Southern Coastal Machinery is proud to introduce a new series of machines for the production of HEPA Filter Media. These systems produce micro-fiber electrostatic charged media that is tailored for use in the manufacture of HEPA filters. Our supplied HEPA media Meltblown machine is made in the USA from high grade materials and components.
What is a HEPA Filter and How Does it Work?
HEPA filters have a wide range of applications, from low tech applications such as the exhaust system of a vacuum cleaner to high tech applications where they are used in “clean rooms.” HEPA filters will trap particles as small as 0.3 microns, including many allergens, bacteria, and viruses.
HEPA Filter Specifications
HEPA is a type of pleated mechanical air filter. It is an acronym for “high efficiency particulate air [filter]” (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mould, bacteria, and any airborne particles with a size of 0.3 microns.
They are typically installed into the HVAC system in buildings and consist of a series of filter housings containing pleated Meltblown HEPA filter elements. The air that passes through them is filtered of microscopic dust and debris that can damage equipment and health.
Why 0.3 microns?
That micron size (0.3) is referred to by scientists as the MPPS, or the most penetrating particle size. Scientists have found that particles of that size evade air filters more than larger or smaller particles.
What is a HEPA filter made from?
Previously, HEPA filters consisted of micro-glass fiber mats that were typically created by a wet-laid web forming process. However, glass fibers are themselves a fibrinogen and can be quite dangerous if released from the wet laid web into the air stream. For this reason, an effort has been made to find an alternative to glass. Now, with our latest nano-fiber meltblown process along with electrostatic charging, SCM has created an improved filter media with reduced health risks.
HEPA Filter Market
HEPA Filter was commercialized in the 1950s, and the original term became a registered trademark and later a generic trademark for highly efficient filters. HEPA filters are used in applications that require contamination control, such as the manufacturing of hard disk drives, medical devices, semiconductors, nuclear, food and pharmaceutical products, as well as in hospitals, homes, and vehicles.
Activated Carbon HEPA Filter
Activated carbon can also be introduced into the HEPA filter media which can eliminate odors, aerosols and smoke. Southern Coastal Machinery has recently been awarded a US Patent for our process of impregnating meltblown filter media with activated carbon as well as other particulate material. US Patent Number 9,981,211.
