2.2 Enclosure Internals
A. Compression Conveyor
B. Upstream and downstream height adjustment
C. Sampling points
2.3 Enclosure Purge
The enclosure purge fan is located at the top of the system enclosure. When in use it can
direct up to 120 CFM of air into the enclosure. Inside the enclosure 2 deflection plates
direct the airflow to the upstream and downstream side of the system.
The net effect is a slight positive pressure is created inside the enclosure which prevents
ingress of contaminated air. If uncontaminated air needs to be ducted in from another
source then this can be done with the 100mm duct fitting on top of the purge fan.
2.4 Reject Station
The reject station is located after the compression conveyor and has 3 modes of operation:
1.
Normal – in this mode any packs identified as a reject will be automatically
rejected at this point with a blast of compressed air.
2.
Clean – in this cleaning mode the system rejects all packs detected. (As
nominally no packs should be present during cleaning procedures)
