8-Inch Aura Attic Fan with Curb Mount Flange | AF-8-C4-CMF | 250 CFM

The 8-inch Aura Attic Fan with Curb Mount Flange is 8 inches in diameter and has a 4-inch tall collar. Its model number is AF-8-C4-CMF, which exhausts air out at 250 CFM. All 8-inch attic fans come with a standard 11.5 x 11.5-inch curb mount flange.

Benefits:

  • Energy-efficient attic fan ventilates at 250cfm 
  • Keeps your home comfortable and energy-efficient
  • Works passively with the wind when the motor is off
  • Inner louvers prevent insects and animals from entering the vent
  • Round aerodynamic design can withstand harsh weather

Installation: For low slope or flat roof ventilation

The Aura Attic Fan exhausts air continuously even when the motor is off. This attic fan works passively because of the Venturi Effect. When the wind blows against the outer louvers, this creates an upward draft, which allows air to flow freely out of the vent. 

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.

8-inch Aura Attic Fans are compatible with AVP's 6-inch tall, 8-inch tall, and 12-inch tall roof curbs.

8-inch Aura Attic Fans are compatible with AVP's insulated 6-inch tall, 8-inch tall, and 12-inch tall roof curbs. 

Motor Type: Shaded Pole C – Frame

With 1/55 horsepower and 250 CFM, this 8-inch vent is perfect for ventilating smaller attic spaces.

This Attic Fan also has an optional Shut-Off Switch, Thermostat, and Humidistat (THSOS).

How it works:

Energy-efficient attic fan ventilates at 250cfm 

The attic fan will still ventilate passively even when the motor is off. Even the slightest breeze can create exhaust ventilation to draw air out of the attic.

Calculate number of Model  AF-8-C4-CMF  Vents Needed for a Given Area

Enter the Width and Length of the attic space you need to ventilate to calculate the area. You may also enter the area directly in the "Area" field. It is not necessary to hit the Return or Enter key (which will refresh this page), just enter numbers in the fields.

Enter width of space to calculate area (or enter Area below)

The diameter size of all roof vents determines the Net Free Area, also known as the "NFA". NFA is the measured amount of opening each vent offers at each specific size. to be available for venting air through a specific vent size. The calculator below will find the overall number of vents needed to effectively ventilate the targeted attic space.

Once you have the area, the numbers shown below are the number of vents of that size which would ventilate the specified area with both 1/300 and 1/150 rule.

*Please note
The roof vent calculation values shown above are for the exhaust portion of the roof. The same amount of net free air inches is needed for air intake as well. Proper roof ventilation consists of 50% air exhaust and 50% air intake.
