Cardboard harmonica-type filters made of two layers of strong cardboard. The design of the filter strongly reduces the speed of the exhaust air and the paint dust sticks to the filter. This type of filter is easy to install and replace.
Suitable for use in painting booths and hand painting walls, automatic painting machines to contain paint dust, using many paints and varnishes. It works best when the paint dust is very sticky.
NOT SUITABLE for quick-drying paints with dry, non-sticky dust.
