Manual Control The manual butterfly valve incorporates a lockable handle to open and close the valve. The heavy duty, PVC covered handle consists of a pointer to indicate percent open and setscrew to lock the damper in position. - 14 gauge, Type 304 Stainless Steel Construction - Triple layer valve plate construction - Vulcanized black silicone gasketing for reliability and long product life - Individually pressure tested - One end of the valve is enlarged opening to accommodate the nominal duct diameter making the installation easier Learn More

The Damper Position End Switch provides a contact on AirValv Butterfly Dampers to allow service technicians to manufacture and wire their own form of visual or audible system to inform users of the damper position. Learn More

The NU-926/916 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).



Compatible Models: NU-407 425 / 437 / 440 / 602 / 629




Combine with NU-AIN-315BSC low flow exhaust monitor to comply with Standard NSF/ANSI 49.
