Fume Removal System for Laboratories with Consistent Velocity

A Bypass Chemical Lab Exhaust Hood is an efficient fume removal system for laboratories. Continuous air flow across the work surface of the Bypass Chemical Lab Exhaust Hood exhausts potentially hazardous vapors safely away from the work environment, even with the sash closed. The Bypass Chemical Lab Exhaust Hood features an internal bypass opening located above the sash opening allowing for a constant exhaust volume while maintaining the face velocity. In operation, the bypass adjustment is made as the sash window is opened and closed creating a relatively constant face velocity regardless of sash position. (Lab Fume Hoods Images)

The Bypass Chemical Lab Exhaust Hood comes equipped with a full view sash providing an unobstructed view of the hood interior work area. The sash, a glazed 7/32” thick laminated safety glass, is provided with a full width flush pull. A counterweight provides for one finger operation of the sash at any position.

The entrance of the Bypass Chemical Lab Exhaust Hood is framed with inward-angled members. This angled frame works to minimize turbulence and provide smooth operation of air into the Bypass Chemical Lab Exhaust Hood, resulting in a more efficient operation of the hood at face velocities ranging from 60 to 150 FPM. A lower airfoil sash stop maintains a 1” space (below closed sash) that allows air to flow continuously across the work surface inside the Bypass Chemical Lab Exhaust Hood.

Bypass Chemical Lab Exhaust Hood Superstructure and Lighting

Double wall construction of the Bypass Chemical Lab Exhaust Hood’s superstructure allows for easy installation of service fixtures and routing of interior plumbing and electrical lines. The interior of the Bypass Chemical Lab Exhaust Hood is white resin-chem. Removable access panes on both interior sides of the Bypass Chemical Lab Exhaust Hood are standard features. The exterior superstructure side panels are also removable for easy access to service fixtures and supply lines.

A maximum width, two tube fluorescent light fixture, complete with tubes, is provided with the Bypass Chemical Lab Exhaust Hood. The light fixture is mounted above a sealed safety glass panel, which isolates it from corrosive fumes and hazardous vapors. Tube lights are easily replaced through the top front of the Bypass Chemical Lab Exhaust Hood’s superstructure.
