HEPA (High Efficiency Particulate Air) and ULPA (Ultra Low Penetration Air) filters are the most efficient air filters commercially available. Originally developed in the 1940’s and 1950’s by the U.S. Army Chemical Corp, Naval Research Laboratories and Atomic Energy Commission, HEPA filters have a minimum efficiency of 99.99% for particles down to 0.3 microns.
Due to the fragile construction of HEPA / ULPA filters LAF Technologies recommend that only trained professionals install these types of filters.
Improper installation can cause irreparable damage and non-compliance during testing (AS 1807.6). At LAF Technologies Pty Ltd we are able to supply, install, test and NATA certify to 99.99% DOP challenge almost any size filters (including holding plenums) to suit your installation.
