3.4 Instrumentation Ports
The instrumentation ports with threaded closures are located on the doors of the chamber. The
ports enable instrument probes, and small hoses, etc. to be passed through the wall of the cabinet
for connection to equipment within the cabinet growth environment.
3.5 Fresh Air Inlet and Exhaust Ports
The fresh air inlet allows the operator to manually adjust the rate at which fresh air is introduced
into the chamber. The threaded collar is located on the front of the machine compartment and can
be adjusted from fully closed (no fresh air) to fully open to allow up to 55 ft
3
/min (1.55m
3
/min) of air
exchange.
The fresh air inlet assembly contains a foam filter to help prevent dust and larger particulate
matter from entering the growth area. This filter should be cleaned monthly to prevent a build-up
of foreign material that could restrict airflow.
Fresh air is drawn into the front of the chamber through the intake port located in the machine
compartment and then exhausted through the exhaust port (Figure 3-4). An optional variable
speed fan is available.
