Bypass Fume Hoods

LOC’s basic concept for fume hoods revolves around safety and performance.

Even with the sash closed, potentially hazardous vapors are kept away from the work environment as a result of continuous air flow across the work surface. Internal bypass opening, located above the sash, allows a constant exhaust volume while maintaining the face velocity. In operation, the bypass adjustment is made as the sash is opened and closed, creating a relatively constant face velocity regardless of sash position.

Design Elements:

• Equipped with a full view sash providing an unobstructed view of the hood interior
• Sash is 7/32" laminated safety glass with full width flush PVC pull and spring loaded sash stop
• Counterweight provides a 1-finger sash operation
• Hood entrance is framed with inward-angled members to minimize turbulence and provide smooth air movement in hood at face velocities ranging from 60 to 150 FPM
• Stainless steel airfoil allows 1" of airflow across the work surface when sash in in the closed position
• Double wall construction for ease of routing plumbing/electrical lines
• Standard "Resin-Chem" interior liner with removable access panels on both sides
• Removable exterior side panels
• Maximum width, two tube fluorescent light fixture complete with tubes is provided
• Light is mounted above a sealed safety glass panel keeping corrosive fumes and hazardous vapors isolated
• Tube lights can easily be replaced through the top front

All fume hood models are tested with the ASHRAE 110 Test at the factory.
