CURB MOUNT
SOLAR POWERED
ATTIC VENTILATOR
TYPICAL SPECIFICATION
Curb Mount Solar Powered Attic Ventilator shall be Broan Model
345CSOBK (345CSOWW).
Ventilator to be rated for attics up to 3,200 cubic feet.
Ventilator shall mount easily between rafters or wall studs.
Solar panel to be rated at 28 watts and have high transmission,
tempered glass.
Motor shall be direct current (DC), variable voltage, sealed,
permanently lubricated, and corrosion resistant.
Fan blade to be metal, balanced, and corrosion resistant.
Dome and base must be constructed of ultraviolet resistant plastic.
Brackets, hardware and screen shall be corrosion resistant.
Perimeter of solar panel and wire opening sealed to prevent water
intrusion.
Powerful and easy to install, these ventilators
supplement air conditioning by automatically
removing the blanket of hot, trapped air from
attics without the need of AC power.
