Add Air Fume Hoods

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

The LOC Airfoil Add Air Fume Hood provides added economy through the use of a front mount “add air plenum” that can supply up to 70 percent of the total hood air volume required from an outside source.

Design Elements:

• Built-in bypass works to maintain a relatively constant face velocity at any sash position
• Front mounted add air plenum utilizes diffusers and louvers to allow a uniform flow of supply air
• Provides up to 70% of the overall air volume requirements
• 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 one finger sash operation
• Includes audible LOC200 airflow monitor for safety
• 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 is 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 panel keeping corrosive fumes and hazardous vapors isolated
• Tube lights can easily be replaced through the top front
• LOC's basic concept for fume hoods revolves around safety and performance

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