Our HEPA or the high-efficiency particulate absorbing filter has a filtration efficiency of 99.97%, for particles up to 0.3 micrometers (µm) in diameter.
The filter medium is fabricated from 100% fire proof micro fiberglass pleated with aluminum/cadmium plated mild steel with an exclusive plastic base adhesive.
Continuous neoprene sponge rubber seals are provided on the filter frame for effective sealing.
The filter has excellent resistance to chemicals including corrosive vapors and most acids except phosphoric acid and hydro solvents which have little or no effect.
It also has excellent electric qualities; it neither absorbs moisture nor undergoes any chemical changes through contact with moisture.
It can operate in temperatures up to 150°C intermittent and 121°C continuous and 100% relative humidity.
These filters are tested by the DOP test method, which is by far the most accurate and stringent test.
These filters have been specifically designed to meet the requirements of clean air in general ventilating and air-conditioning systems in Hospitals, Computer installations, and also in Nuclear, Pharmaceutical, Petro-Chemical, Fertilizers, Synthetic fiber industries and Compressor applications.
The heart of the filter is a reinforced washable synthetic non-woven filter media/fiber glass.
The fiber media is pleated in an accordion format along with a backing of wire/HDPE netting.
The mediums are carefully selected to offer the best possible performance to suit specific needs.
In order to obtain uniformity of dust loading, the filter plates are kept apart by means of aluminum separators.
The complete filter pack is sealed into a rigid cassette of mild steel or aluminum.
The filter is offered in a three piece construction namely the element cassette, the outer casing and the front grill.
For replacement, only the cassette element needs to be changed.
The Micronics fine filter has a filtration efficiency of up to 90.0%, with particle retention >5.0 micron and it can operate at a temperature of up to 120°C and 100% relative humidity.
Before use, the filters are tested in accordance with the specification of BS 2831 Standards.
