  Filter box FBK line

Filter box application

Filters are mounted in circular ventilation systems for intake/exhaust air purification. They are used to protect heat exchangers, air ducts, fans and other ventilation equipment from dust.

They minimize wall and ceiling contamination near air diffusers. Coarse filters can be used as the first stage of cleaning before filters that are more efficient.

Filter box installation

The filter design allows fixing on round air ducts using clamps in any position. When assembling, it is necessary to take into account the direction of air movement (it should correspond to the pointer on the filter). During installation, it is necessary to leave space for service access to the filter (cleaning or replacement of the filtering element).

The filter box with a flat filtering element (class -G4) is made of galvanized or stainless steel. The filter box is equipped with connecting flanges with a rubber seal for tight connection with air ducts.

The filtering element is of pocket type (to increase the filtration area) and made of non-woven synthetic material.

It is mounted in front of the fan downstream with the airflow. It is installed with the flange connection. The direction of air movement must correspond to the mark on the filter.
