Greenheck SP-A390-VG-QD Exhaust Fan
The Greenheck SP-A390-VG-QD is a high-performance ceiling exhaust fan engineered to provide superior air movement with ultra-low sound levels, making it a staple for multifamily housing, hotels, and premium residential bathrooms. This direct drive centrifugal fan features a Vari-Green EC motor, allowing for exceptional controllability and efficiency across a wide range of operating points. Designed with a tri-voltage capability (115/208-230/277V), it simplifies inventory and job-site electrical requirements for technicians. The unit is AMCA licensed for sound and air performance, delivering up to 410 CFM while maintaining an ENERGY STAR rating. Its galvanized steel housing is fully lined with 1/2-inch acoustic insulation to dampen vibration and mechanical noise, while the spring-loaded aluminum backdraft damper prevents rattling and cold air infiltration. For a clean finish, the included tapered duct adapter ensures a secure connection to 8x8 inch ductwork, while the designer grille provides a professional aesthetic without restricting airflow.
Key Benefits
- Integrated Vari-Green motor technology provides maximum fan controllability and significant energy savings compared to standard PSC motors.
- High-static pressure performance up to 1.0 in. wg ensures reliable clean air exhaust even in complex duct runs.
- Reduced field labor through external electrical access and a universal tri-voltage motor that eliminates wiring guesswork.
- Superior vibration isolation and sound absorption via insulated housing ensure nearly silent operation in sensitive environments.
- UL/cUL 507 listed for use over bathtubs and showers when installed with GFCI protected branch circuits.
Common Questions
What duct size is required for the SP-A390-VG-QD?
This model is designed with an 8-inch by 8-inch square discharge, requiring a compatible duct connector assembly for standard HVAC transition to round or rectangular ductwork.
Can the airflow be adjusted after installation?
Yes, the Vari-Green electronic motor is fully speed-controllable, allowing contractors to dial in the specific CFM needed to meet code requirements or balance the ventilation system.
Is this fan suitable for continuous operation?
The totally enclosed non-vented motor and high-quality centrifugal wheel are built for durability in continuous-duty applications where moisture and consistent air movement are factors.
