SI – Single Impact Air Knocker

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 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
