The 4 Seasons HP Flat Roof Solar Vent is designed and built for flat roof applications. The vent works by using the sun’s energy to power a fan which pulls excess heat, moisture and humidity out of the crawl space while promoting the air circulation inside.
This vent can operate from dawn until dusk, and still work as a ‘passive’ vent after sun-down. The sleek flashing is made of heavy spun aluminum and features a unique, weather resistant shape. Each vent comes with an interior insulation sleeve to prevent condensation buildup on the metal.
