The air purged filters of the AF model line are used in bins or conveyor scales of vacuum- and pressure-conveying systems, serving to separate the product from the conveying air. Filter cleaning of the hose filters is effected automatically via compressed-air pulses.
How it works
The dedusting of the diaphragm valve can be effected centrally via PLC or via a closed control. The interval periods and the cleaning-pulse lengths are preset in the filter control. Optionally, a dedusting via differential pressure, can be effected. A diaphragm valve opens and closes the port from compressed-air chamber to compressed-air distributor. Via a pipeline system, the compressed air is directed directly through the individual hose filters. The special design of the nozzle bars ensures highly uniform and intensive cleaning of the individual hose filters. The standard features include earthing of the filter plate, connecting pieces for measuring the differential pressure, and a lifting/sliding device for inspection and maintenance purposes. The latter makes it possible to move the upper part of the filter laterally on profile tracks, making the individual hose filters freely accessible for quick inspection as well as for cleaning and maintenance work. Condensate forming in the compressed-air chamber can be let off through a condensate draining device. The built-in pressure-reducing valve serves to set the air pressure required for filter cleaning.
