Description

HEPA High-Efficiency Particulate Air filters are widely used to separate airborne particles or particulate air impurities down to 0.3 µm (i.e. viruses, germs, toxic dust).

HEPA filters are installed where the maximum of air cleanliness is demanded. This particulate filter is needed on the air intake side for the separation of suspended matters e.g. viruses, germs, toxic types of dust, aerosols etc.

These filters are also installed on the exhaust air side if pathogens, toxic or radioactive particles must be removed from the exhaust air.

Construction

• • Filtering Media
    Micro glass fiber filter paper, pleated with Aluminium spacers used for separating consecutive pleats.
  • Frame
    Al. Anodised trays manufactured using CNC machine screwed together to form a rigid frame.
  • Adhesive 
    An epoxy-based adhesive used for the leak-proof joint between filter paper & frame.
  • Gaskets
    Sponge rubber gaskets provided for sealing of filter units mounting frame.

Performance

Recommended for operating efficiency of 99.97% down to particle size of 0.3 microns by DOP (Di-Octyl-Phthalate) test as IEST standard Pressure Drop – 25mm WG for 100% rated flow

Operating Conditions

Ambient temperature (max. 50 degree C) and Humidity up to 100% RH

Testing

Each single HEPA filter is individual performance tested according to the IEST standard.
The test-status is documented by the individual serial number.

Application

Clean room filtration, process air, operation rooms, Laboratories, clean work benches & for supply and exhaust air .
