Ventilated Balance Enclosures
Low Velocity Fume Hoods
The PLAS-LABS’ HEPA filtered ventilated balance enclosures are the latest in self contained laboratory processing products. The VBE Series is ideal for workingwith fine powders, and chemical and biological products.
These portable ventilated balance enclosures include top mounted HEPA/Blower filtration. They are set-up to circulate the internal atmosphere into the lab, attach to our 900-EXTRACT Extraction Unit, or attached to your house exhaust system.
The smooth curved, or rounded, ABS™ airfoils provide gentle, unobstructed air flow through rear baffles and through the top mounted HEPA filter.
The ventilated balance enclosure provides minimal laboratory space and minimal energy usage.

Most Popular Accessories
Bag-In / Bag-Out Port
800-BIBO/PORT, Bag-In / Bag-Out port includes a long ArmorFlex TM polypropylene bag (48” long) for safe removal of trash and unwanted debris.
Unwanted debris and trash are always contained and are never exposed outside of the containment isolator. Bag port is 6” OD clear acrylic with two machined grooves for bag placement.
Bag Port Crimper Tool
The 800-BIBO/CRIMPER allows you to safely and securely remove, and seal, used HEPA filters. HEPA filters are removed from the inside of the glove box, through the transfer chamber, and into the Bag-In / Bag-Out port. The used HEPA filters are never exposed to the laboratory atmosphere or the researcher.

Low Velocity, non-HEPA filtered Fume Hoods
This Low Velocity Fume Hood system has been developed in response to customer requests and suggestions for improvements to the original product currently offered in the market place.
These units can be used with your in-house exhaust system or our accessory #900-EXTRACT, Fume Extraction Unit. All units are ANSI/ASHRAE 110:2016 Certified. You can select either HEPA or Activated Carbon filters (or a combination of both) for the Extraction Unit. Three (3) styles of Carbon are available.
900-LFVH/36
900-LVFH/24
All Low Velocity Fume Hoods include:
- Standard 24 month warranty (Not consumables; i.e. filters).
- Units are fabricated out of .375” (9.5 mm) thick optically clear acrylic plastic.
- Hinged (two [2] position) front sash with draft deflector.
- Formed horizontal lower front airfoil.
- Two (2) formed vertical air foils with draft deflectors.
- Bright white acrylic bottom work surface.
- Two (2) side wall cable ports at 1.5ӯ (38 mm).
- Six (6”) inch Ø (about 152 mm) exhaust hook up.
- The exhaust hose is smooth bore inside and is six (6”) inch (152mm) Ø x eight (8’) feet (2,440 mm) long.
Our hoods are unique in that they include both horizontal and vertical “air foils” taking advantage of a“venturi” effect. They also feature rounded rear corners to guide and facilitate inner atmosphere exhaust efficiency.
The exhaust hose has a “smooth bore” interior, which minimizes air flow exhaust restrictions, is chemically resistant, FDA approved, and is included with the main work housing. It may be attached directly to your house exhaust system.
