Applications of the pneumatic knocker for silos FKL-200 In
This pneumatic knocker for silos is particularly suited for:
- Knocking off adhering material on silos, hoppers and chutes
- Cleaning filters, reactors and pipelines
- Wet, explosive or ATEX-classified environments
- Applications requiring adjustable impact force and interval
Construction and operation of the FKL-200 In
The piston is forced against a spring by compressed air ; with rapid bleeding, it then bounces against a baffle plate. In interval mode, impact depends on the time set by a throttle valve, with force adjusted via the three control bores. In single-impact mode, impact is triggered immediately after the 3/2-way valve switches ; several knockers can thus be operated in parallel. The hard-anodised aluminium housing, hard-anodised aluminium base plate and hard Ematal-covered cap protect a steel piston. Lubrication-free, it withstands extreme environmental conditions, wet and explosive environments, and is available with ATEX certification.
