Types: CPL, FP and CVL
The vibrations are generated by a piston deadened by air cushion. These vibrators are silencer

1- with BALL (standard K)
2- with TURBINE (standard WP)
3- with ROLLER (types R and DAR)
The vibrations are generated by the action of the ball, the turbine or the roller turning in their cage under the action of the pressure of the compressed air

Types CFP and FKL
The "CFP" generate successive shocks by the action of a piston of Ø 30,45 or 75mm
The "FKL" generate a powerful shock each time. They must be coupled to a 3-way solenoid valve controlled by automat or a cam timer.
