Right-Sized Ventilation
Not every attic requires the largest ventilation system available. For smaller attics with good southern sun exposure, a compact solar attic fan can help manage excessive heat without taking up unnecessary roof space.

Product Overview
WHY THIS MODEL
Compact Size Without Sacrificing Performance
Solar-Powered Performance
The fixed 25-watt solar panel powers a variable-speed 24-volt brushless motor. Because the fan operates using solar energy, it requires no connection to the home’s electrical system and does not add to the homeowner’s electric bill.
Best for Strong Sun Exposure
The fixed-panel design is best suited for a roof surface with strong southern sun exposure and an attic with adequate intake ventilation.

INSTALLATION MATTERS
Replacement Air Is Essential
An exhaust fan must have access to replacement air. Before installation, contractors should confirm the attic intake pathways are present, properly sized and free of obstructions.
- Inspect soffit vents
- Confirm baffles are open
- Verify a clear intake-to-exhaust airflow path
