>> HEPA Filters ::::

HEPA Filteration technology was developed by the U.S. Atomic Energy Commission to remove airborne radioactive particles. HEPA (High Efficiency Particulate Air) filters are the highest efficiency filters available for filteration of small particulate. Defined by the institute of Environmental Science, a true HEPA filter must capture a minimum of 99.97% of contaminants at  0.3 microns in size. The reason, 0.3 microns is used because it is that size at which all mechanical filters are LEAST efficient in capturing. Other methods of testing do not give a true picture of efficiencies relative to respirable-size-particle (RSP) capture.

  • To be considered a true HEPA filter, it must be capable of removing 99.97% of particles as small as 0.3 microns
  • Recently many people have been enjoying HEPA systems in their homes & offices to remove allergens from the air they breathe.
  • HEPA Filter - Efficiency more than 99.97% at 0.3 Microns DOP.

A True HEPA is also known as an ABSOLUTE Filter because of its efficiency!!

HEPA Filter was developed during World War II & was designed to remove & capture radioactive dust particles from the air which might escape & present a health hazard. Thus it was specifically designed to protect the Human Respiratory System.

HEPA Filters have been traditionally used in hospital operating and  isolation rooms, pharmaceutical and computer chip manufacturing companies. Today HEPA filters are used in a wide variety of critical filteration applications in the nuclear electronics, aerospace, pharmaceutical and  medical fields and in equipment for asbestos abatement, source removal dust cleaning, tuberculosis wards, surgical facilities and other areas where clean and particle free air is essential.

However a True HEPA's efficiency DOES NOT decrease during its life, it actually increases!!

Care must be taken when choosing a HEPA air filter because the most important part is the Power Performance and CFM (cubic feet per minute ) of the blower or Fan motor. A strong fan motor is required and essential because the efficiency of any air filter is meaningless if the unit cannot draw air into the  filter.

Standard sizes HEPA Filters made by us are as under :-

  • 24 x 24 x 12                         1000 CFM

  • 24 x 24 x 6                           500 CFM

  • 36 x 24 x 6                           750 CFM

  • 48 x 24 x 6                           1000 CFM

  • 12 x 12 x 6                           125 CFM

However any tailor made design and sizes can also be manufactured to suit ones requirement.

Different Material of Casings offered are :-

1]         CRCA 16 Gauge Thick Epoxy Powder Coated or Chrome Plated

2]         Aluminum 1.6 mm 2.0 mm Thick, Powder Coated or Anodized

3]         Fire Retardant / Resistant 19 mm Thick Plywood As per IS : 5590/1980

4]         Stainless Steel 304, 1.2 mm 1.6 mm Thick buffed.

All HEPA filters are tested as MIL STD -  282 which is one of the widely accepted industry standard for testing 0.3 micron efficiency and is required for compliance with most nuclear, military and U.L specifications.
