Original instructions
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.
La hotte aspirante devrait être localisé loin des voies de
circulation, des portes, des fenêtres, des ventilateurs, des
bouches de ventilation, et de tout appareil qui pourrait
interrompre ses voies de flux d'air. Toutes les fenêtres dans la
pièce devraient être fermées.
Support Requirements
DO NOT install the fume hood on a cart, dolly, or mobile
bench. ALL Protector Hood installations must be permanent
and stationary. The supporting structure usually consists of a
base cabinet and chemically resistant work surface.
NE PAS installer la hotte aspirante sur un chariot ou un banc
mobile. TOUTES les installations de la Hotte Protecteur
doivent être permanentes et fixes. La structure de soutien
consiste habituellement en un meuble doté d’une surface de
travail chimiquement résistante.
Exhaust Requirements
The exhaust duct connection has been designed for 11" nominal duct (11.00" OD)
to allow for minimum static pressure loss while operating at 100 fpm face
velocities. The 11" diameter exhaust duct also allows for proper transport
velocities away from the hood in the 1000 fpm to 2500 fpm range. The exhaust
duct used in conjunction with the Perchloric Acid Fume Hood should be
fabricated out of Type I, unplasticized PVC or Type 316 stainless steel. Stainless
steel ducting must require that it be fully welded in place so that it does not allow
any cracks or holes at the joints to allow for the collection of Perchloric acid. The
proper exhaust volume and static pressure loss are listed next for each hood
model:
