In air filters, used are materials characterised by a closely defined air throughput and impregnation type and effectiveness. Carefully selected mixtures of cellulose fibres are impregnated with phenolic and epoxy resins. In order to increase their effectiveness, an addition of synthetic fibres is often used. Currently, in filters made by PZL FILTERS, self-extinguishing and FR (flame retardant) filtering paper is used as standard.
