Variable Air Volume Fume Hoods
The Variable Volume Fume Hood is specifically
designed for use with exhaust control systems provided by other
manufacturers that monitor and control the amount of air being
exhausted from the Hood. The use of these devices will maintain
a constant face velocity and greatly reduce the operating cost
of the Fume Hood.
Design
A lintel at the upper front of the superstructure restricts the
Hood air intake to the front sash opening. By incorporating any
one of a number of commercially available VAV controls, the
exhaust volume of the Hood can be varied to maintain a specified
face velocity regardless of sash position.
The full view sash provides a clear, unobstructed view of the
work surface and when fully opened, allows easy access to all
areas of the Hood interior. The sash is counterweighted for easy
up/down operation and is made of 7/32" laminated safety glass
with a full width flush pull.
The lower airfoil acts as a sash stop designed to provide a 1"
gap (with sash closed) allowing air to continuously sweep the
countertop of the Fume Hood.
Double side wall Hood construction provides adequate space for
mounting service fixtures. The interior "Resin-Chem" lining has
removable access panels on either side providing easy access for
installation and maintenance of service and electrical fixtures.
Both exterior side panels of the Hood superstructure are also
removable for access to lines.
Interior Lighting
A twin tube fluorescent light fixture provides illumination of
the Hood's interior surfaces. The fixture is recessed into the
interior Hood ceiling and protected behind a sealed safety glass
panel away from hazardous vapors and corrosive fumes. Tubes
(included with Hood purchase) are easily replaced from the
outside of the Hood superstructure.
Options
A variety of optional service fixtures are available from LDS
for installation in the Variable Volume Fume Hood. Mounting
holes for fixtures and electrical receptacles are pre-cut and
capped when fixtures are not required.
