Radioisotope 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.
