Description

Absolute (HEPA) filters are used in a wide range of applications such as clean rooms, operating theatres, 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.

The filtration medium 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.

Selection of Filter Construction °C:
Spacers:
Aluminium spacers (up to 250°C and 100% RH for aluminium spacers).
Casings:
For temperatures up to 120°C chipboard. For temperatures above 120°C galvanised or zintec steel casings (up to 250°C )
Sealants:
Standard Urethane Sealant is suitable for temperatures up to 120°C. Temperatures above 80°C and up to 250°C use a 2 part silicone.
Gasket:
Filter gaskets are closed cellular polyethylene with sealed butt joints at corners usually 20mm x 6mm.
Filter Paper:
Filter paper used is water repellent (i.e. suitable For 100% RH but no free moisture).
