Fan coil filters produced on a wireframe are mostly used to protect heating and cooling windings, fans, and ducts from coarse dust in various air treatment devices in the HVAC sector. Fan coil filters are made of synthetic non-woven filter material, and these filters can be produced in different sizes according to the dimensions of the opening that needs to be covered. Fan coil filters are lightweight, simple in design, with a low-pressure drop, and have a long and efficient life cycle.
