Specification text

Pocket filters PFG made of non-woven glass fibres as prefilters or final filters for the separation of fine dust in ventilation systems. Filter pockets provide a high dust holding capacity at alow initial differential pressure. Pocket filters made of non-wovenglass fibres are available in standard and special sizes; variable number of pockets and pocket depth; filter groups ISO ePM10 and ISO ePM1 according to ISO 16890. Pocket filters made of non-woven glass fibres are Eurovent-certified and compliant with VDI 6022 in terms of hygiene. The pocket filters with optional EX protection PFG-EX may be used in areas with potentially explosive atmospheres of zones 1 and 2 as well as zones 21and 22 (EX II 2G Ex h IIC Gb and EX II 2D Ex h IIIB Db). The filters must be connected to the ground potential. All conductiveand dissipative parts must be connected together and grounded. Conductive dusts are excluded from the application. Under nocircumstances should metallic foreign materials enter the filter. Ambient temperature range: -40 °C ≥ Ta ≥ +80 °C
