PNEUMATIC  KNOCKERS

Pneumatic knockers enable sticked material to detach from silo, container and pipe walls. Compressed air is injected under the piston and puts a spring under tension. After release of air, the piston moved by spring strokes the basis. The basis is equipped with an elastomer washer to protect stricken surface.

FKL in – type pneumatic knockers

Force and frequency of stroke variable.

Properties:

  • two modes of action: single or interval impact mode,
  • controlled power of stroke and controlled constant work,
  • lubrication-free,
  • working temperature from -40°C to 150°C,
  • flexible range of applications.

Construction:

  • four bolts attaching to the basis,
  • anodized, hardened aluminum casing,
  • steel piston,
  • elastomer washer.

Usual applications:

Releasing sticked materials from silo and container walls, compacting and loosening bulk material.
