Over time the HEPA filter will load and eventually slow 
the downflow velocity.  Once the alarm condition is met, 
simply increase the speed control as outlined in Chapter 6 
or replace the HEPA filter if the speed control is 
maximized. 

7.

 

The table below lists typical alarm conditions based on 
normal operating conditions.  Typical alarm conditions are 
set at downflow velocities of 10 to 30 feet per minute 
below the normal operating conditions due to supply air 
and exhaust air fluctuations, as well as room air cross 
drafts.  Consult your Safety Officer or Laboratory Manager 
for proper operating speeds.
