PZL Sędziszów offers a line of air filters dedicated to the transport industry.
With the most demanding users in mind, we created 4 versions of the filter which differ in filter paper or packaging. According to the design documentation, identical sealing flange moulds were used for the filters. In addition, the same reinforcement, cover and fastening strip were used.

Filtering material
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.
Protecting paper
An additional external cover, protecting the filter.
Strands of adhesive
Ensure stability and uniform crimp distribution during filter operation .
Gasket
made of highest quality material, resistant to variable atmospheric conditions, ensures tightness between the filtering material and filter body.
FILTER CODES:
Internal protecting insert
Present in some designs.
Its purpose is filtering in case of main insert damage and protecting the engine against impurities during filter removal.
Unique packing system
Protects the filter as much as possible against moisture that causes crimp deformation. Our filters are vacuum-packed, in a bag containing desiccant .
Comparison of filters: Without foil & With foil
