NO-DIAPHRAGM FILTER AND/OR SOLID FRAME FOR FILTER

摘要

FIELD: process engineering.SUBSTANCE: invention relates to air filtration. Housing cooling device filter comprises load-bearing structure to be fitted in the housing. It includes the shim tightly hooked with said load-bearing structure that can be engaged with the housing. Filter material rests on load-bearing structure. Said filter material represents a no-diaphragm filter material including high-efficiency tangle of fibres containing hydrophobic fibres increasing composite class to above MERV 14. Filter element is charged electrostatically to form a charged dielectric to make filter material water impermeable and to pass the test in acid mist in compliance with standards GR-487-CORE and ASTM B 117.EFFECT: higher efficiency of filtration.25 cl, 19 dwg, 3 ex, 2 tbl
