MFS Spare Parts FAQs
Straight answers to the questions people ask most when choosing spare parts for a mobile self-cleaning filter unit.
What spare parts are in this category?
They are replacements for a mobile filter unit whose cartridges are cleaned automatically by pulses of compressed air. The range includes filter cartridges, valves and diaphragms, the cleaning mechanism, pressure regulation and gauges, a compressor unit, pressure switches, control boards, relays, buzzers, motors, fan wheels, castors and covers.
How does the self-cleaning system work?
A short burst of compressed air is fired back through the cartridge to knock the collected dust off the surface, and the dust falls into the collection area. This keeps airflow up and extends the life of the cartridge.
The cleaning cycle is controlled by a pressure switch or a timer and control board.
The filter is not cleaning itself. What should I check?
Check the compressed air supply or the built-in compressor first, then the pressure regulator setting, the valve and its diaphragm, and the control board and pressure switch. A blocked or leaking air line can also stop cleaning.
Isolate the electrical and air supply before opening any part.
What does the magnetic valve do and why does it fail?
It opens briefly to release the pulse of air to the cartridge. The diaphragm and spring inside wear with use, and dirt or moisture in the air supply can cause it to stick or leak.
Signs are weak or constant air release, or no pulse. A diaphragm and spring replacement set often restores it.
