The pneumatic linear vibrators Series NTP are especially suitable for knocking off material adhering to container walls in funnels, containers, silos and hoppers. Special features of NTP vibrators are: impacts like a rubber hammer or vibration with high peak acceleration.
The linear vibration is produced by a freely vibrating differential pressure piston. In a standard application, the piston knocks against an elastomer impact plate and works like a rubber hammer.
When used without an impact plate, the piston works against an air cushion and reduces noise. Hard knocking versions are available. The frequency can be adjusted by varying the pressure of the air supply and the amplitude by throttling the exhaust.
Lubrication-free operation is possible. ATEX-compliant linear vibrators of the NTP series and units with stainless steel housing are available.
