 Canopy Exhaust Connection 
Certain applications such as working with odorous products or volatile toxic 
materials will require the connection of the Procedure Station to an exhaust 
system. 
Note: The canopy connection, also referred to as a thimble or air gap 
connection, allows single or multiple stations to be connected to an exhaust 
system. During operation, the exhaust system draws all of the cabinet’s 
exhaust air, plus a volume of room air (through the vent in the canopy) into 
the exhaust duct. Canopy connections function as a “shock absorber” 
allowing the system to function properly during changes in room air pressure. 
For information on selecting a canopy connection, go to Appendix D: 
Accessories. 
Note: If the research involves the use of toxic compounds or volatile 
materials, contact the facility’s safety officer or Labconco to ensure that the 
Procedure Station and its exhaust system are compatible with the materials 
you will be working with.
