Deep Bed Air Filters

F5 Rated, 4 Pocket Bag Filters

Camfil Airepure FourPak Deep Bed Filters are available in standard sizes with an efficiency of F5 and are suitable for general purpose filtration applications in industrial and commercial applications. The FourPak Deep Bed Filters are suited to non-critical applications or as a pre-filter to extend the life of the secondary filter.


FourPak filter media’s are manufactured from bonded synthetic fibres. All media types are moisture and fungus resistant and will not shed fibres into the clean air stream; other efficiencies are available upon request.

Standard mounting frames consist of an outer frame and inner basket assembly as illustrated to the right. The outer frame consists of a 2mm epoxy coated galvanised frame, with a 6mm Epoxy inner basket assembly. Options include 304 and 316 grade stainless steel and reverse flow configurations.


Camfil Airepure can provide an all inclusive air filter maintenance, replacement media service upon request. FourPaks are easily changed out by simply holding the handles at the sides of the inner basket and applying a slight pulling action to disengage the clips at the sides of the outer frame.

The media may then be removed together with the inner basket, or, if preferred, after the basket has been removed. The replacement media is then fitted over the inner basket and reinserted making sure the sides of the inner basket clip over the clip mechanism.
