HEPA Filter / Absolute Filter Applications

Absolute filters (HEPA Filter) are used in a wide range of applications such as clean rooms, operating theaters, research facilities, the electronic and micro-electronic industries, nuclear and pharmaceutical industries and high speed turbines.

Clean Rooms tend to employ the narrow 146mm deep filter and utilise a lower face velocity in accordance with the relevant clean room standard requirements, thus providing a laminar air flow either across the work area or across the complete room depending upon the application.

HEPA Filter / Absolute Filter Construction

The filtration medium in the Absolute / HEPA filter is provided by microfine glass fibres formed into a paper-like surface, supplied in various grades depending upon filtration efficiency required. The filter paper is formed into a close pleated package to provide a large surface area. Spacers of aluminium or hot melt are inserted between each pleat to provide support for the pleat and maximise the surface of the filtration medium.
