Greenheck SP-A390-QD Ceiling Exhaust Fan
The Greenheck SP-A390-QD is a professional-grade ceiling exhaust fan engineered for high-performance air evacuation in commercial and multi-family residential environments. This direct-drive unit delivers a versatile airflow range of 279 to 410 CFM, making it a reliable solution for maintaining air quality in large restrooms and clean air applications. Constructed with a galvanized steel housing and lined with acoustic insulation, the SP-A390-QD is specifically designed to minimize decibel output, achieving a sound rating as low as 4.5 sones at 0.125 in. wg. As a veteran technician's choice, this model features a PSC motor with internal thermal protection and is speed controllable for precise system balancing. The inclusion of a spring-loaded aluminum backdraft damper prevents air migration and eliminates the rattling often found in lower-tier residential units. With its AMCA Air & Sound certification and UL/cUL 507 listing, the SP-A390-QD ensures rigorous compliance with mechanical codes. This centrifugal ceiling fan integrates a polypropylene wheel for durability and provides external electrical access to streamline site installation.
Key Benefits
- Quiet Operation: The insulated galvanized steel housing and precision-balanced centrifugal wheel significantly reduce vibration and ambient noise.
- Optimized Efficiency: Features a high-efficiency PSC motor (115V/1Ph) designed for continuous duty and lower power consumption.
- Reliable Backdraft Protection: The spring-loaded aluminum damper ensures a tight seal to prevent unconditioned air from entering the space.
- Ease of Installation: Designed with external electrical access and adjustable mounting brackets to reduce labor time for contractors.
- Code Compliance: AMCA certified for air and sound performance, ensuring the fan meets specified submittal requirements.
Common Questions
What is the duct size for the SP-A390-QD?
This model is equipped with an 8-inch by 8-inch square discharge outlet, typically requiring a transition for standard round ducting in the field.
Can this fan be used in fire-rated ceilings?
To maintain the fire-resistance rating of a ceiling membrane, this unit must be installed with a compatible ceiling radiation damper, such as the Greenheck CRD-320.
Is the motor speed adjustable for balancing?
Yes, the PSC motor is speed controllable using a solid-state motor speed controller to fine-tune the CFM delivery based on specific field conditions.
