air knocker" delivers one impact at a maximum frequency of once every three seconds through a five-port spool valve. A timer is used to vary the impact cycle required. Single impactors or "air knockers" act most like a hammer and are most effective for sticky materials because they are less likely than continuous vibration to cause packing in bins and hoppers.

DURABLE - one-piece, ductile iron housing and spring-less design ensure long effective life

SAFE - use of ported exhaust reduces noise levels while pneumatic power allows for operation in hazardous areas

VERSATILE - dual diameter piston allow for mounting at any angle on your bins, chutes and hoppers handling

EASY - all industrial vibrators come with mounting fasteners and a gasket for quick set-up

Make It a Kit - includes a mounting channel, 5 ft. inlet and exhaust hoses w/ fittings, 5-port spool valve and timer
