The WP (formally BD) Pneumatic Concrete Vibrator series utilizes a built-in pneumatically driven motor which has only two moving parts, the vane and rotor. Compressed air is supplied to the vibrator through the air valve and inner hose. Air flows into the rotor, passes through the passage ways in the vane, back through the "air gap" on the rotor and outer holes in the rear flange. This activates the rotor and the vibrator begins to vibrate.

Pneumatic Concrete Vibrator:

• Provides quiet, smooth operation
• Available in four sizes from 1-1/2" through 3"
