Purair Basic Ductless Fume Hood, 36", Extra Tall, Standard Footprint. Advanced carbon filtration technology offers a safe, high performance alternative to conventional ducted fume hoods for a broad range of applications. These fume hoods isolate and trap chemical vapors to prevent ecological impact through release into the environment. 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. HEP/ULPA filters can add to biological safety. This ductless fume hood is easy to install. It is self-contained and does 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. They're also cost effective and safe: facility ductwork, HVAC and construction costs are eliminated. Cabinet airflow and face velocity protect users from incidental exposures to fumes.

Order filters separately. Requires one main filter. This product exceeds OSHA, ANSI and other international standards. Purair® Basic ductless fume hoods are a series of high efficiency products designed to protect the user and the environment from hazardous vapors generated on the work surface. At the heart of the Purair fume hood product line is the innovative Air Science Multiplex Filtration Technology that creates a safe work environment over the widest range of applications in the industry.

Purair Ductless Fume Hood Purair® P5-36, shown with Multiple x Filtration System.

The Purair® Basic Series ductless fume hood maintains a constant face velocity of 100FPM in compliance with USA and international standards for safety and performance. Contaminated air is pulled through the Multiple x filtration system where activated carbon adsorbs chemical vapors and/or particulates if HEPA/ULPA filters are used. Clean air is returned to the room.

The main filter is easy to replace, no tools required. The filter clamps tightly against the filter gasket to prevent filter bypass and maintain filter integrity.

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

  • Professional Quality. Air Science® fume hoods comply with current technical and safety regulations.
  • Multiple x Filtration. The Air Science® 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.


Purair® Basic products are available in 3 standard sizes, each with 4 configuration options and metal or polypropylene construction, totaling 24 standard models.

  • High capacity air handling system delivers face velocity of 100 fpm.
  • A low airflow alarm warns of insufficient face velocity.
  • The Air Science® filter assembly is easy to access, easy to change.
  • A unique filter clamping design eliminates bypass leakage outside the cabinet.
  • Accessories include an optional filter saturation alarm.
