Description
Terra's Ductless Exhaust Fume Hoods provide safe removal of a broad range of organic chemical fumes without the
need for cumbersome ductwork.
These high-capacity hoods feature dual 3000-RPM impellers (each rated for 740 CFM @ 0" static pressure) to ensure
a safe exhaust flow speed of 100 fpm under filter load. Bonded activated charcoal filters eliminate voids in the filter
medium and minimize particle sloughing. For cleanroom operation, an exit HEPA filter, rated 99.99% efficient @ 0.3-
micron particle size, may be specified.
Terra's standard model (No. 2900-20) is ideal for most benchtop applications. The all-polypropylene construction is
resistant to most chemicals. This model features a built-in air Vaneometer™ Air Velocity Meter for easy monitoring of
the exhaust air speed.
Terra's High-Clearance Chemical Fume Hood (Nos. 2900-30 through 2900-33) provides over 28" of vertical clearance
with the access shield open, making it ideal for distillation and other operations with large glassware or equipment. It
is available in several hood materials and includes a spill tray made of white polypropylene.
Vapor-Sealed, Fluorescent Lighting
In order to avoid potential fire or explosion hazards, the Ductless Exhaust Fume Hood includes vapor-sealed lighting
as a standard light fixture.

Installation
Carefully uncrate the Ductless Exhaust Fume Hood and visually inspect for damage. Any damage should be reported
according to the procedures outlined in the shipping agreement.
The hood is normally shipped fully assembled, with filter(s) installed inside the filter housing and both filter and blower
housings securely clamped in place.
To operate the unit, simply place the hood on a sturdy, level work surface, plug the blower power cord into a
grounded 115/230VAC, 50/60Hz power source, and turn it on (the blower must be ordered for the proper voltage
supply).
