The 16 inch Aura Attic Fan with Curb Mount Flange is 16 inches in diameter and has an 8 inch tall collar. The model number is AF-16-C8-CMF and exhausts air out at 1,800 CFM. All 16 inch gravity fans come with a standard 20 x 20 inch curb mount flange.
The Aura Gravity Fan exhausts air continuously even when the motor is off. This attic fan works passively because of the Venturi Effect. Wind blows against the outer louvers creating an upward draft that allows air to freely flow out of the vent. This Attic Fan is also available with an optional Shut-Off Switch, Thermostat and Humidistat (THSOS).
The curb mount flange allows for easy installation on roof curbs. In addition, the curbed flange can be used as a hatch to access the ductwork below. We recommend installation on roofs with a pitch of 2/12 or less.
16 inch Aura Gravity Fans are compatible with AVP's 6 inch tall, 12 inch tall, and 18 inch tall roof curbs.
With 1/4 horsepower and 1,800 CFM, this 16 inch vent is perfect for ventilating large attic spaces or plenums.
Even when the motor is off, the attic fan will still ventilate passively. In other words, even the smallest breeze can create exhaust ventilation to draw air out of the fan.
This movement of air is proportional to the wind speed and is measured in cubic feet per minute (CFM). Therefore, wind speeds of 11 mph for a 16 inch attic fan produces 497 CFM of air exhaust for attic ventilation.
