Filters in paint booths and lines trap overspray, keep the air clean and protect ventilation, drying and heat recovery equipment from excessive contamination. Properly selected filters extend equipment life, reduce maintenance costs, improve the quality of the working environment and ensure a more uniform finish.
Elister offers colour chamber filters for both powder coating, water dyeing as well as automatic colour lines from small hand-held rooms to fully automated industrial solutions.
| Filter | Type | The main task | Where to use |
|---|---|---|---|
| Cardboard folding filter | Self-filter | Catching large paint particles | Paint chamber inlet/first stage |
| Columbus 6-layer paper filter | Pre- / main filter | High capacity overspray filter | Water colour chambers |
| Columbus 7-ply with extra fabric | Pre- / main filter | Even higher catching capacity and lifetime | High throughput lines |
| W250 filter mat | Fine / after filter | Synthetic, 100% plastic fibre filter | Paint booth extraction downstream stage |
| W300 filter mat | Fine / after filter | Multi-layered progressive structure | Lines with increased filtering requirements |
Choosing the right filter depends on four main factors:
Our specialists will help you determine the right filter combination and ensure regular delivery throughout Estonia. We also offer components for colour spaces and lines and full solutions from from manual to fully automatic line.
The paint chamber filter traps paint overspray to prevent it from entering the ventilation system or the outside environment. This protects equipment, improves air quality and ensures compliant emissions.
The changeover frequency depends on the type of paint, the throughput and the design of the chamber - usually measured by the pressure drop across the filter. If the pressure drop exceeds the manufacturer's recommendation (often 250-450 Pa), the filter must be replaced.
A pre-filter (e.g. a cardboard folder or Columbus paper) will catch the larger colour particles. A downstream or fine filter (W250, W300) removes finer particles and protects downstream equipment such as a heat exchanger or fan.

Yes - there are solutions for both technologies in the range. Powder dyeing tends to use regenerable filters and cyclone systems, while liquid dyeing uses paper filters and synthetic filter mats.
The filter ensures strong absorption, long operating time and better filtration. The best overspray filter available.

The W250 filter is a synthetic filter media made of 100% plastic fibre and thermally bonded. The filter media is built up in a stepwise manner. The W250 filter can be used as an after-filter in paint booths behind a cardboard folding or Columbus filter.
The W300 filter is a synthetic filter material made up of different layers of plastic mix. The air side of the filter has a high fibre density. The W300 filter can be used for production processes requiring fine filtration, such as spray booths, drying equipment and as a pre-filter.
The cardboard pleat filter is made of two layers of strong, hard cardboard. The filter works by changing the direction of the exhaust air. By changing the direction of the air, the particles of dye are forced to the bottom of the filter pleat and the air is directed through the lateral air channels of the filter.
