State-of-the-art filter 

At the heart of the EDU Series product line is innovative carbon filtration technology. The Multiplex Filtration System consists of a pre-filter, main activated carbon or HEPA/ULPA filter, and safety activated carbon or HEPA/ULPA filter. The system permits a customized combination of filter media and configuration for chemical and physical adsorption specific to each application need. The Air Science carbon filtration technique is based on enhanced, activated carbon particle formulations from specially selected, naturally occurring raw material that is superior to wood or other organic sources. The carbon is treated to attain the proper porosity and aggregate surface area and to react with several ranges of aerosolized chemicals moved through the filter by an air handling blower. 

Enhanced filtration

Air Science® ductless fume hoods isolate and trap chemical vapors to prevent ecological impact through release into the environment. 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 EDU series ductless fume hoods.

Multiplex Filtration technology

At the heart of the EDU Series product line is innovative filtration technology. The Multiplex Filtration System consists of a pre-filter, main activated carbon or HEPA/ULPA filter, and safety activated carbon or HEPA/ULPA filter. The system permits a customized combination of filter media and configuration for chemical and physical adsorption specific to each application need. The Air Science carbon filtration technique is based on enhanced, activated carbon particle formulations from specially selected, naturally occurring raw material that is superior to wood or other organic sources. The carbon is treated to attain the proper porosity and aggregate surface area and to react with several ranges of aerosolized chemicals moved through the filter by an air handling blower. 

The Multiplex feature permits one or more filtration options to be combined to meet a wider range of multiple-use applications. The EDU Fume Hood can be equipped with a single activated carbon main filter or with a stacked configuration which combines two main filters, each activated to adsorb one or more specific vapors or family of vapors. For safety against particulates, an optional HEPA or ULPA can also be added. When used with a HEPA/ULPA filter, the ductless fume hood may be applied as a Class I Biological Safety Cabinet. The carbon filter is sized to fit the specified product model number and configured to optimize airflow across 100% of the filter surface area. The self-contained assembly maximizes filter efficiency, prolongs filter life, optimizes diffusion and saturation, and improves user safety.

P.   Electrostatic Pre-Filter: Protects the main filters from aerosols, mists, dust, and particulates.

C. Activated Carbon Main Filter: A single, blended, or stacked filter configuration.

H. HEPA/ULPA Filter, Optional: Both HEPA and ULPA filters use micro-glass fiber media designed to capture fine particles and biologicals. Both filters can capture particles smaller than the micron size for which they are tested. HEPA and ULPA filter efficiencies are 99.995% at 0.3 microns and 99.9995% at 0.12 microns respectively.

Each filtration system is selected for its specific application. Carbon filters are available in more than 14 configurations for use with vapors of organic solvents, acids, mercury, and formaldehyde. 

HEPA/ULPA filters can be added for biological safety.

Easy to Install

The ductless fume hood is self-contained and does not require venting to the outside. Many units are portable and may be moved with minimal downtime and without filter changes. Set-up, operation, and filter maintenance are straightforward. 

Energy Efficient

Because filtered air is returned to the room, no demands are required of the facility HVAC capacity for make-up air. 

Cost Effective

Facility ductwork, HVAC, and construction costs are eliminated.

Safe to Use

Cabinet airflow and face velocity protect users from incidental exposures to fumes. 

Self-Testing (select models)

Electronic airflow monitoring assures continuous safety. An electronic gas sensor monitors carbon filter performance.

Biosafety cabinet airflow requirements met and exceeded

Air Science Multiplex Filtration offers a range of options for high performance protection.Multiplex filter configuration permits a customized combination of filter media for a broad range of chemical families and biological agents if required. EFT™ filtration technology broadens the Air Science application for ductless fume hoods. A high capacity air handling system delivers face velocity of 100 fpm. EDU Series fume hoods maintain a constant face velocity of 100 FPM in compliance with U.S.A. and International standards for safety and performance. Contaminated air is pulled through the Multiplex filtration system where activated carbon adsorbs chemical vapors, returning clean air to the room.The main filters are easy to replace; no tools required. The filter clamps tightly against the filter gasket to prevent filter bypass and to maintain filter integrity.

Fume hood competition comparaison

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 (isoproponal, 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.
