Plymovent Stationary Filter Units FAQs

Straight answers to the questions people ask most when choosing and running stationary welding fume filter units.

What is a stationary filter unit and where is it used?

A stationary filter unit is a fixed fan and filter assembly that draws contaminated air from one or more extraction points, cleans it and either returns it to the workshop or discharges it. Sizes range from small units serving a single arm to central systems serving a whole workshop.

They suit permanent welding stations, production lines, cutting tables and general fume and dust control.

What are the main filter types, and how do they differ?

Most welding fume units use a filter material, often pleated cartridges, to trap particles. Some are replaced when full, while others clean themselves in place with pulses of compressed air that knock dust into a collector. Other designs charge particles and collect them on plates that must be washed or wiped clean.

The right choice depends on the fume, how many hours the unit runs each day and the maintenance you can carry out. Check the data plate and manual of the unit you are considering for the filter type, the cleaning method and the service interval.

Single-arm units, multi-arm units or a central system - which should I choose?

A single unit with its own arm is simple and good for one station. Several arms on one unit work if the stations share a space and are not all used at once. A central system with ducting suits many stations and gives one place to maintain the filter.

Central systems need more design work and ducting, and their balance matters, but they can be easier to look after in a large workshop.

Can the cleaned air be returned to the workshop?

Often yes, if the filter is rated for the fume and the process does not give off hazardous gases or vapours the filter cannot remove. Returning air saves heating energy and avoids drawing cold air in through the building.

Check the manufacturer's guidance and your risk assessment. Stainless steel, coated materials and some consumables need extra care, and some applications require discharge to the outside instead.
