HEGA filters are most often used for containment of toxic gases in air filtration systems. A HEGA collects gaseous contaminants from an airstream through adsorption. With a properly designed system, any adsorbable contaminant can be filtered and contained. All HEGAs are factory tested to a minimum mechanical efficiency of 99.9 percent.
Camfil Airepure provide specialty HEGA (High Efficiency Gas Adsorption) filters are manufactured from the highest quality of materials under strict quality control conditions as custom targeted high mass carbon media installed into V-bank style housings, and are factory tested to meet the requirements of IES RP-CC-008- 84, Recommended Practice for Gas Phase Adsorber Cells.
HEGA filters are commonly used in conjunction with HEPA filters in high efficiency exhaust BIBO (bag/in-bag/out) airborne containment systems or radioactive dispensing / cyclotron areas. They are typically type tested and media is batch tested. Where required, field testing to confirm performance can be undertaken. The primary thing to consider is the handling of these filters they are bulky and extremely heavy due to their construction and carbon mass.
