UniFlow CE Fume Hood0 pages

CE Laboratory Fume Hoods
Full duty fume hoods in space and energy saving sizes of 30”, 36”, 48”, & 72” widths. UniFlow CE models are
low ow constant volume fume hoods that require no VAV controls, no motorized bafes, no costly auxiliary air
system and no special integral supply fans. These units can save 50% or more in costly exhaust volume
typically required to operate a conventional fume hood. Fume hood is U.L.1805 classied.

Access Panel removable to access ducting
connections, plumbing & electrical services from
a single point electrical box,115V/60Hz AC operation. Energy efcient T-5 two-bulb vapor proof
uorescent light xture with polished stainless steel
reectors, and light switch on left column, all factory
installed.
Full 27” Viewing Height for ease of access
and unobstructed view of fume chamber while
working with tall apparatus and distillation grids.
Air Flow Monitor continuously monitors face
velocity airow, analog or digital available. Meets
ANSI and OSHA requirements. See page 37.

Vertical Sash to be counterbalanced connected
with coated stainless steel cables, 3/16” tempered
safety glass with chemical resistant non-metallic
PVC framing track and aerodynamic sash lift.
VaraFlow Bafe System maintains uniform
airow thru the VaraFlow bafe system to bell shaped
exhaust collar outlet.
Ergonomic Sash Lift contoured for efcient
airow and ease of movement.
22” Sash Height for viewing of fume chamber,
loading and unloading equipment for set up.

Angled Picture Frame Opening The

aerodynamic face opening with air foil provides uniform
air ow into the fume chamber and thru the VaraFlow
bafe system to the bell shaped exhaust collar.

Sash Stop located at 1/2 open to reduce
airow 50%, standard equipment.

SASH MANAGEMENT 1-2-3
1. Cut energy costs up to 50%. For improved lab efciency
air ow monitors check the fume hood face velocity &
help to insure that the proper amount of room air changes
per hour are maintained. The sash stop is designed for
user protection and cfm reduction, allowing the sash to
open to a maximum position of half open. With an average
utility rate of $7.00 per cfm a typical annual savings on a 4’
fume hood would be $2705.00 on a 6’ fume hood $4067.00.
2. Sash should only set to full open position for the set up
of tall apparatus. Personal safety protection should
be worn as recommended by the Lab Safety Ofcer.
3. When the fume hood is not in use return the sash to the
closed position.

Fume Hood Face Velocity cfm
The recommended face velocity for efciency &
safety should be 80-100 fpm. Lower face velocity
may compromise user safety.
Sash in full open position should be for setup of
apparatus & maintenance service only. If opening
is at 1/2 open at 100 fpm (feet per minute), face
velocity at full open would be approximately 50
fpm.
