Description
The Dayton 5NRC3 is a heavy-duty, direct drive centrifugal blower designed for general ventilation, heating, and air conditioning sustems. It comes "less motor", meaning you must provide your own compatible electric motor. This design allows the blower wheel to mount directly onto the motor shaft, reducing friction and minimizing maintenance compared to belt-drive systems. The Dayton 5NRC3 is ideal for replacing worn-out exhaust or intake blowers in HVAC systems, commercial kitchen ventilation, or industrial air-moving applications. It is designed for clean, dry air and is not intended for chemical or hazardous environment applications.
Key Technical Specifications:
- Airflow Capacity: Ranging from a minimum of 245 CFM to a maximum of 1,250 CFM.
- Blower Wheel: 9-1/2 inch diameter steel wheel with a forward-curved, reinforced design for optimal air push.
- Shaft/Bore Diameter: 1/2 inch, which matches standard motor shafts.
- Motor Requirements: Accommodates direct-drive motors ranging from 3/16 HP to 1/2 HP.
- Speed Profile: Operates at standard speeds between 1,050 and 1,075 RPM (Note: this unit is not speed controllable).
- Static Pressure: Maximum static pressure rating of 1-1/8 in WC (Water Column), making it great for moving air through ducted systems.
Physical Dimensions & Build:
- Housing Material: Robust, galvanized heavy-gauge steel that is highly corrosion-resistant.
- Discharge Outlet: Rectangular shape measuring roughly 10-3/8 inches high by 9-1/8 inches wide.
- Versatile Mounting: Features a multi-position housing. The discharge orientation can be rotated into four separate 90-degree increments to fit your specific duct layout (e.g., top horizontal up-blast or bottom horizontal down-blast).
- Vibration Dampening: Includes a housing support equipped with resilient pads to lower operating noise and vibration.
- Adjustable Bracket: The included motor mounting bracket adjusts easily to secure blower motors measuring between 3-1/2 inches to 6-1/8 inches long.
