FIELD: ventilation.
SUBSTANCE: invention relates to ventilation, mainly ventilation of living quarters. Frameless channel filter comprises smaller base with guide ring, larger filter base in form of ring with bead and inner auxiliary element, wherein on outer surface of shoulder of larger base is fixed sealing ring, corrugated filter material with opening angle of 10–15 degrees, wherein the corrugated filter material is hermetically connected to the bases and is gradually expanding from the smaller base to the larger base.
EFFECT: technical result consists in improvement of efficiency, as well as in ease of installation of frameless channel filter in air channel, due to the optimum location of the surfaces of the corrugated filter material in the closed space of the air channel and the presence of elements (internal auxiliary element, sealing ring), which increase convenience of filter installation, which increases area of the filtering surface, reduces energy consumption for the filtration process, to ensure passage of air flow through surfaces of corrugated filter material, to provide fast and accurate installation of frameless channel filter into air channel.
