Chapter 2: Prerequisites
Location Requirements
The floor-mounted fume hood should
be located away from traffic patterns,
doors, windows, fans, ventilation
registers, and any other air-handling
device that could disrupt its airflow
patterns. All windows in the room
should be closed.
Support Requirements
DO NOT install the floor-mounted
fume hood on a cart, dolly, or mobile
bench. ALL Protector XL Floor-
Mounted Hood installations must be
permanent and stationary. The hood
is usually mounted directly on the
room floor surfaces, or on an optional
chemical resistant work surface.
Exhaust Requirements
The exhaust duct connection has been designed for 12"
nominal duct (12.75" OD) to allow for minimum static
pressure loss while operating at 100 fpm face velocities.
The 12" diameter exhaust duct also allows for proper
transport velocities away from the hood in the 1000
fpm to 2500 fpm range. The proper exhaust volume
and static pressure loss are listed next for each hood
model:
