Chapter 2: Prerequisites
Location Requirements
The 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 fume hood on a
cart, dolly, or mobile bench. ALL
Fiberglass 30 Hood installations must
be permanent and stationary. The
supporting structure usually consists
of a base cabinet and chemically
resistant work surface. See Chapter 7
Modifying Your Fiberglass 30 Hood.
Exhaust Requirements
The exhaust duct connection has been designed for 6"
nominal duct (6.625" OD) to allow for minimum static
pressure loss while operating at 100 fpm face velocities.
The 6" 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:
Fiberglass 30 Hood with Integral Blower, 100 fpm, 310
cfm, capable of overcoming 0.12" external static
pressure.
Fiberglass 30 Hood for use with Remote Blower, 100
fpm, 310 cfm, 0.14" static pressure loss.
Fiberglass 30 Hood with Explosion Proof Blower, 100
fpm, 310 cfm, capable of overcoming 0.12" external
static pressure.
Proper blower selection can be determined from these
exhaust requirements and the total system static
pressure loss. Contact Labconco Customer Service for
assistance in sizing a blower.
