Thea Air Vent Roof Mount Attic Vent with Humidistat/Thermostat consist of electric-powered attic vents use a thermostat to fight heat and a humidistat ("Plus" models only) to help prevent moisture buildup inside the attic. Featuring a low-profile dome, the power roof vent is unobtrusive when installed on the roof face slanting away from the front of your home. It's an efficient option to replace wind turbines or roof pots already in place.

Due to limitations of certain monitors, the colors you see on your screen may not be a totally accurate representation of the actual product. We strive to make our colors as accurate as possible, but screen images are intended as a guide only.

Automatic thermostat and humidistat fights heat buildup along with thermal overload protection (an important safety feature that shuts off motor if fan overheats)

Six brace struts firmly hold dome in place

Raised dome for greater airflow and easier flashing

Plastic screen has distinct advantages over metal: it won't corrode or rust, and it won't vibrate or create noise

One power attic ventilator is usually sufficient, unless it's a very large attic

Roof-mount power vents are ideal for hip roofs

Features a preset adjustable thermostat for maximum homeowner convenience

Gable-mounted power vents are an excellent option for tile roof ventilation

1170 CFM for attics up to 1650 square feet

Oversized 24 inches x 24 inches G-90 galvanized base for easy nailing and flashing

Pre-painted 22-gauge galvanized steel dome is more durable than aluminum with painted screws to match dome color

Most power attic ventilators only have a thermostat, so they only monitor the heat in the attic. Moisture buildup is also a problem in the attic. A solution is a power attic ventilator featuring a combination thermostat/humidistat. (See "Plus" models.)

For proper attic ventilation, the Home Ventilation Institute recommends a system that provides at least 10 air exchanges an hour. To determine the fan capacity needed to provide this minimum airflow, use the following formula: attic square feet x 0.7 = CFM (cubic feet of air moved per minute)

Power vents are rated by CFM. Look for a power vent that provides at least the minimum CFM requirement. Remember, the higher the CFM the more air exchanges per hour.

Note: for roofs 7/12 or higher, you may want to add 20% more CFM capacity to handle the larger volume of attic space; 30% more for roofs 11/12 and higher

Adequate soffit venting must be installed for best performance (If using gable vents, gable vents must be installed on the down-wind end of the home)
