24-Inch Aura Attic Fan with Curb Mount Flange | AF-24-C8-CMF | 4,800 CFM

The 24-inch Aura Attic Fan with Curb Mount Flange is 24 inches in diameter and has an 8-inch tall collar. The model number is AF-24-C8-CMF, which exhausts air at 4,800 CFM. All 24-inch attic fans come with a standard 28 x 28-inch curb mount flange.

Benefits:

  • Energy-efficient attic fan ventilates at 4,800 cfm
  • Keeps your building comfortable and energy-efficient
  • Works passively 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. The wind blows against the outer louvers, creating an upward draft, allowing air to flow freely from the attic. 

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.

24-inch Aura Attic Fans are compatible with AVP's 6-inch, 12-inch, and 18-inch roof curbs.

Motor Type:  PSC – Open Ventilation

With 3/4 horsepower and 4,800 CFM, this 24-inch vent is perfect for ventilating large attic spaces or plenums.

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

How it works:

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-24-C8-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)
Enter width of space to calculate area (or enter Area below)

If you know it, you may enter the area directly here

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.
