MFD Spare Parts FAQs
Straight answers to the questions people ask most when choosing spare parts for a mobile fume and dust filter unit.
What spare parts are in this category?
They are replacements for a mobile, wheeled fume and dust filter unit: filter cartridges, motors, fan wheels, motor protection switches, castors and wheels, housings, covers, spark arrestors, pollution indicators, hose sets, collars and small fixings.
They let you keep the unit performing at its best between services.
How do I identify the right part for my unit?
Read the data plate for the unit type, voltage, phase and frequency, then use the manual or parts list. Many parts depend on the electrical supply, such as the motor, fan wheel and motor protection switch.
Note the exact specification and send a photo if you are unsure, and our team can help you choose.
When should the filter cartridge be replaced?
Replace it when airflow remains low after any cleaning the unit allows, when the pollution indicator shows the filter is loaded, or when it is damaged or wet.
The interval depends on the amount and type of dust and fume and how many hours the unit runs, so it varies a lot between users.
What is the spark arrestor for?
In welding, hot particles can be drawn into the hose and reach the filter. A spark arrestor catches larger sparks before they land on the media, reducing the risk of damage or a smouldering filter.
Keep it clean and replace it if damaged, as a blocked one reduces airflow.
