Fixed Range Transition

The NU-907 Fixed Range Exhaust Transition provides an air gap between the exhaust efflux of the BSC and the transition. The air gap essentially insulates the BSC from potential variations of airflow in the plant exhaust system, particularly if multiple BSC's are connected to the same exhaust blower system. NuAire's canopy employs a one-inch air-gap with a recommended minimum airflow through the gap of 175 LFPM (.89 m/s) nominally 200 LFPM (1.016 m/s). The characteristics of Canopy Transitions are as follows:

• Preserves airflow balance within the BSC in a simple dependable manner.


• Has a removable front service panel to permit exhaust HEPA filter integrity checks.


• Simplifies exhaust system design.


• Should be used with an adjustable exhaust system or damper to balance airflow and limit the loss of conditioned air from the room.


• Provides a safety operational tolerance range for exhaust system fluctuations ranging from no exhaust to 15% above total CFM required (BSC exhaust CFM plus air gap CFM).
