OEM All PP Gas Extractor Ductless Fume Hood for Chemistry

Ductless fume hoods contain filters which clean contaminated air and recirculate it directly back into the laboratory. No additional ductwork is required to exhaust air to the outside. Ductless fume hoods provide the same filtration capabilities as ducted hoods, but are easier to install, have lower initial installation costs, can easily be moved or relocated in the laboratory and can be highly efficient.

• Compliance to ASHRAE 110 for superior fume containment
• Effective carbon filtration efficiency
• Easy-to-use control system with alarms for unsafe conditions
• Wide selection of carbon filter types to accommodate a variety of chemical handling
• Plug-and-play feature which prevents any laboratory downtime
• Offers a broad range of accessories and options
• Industry-unique dual diffuser system that helps optimize carbon filter life
• Energy-efficient design which reduces total carbon footprint
• Must be mobile, portable, and easily relocated

Advanced ductless carbon filtration technology offers a safe, high performance alternative to conventional ductless fume hoods for a broad range of applications.

• Environmental Benefits. Air Science ductless fume hoods isolate and trap chemical vapors to prevent ecological impact through release into the environment.
• Versatile. Each filtration system is selected for its specific application. The Multiplex Filter broadens the range of applications. Carbon filters are available in more than 14 configurations for use with vapors or organic solvents, acids, mercury and formaldehyde. HEPA/ULPA filters can add to biological safety.
• Easy to Install. Fume hoods are self-contained and do not require venting to the outside. Many units are portable and may be moved from one location to the next 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. (selected models) Electronic airflow monitoring assures continuous safety. An electronic gas sensor monitors carbon filter performance.

Fume hoods have been used in laboratories for generations. In fact, some historians credit the first fume hood to either Thomas Jefferson or, later, Thomas Edison both of whom are said to have used the natural draft of a fireplace and flues to exhaust unwanted vapors during experiments. It was, however, Joseph Priestly who created the first laboratory chemical exhaust hood in 1790. With the introduction of electricity and electrical engineering, the invention of the first blower motor paved the way for fume hoods as we know them today. In 1923, the first ducted fume hood was installed at the University of Leeds, UK.

The introduction of HEPA filters in the 1950s opened the doors to ductless fume hood varieties which have been in use in a variety of laboratories for more than 40 years. Since that time, cabinets have gone through a number of changes that have expanded the applications they serve.
