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.
How do I identify the right part?
Use the data plate for the unit type, voltage, phase and frequency, then the manual or parts list. Many parts differ between versions, such as the control board, compressor and motor.
Note the markings on the old part and send a photo if unsure. Our team can help you choose.
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.
