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 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.
Why is clean, dry compressed air important?
Water, oil and dirt in compressed air can damage valves and diaphragms and can wet the filter media, which then clogs. Air preparation such as filters, dryers and drain points is normally used to protect pulse-cleaning systems.
The air quality and pressure your unit needs are set by its maker, so check the manual and data plate for your own machine. If you feed the unit from a site air supply, make sure it meets those requirements and drain any moisture traps regularly.
