Air filter design
- Filter frame is made of impregnated, moisture-resistant cardboard.
- Filtering material is a multi-layer synthetic filtration material which meets requirements of ISO 16890 and EN 779:2012 standards.
- The pleats of filtering material are crimped by gluing them together, thus ensuring the least possible resistance to air flow and a large dust trapping area of the filtering material.
- Filtering material is glued to the frame on all four sides, thus ensuring that dust does not enter the room through filter leaks.
