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:
Compatible Models: NU-475 / 477 / 480 / 481
Combine with NU-AIN-315BSC low flow exhaust monitor to comply with Standard NSF/ANSI 49.
