Advanced Application Ductless Fume Cabinets / Fume Hoods

Enhanced Filtration Technology (EFT™)

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 Purair Advanced ductless fume cabinets, standard on Purair Eco Series fume cabinets, and can be retrofitted on many similar brand ductless fume hoods already in service worldwide.

The Purair Performance Advantage

Each fume cabinet includes features expressed through sound design and certified quality construction. Options and accessories add functional performance to meet specific applications.

• Professional Quality. Purair fume cabinets comply with current technical and safety regulations.
• Multiplex Filtration. The Multiplex™ Filter offers a range of options for high performance.
• Industrial Components. The cabinet frame and work surfaces are durable and chemically resistant.
• Reliability. Internal systems are isolated from fumes, extending product life.

Independent Test Results

Independent testing confirms that the EFT™ system is superior in critical areas to other “green” fume cabinet / 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.

The Multiplex filter configuration permits a customised combination of filter media for a broad range of chemical families and biological agents if required. EFT™ Filtration Technology broadens the application for ductless fume cabinets.

Purair® AirFlow Pattern

Purair 20, shown with Multiplex Filtration System.

The Purair Series ductless cabinet / fume hood maintains a constant face velocity of >0.50 m/s in compliance with Australian and international standards for safety and performance. Contaminated air is pulled through the Multiplex filtration system where activated carbon adsorbs chemical vapours; clean air is returned to the room.

A. The main filter is easy to replace, no tools required. The filter glides in on a wheel and track system, then clamps tightly against the filter gasket to prevent filter tears and maintain filter integrity.

*Based on “core” chemical families typically used in ductless fume cabinet / hood applications, the 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 the Purair manufacturer recommends its polypropylene or total exhaust cabinets with a specially formulated heavy-duty acid filter.
