Panel filter

A panel filter from konfAir, also called filter cells or cassette filters, can be used in all standard ventilation systems, both for residential, commercial and industrial ventilation to improve air quality. Panel filters in higher filter classes are often used as pollen filters.


High quality panel filter for ventilation

A panel filter from konfAir is characterized by a high utilization of the filter area, a long lifetime and high quality. The filter area is optimized using precision pleats, so each fold is used all the way to the tip, allowing the maximum amount of air to pass. The panel filter is made of a stable, synthetic fiber frame, which together with the structure of the filter, in moisture-resistant synthetic filter media, makes the filter very light. The low weight and exact dimensions make the filter easy to install. When replaced, the entire filter is easily disposed of, along with regular combustible waste.

We produce panel filters with two different types of pleats, Z-line and relim. Panel filters with Z-line are used primarily on the exhaust side or as a pre-filter for panel filters with relim pleating. Panel filters with relim, also called minipleat, are often used on the supply side due to its closer pleats, for example as a pollen filter. We produce filters for various systems such as Vex/Exhausto, Nilan and Airmaster.
