EFT™

The Advantage of Air Science Enhanced Filtration Technology (EFT™)

The Air Science Enhanced Filtration Technology (EFT™) is a universal filtration system developed for use with a wide range of core chemical families. These include organic acids, alcohols, aliphatic hydrocarbons, aromatic hydrocarbons, esters, aldehydes, ketones, ethers, halogens and others. Although the EFT system is weighted to accommodate these families, it can handle inorganic acids as well.

The Air Science EFT system is available as an option on Air Science Advanced ductless fume hoods and the Air Science Purair Eco Series fume hood. The EFT™ option can be retrofitted on many Air Science ductless fume hoods already in service worldwide.

Independent Test Results

Independent testing confirms that the Air Science EFT™ system is superior in critical areas to other “green” fume hood systems recently introduced to the industry. AFNOR NFX 15-211 requires that three chemicals - isopropanol, cyclohexane and hydrochloric acid - be tested under very precise conditions to ascertain and establish retention capacity at 1% of the threshold limit value (TLV) for each chemical.

*Based on “core” chemical families typically used in ductless fume hood applications, the Air Science EFT™ filter offers significant advantages over filters marketed as “universal” filters. On inorganic acids the EFT™ filter provides a lesser but more realistic usable capacity in that with moderate to heavy acid applications, all ductless fume hoods made of metal are subject to corrosion and rust. In those applications Air Science recommends its polypropylene or total exhaust hoods with a specially formulated heavy duty acid filter.
