Air Vent Gable Mounted Power Fan

Description

The Air Vent Gable Mounted Power Fan is installed in the gable end of the house. It uses a thermostat to help prevent heat buildup and a humidistat (available in the 1620 CFM model only) to fight moisture buildup inside the attic. This Power Fan by Air Vent operates 30% more quietly than comparable units and with 35% greater efficiency. What's more, since many homes already feature a gable or gable vent, it may not be necessary to cut a hole to install the gable-mount ventilator.

The Air Vent Gable Mounted Power Fan is available in Humidistat/Thermostat 1620 CFM package that covers attics up to 2300 square feet, as well as Thermostat 1320 CFM package that covers attics up to 1900 square feet.

Features

• Patented rings instead of solid-steel housing, which pulls more air
• Automatic shutter available in white, but can be painted to coordinate with home's exterior
• One power attic ventilator is usually sufficient, unless it's a very large attic
• Roof-mount power vents are ideal for hip roofs
• Feature a preset adjustable thermostat for maximum homeowner convenience
• Gable-mounted power vents are an excellent option for tile roof ventilation

Specifications

• 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
