Pocket filter
The medium and fine stage of ventilation: deep pockets give a large filtration area, so the filter lasts longer and holds more dust.

Frame and deep pockets
Pockets sewn from synthetic media are fixed in a galvanised frame. Stitched spacers inside each pocket stop the pockets from ballooning in the airflow and touching each other.
- Pocket depth: 360, 500, 600 mm
- Synthetic or glass fibre media
- Frame: galvanised steel or plastic
Frame, pockets and spacers
Internal stitching keeps each pocket in shape: without it the pockets collapse onto each other and the working area shrinks.
Air passes through the pocket walls
Air enters the pockets and leaves through their walls: fine particles are captured within the depth of the media. Deep pockets mean low velocity and low pressure drop.
- Service life: 6–12 months (by ΔP)
- Energy efficiency per ISO 16890
What we need for a replacement
Send the frame size and number of pockets; the class can be given to ISO 16890 or the old EN 779 grade.
