Wyco BD Series Pneumatic Concrete Vibrat

Pneumatic Concrete Vibrator - Service Manual (PDF)

The 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 flow 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.

  • Available in four sizes from 1-1/2" through 3"
  • Hose length can be customized for most any application
  • Quick disconnect integrated into hose connectors
