Chapter 3: Getting Started
Sealing the Protector XL
Floor-Mounted Hood to the
Floor
When the hood has been set in place, ducted, wired, and
plumbed, it should be sealed to the floor to prevent
spilled materials from collecting under the walls of the
hood. Materials such as silicone sealants are
recommended to seal the hood structure.
Certifying the Protector XL
Floor-Mounted Fume Hood
The combination of your laboratory hood, exhaust
ductwork, and exhaust blower gives you the flexibility
to change the airflow at the sash opening of your hood.
To determine the actual face velocity at the sash
opening, airflow velocity readings will need to be
taken. This should be done across the sash opening of
the hood in accordance with the Industrial Ventilation
Manual section on laboratory hoods. (See Appendix D
– Reference) Labconco recommends an average face
velocity at the sash opening of 80 to 100 feet per
minute. Consult Labconco Customer Service for proper
airflows for your particular model.
Your Protector Fume Hood has been tested at the
factory per ASHRAE 110-1995. All hoods achieve an
“as manufactured rating” of less than 0.10 part per
million (ppm) at 4 liters per minute (lpm); AM<0.10
(consult Labconco for individual fume hood ratings).
For “field use” ASHRAE testing contact Labconco
