HEPA FILTERS

High Efficiency Particulate Air Filters are made of fine-diameter fiberglass compressed into a fabric-paper sheet, which is then finely pleated to increase the particle-trapping surface area.

A HEPA filter removes a minimum of 99.97% of contaminants at 0.3 microns in size. A micron is One in one-thousandth of a millimeter. High-Efficiency Particulate Air Filters (HEPA Filters), are a form of extended surface media air filters previously known as High Efficiency Particulate Arrestors. A ´True´ HEPA filter must be at least 99.97% efficient - allowing no more than 3 particles in 10,000 to penetrate the filtration media.

To Illustrate - A human hair is about 60-75 microns in diameter.

Particles under 35 microns in size can't be seen with the naked eye. Pollen is in the 10 -100 micron size range with dust in the 0.5 - 5 micron range. Particles under the 5 micron size are the most troubling for asthmatics since that is the ideal size to penetrate deep into the lungs.

Examples of some common air contaminants and their size in microns:

Human Hair ......................................... (70 - 100 microns)
Human Sneeze .................................... (10 - 100 microns)
Pet Dander .......................................... (0.5 - 100 microns)
Pollen ................................................. (5 - 100 microns)
Spores from Plants .............................. (6 - 100 microns)
Mold.....................................................(2 - 20 microns)
Smoke .................................................(.01 - 1 micron)
Dust Mite Debris ................................. (0.5 - 50 microns)
Household Dust ................................. (.05 - 100 microns)
Skin Flakes ...........................................(0.4 - 10 microns)
Bacteria................................................(0.35 - 10 microns)

IAF provides variety of HEPA FILTERS to fulfill the market requirement.

ALUMINIUM SEPARATOR HEPA FILTERS

The IAF- HEPA (Aluminum Separator) filter is constructed with 20 gauge powder coated mild steel frame with a continuous band of media pleated back and forth over corrugated aluminum separators. These filters contain a two-part polyurethane, which assures a positive seal of the media pack and frame. The interlocking frame design with sealant placed behind the top and bottom flange allows unobstructed air flow and ease of filter handling.

MINI PLEAT HEPA FILTERS

The IAF mini pleat filters are manufactured in European technology machine with highest accuracy and quality.

The IAF mini pleat Filters Squeeze maximum filtration into a 2-inch or 4-inch filter track or frame. The mini pleat incorporates all of the best in filtration technology. The media area is five times as compared to a standard pleated panel filter, Mini Pleats last longer and offer higher efficiency. The media is a single web of gradient density fibers which achieves high dust holding, high efficiency and low pressure drop. The pleats are held rigid and evenly spaced to maintain even loading and air distribution. The Mini Pleat is light weight and can be totally incinerated.
