CRITI-CLEAN ULTRA FAN FILTER UNIT

NETWORKING

When networking the fan filter units either in a local area network (LAN) or connecting to

a BAS/BMS system, each unit is connected in a "straight-through" daisy-chain using  Cat5e or 

Cat6 network cables and the on-board RJ45 connectors.

If field cutting network cables, it is important for each end of the cable to be wired identically.

 However, assembled network cable are available; field assembled cables are the leading

cause of problems in new systems.

ACC1001 control used

as an example.  Other 

controller options

available.

Power supply board

can be located in the 

lead FFU or in the controls

enclosure.
