Product Overview

Active Ventilation Products Aura Ventilator Retrofit product line is designed to fit over a turbine ventilator roof base. It has a flared adapter that easily fits over an existing roof mounted metal base. The Aura Ventilator Retrofit has a patented engineered design to create CFM (Cubic Feet per Minute) of air flow with no moving parts. Model AV-12-RF has a 12 in. Dia throat opening and will produce 310 CFM at 11 mph with no moving parts. It is an excellent choice to exhaust attic heat in the summer and moisture in the winter. The Aura Ventilator Retrofit product line is made of durable rust free aluminum and has 2 manufactured components: The vent head and adapter. The vent head’s patented design has three concentric cylinders with slotted vertical louvers. When air moves against the louvers of the outer and middle cylinders it is directed to create a circular airflow while spinning against the inner louver section. This air movement creates a Venturi effect which produces a vacuum or negative pressure to pull air from within the attic space. The vent has a flat one piece spun cap that prevents rain and snow from entering the vent verses the turbine vent which is open to the sky and allows rain water to enter in “no wind” conditions.

  • Easy to install
  • Noiseless, does not require electricity to exhaust air from attics spaces
  • Leveling is not required, the aura ventilator retrofit can be installed parallel to the roof
  • Built-in inner vertical louvers has an 1/8 in. opening between the louvers to keep out insects, birds and squirrels from entering the vent while allowing optimal air flow and no maintenance
  • Will reduce attic temperatures in the summer and will keep the attic dry and cool in the winter to preserve attic insulation and prevent ice dams
  • Round aerodynamic design can with stand harsh weather and wind forces of up to 200 mph
  • Mill finish aluminum color that will continually have a long lasting clean appearance
  • Net free air space: 113 sq. in.
  • Ventilation rule 1:300 (1 per sq. ft. of attic space): 1 vent per 450 sq. ft. of attic space
  • Helps to reduce energy costs
  • 5-year warranty

Answer: 
It will work on a sloped roof. It might perform better in the vertical position, but most bases can be adjusted if the collar is long enough.

Answer: 
This product replaces the turbine, or ventilator, part of an existing installation. It is for retrofit only and does not include the flashing or mounts that attach to the roof.

Answer: 
Usually the bases will rotate so they are vertical even on a slanted roof. To get the best air currents, so the vortex can accomplish it's job, I think vertical would be the best position. However, I think they would work on a standard slanted roof, no more than a 4-12 pitch. Anymore than that, they may leak during a rainstorm, especially in thunderstorm where rain is blowing in all directions.

This would be the 1st turbine on my house. Do I need to buy any additional items? Would you recommend Powder coating over the aluminum in AZ?

Rated 4.5 out of 5 by 31 reviewers.
Rated 5.0 out of 5.0 by How do you achieve inner peace. Buy this item! Thats how I had such a noisy wind turbine. Drove me up the wall. Here in sunny South Florida we get a lot of wind. I did not want to attempt installing a whole new unit so i put it on the back burner for a while. Just the other day I decided I could not take the noise anymore and I looked for some retrofit wind turbines. This popped up ( genius ) No moving parts means no parts to break. Took about 3-4 day to deliver to my local Home Depot store. Arrived well packed in a sturdy corrugated box. Came with 4 self tapping screws. Took about 10-20 minutes to install. As Im writing this on a super windy day. I have achieved inner peace. My home office is very silent. No clinky clanky clunky noise. You can contact us through our website www.pmcases.com if you would like a followup to see how its holding up. February 19, 2016
Rated 4.0 out of 5.0 by Reasonable price, easy(ish) install I purchased two of these vents to replace one broken and one bent wind turbine type vent. The retrofit vent is a very snug fit over the old pipe, and I found it necessary to use pliers and bend the pipe in a bit to get it to slip on. Because of this, I was unsure if the four self drilling screws provided actually penetrated both pieces of metal. So I bought additional self piercing screws and put three extra screws in to be sure that the vent was completely secure. I cannot say if the new vents outperform the old ones but they appear to vent at least as well, because I have not noticed a rise in heat in my home. July 12, 2016
Rated 5.0 out of 5.0 by Very good upgrade to the old fashioned wind turbine vents! I had a leak in my roof and spend a few storms checking the roof thinking it was around a pipe or the dish satellite dish. After sealing up everything I could think of, I determined that it had to be the wind turbine vents on my roof. When it rained hard, the rain would just pout in as they were open to the sky. The new replacement vents are not open to the sky and were an easy to retrofit. They are very good looking and well made. Last hard rain shows that they fixed the problem I was having with the wind turbine vvents. Also noticed that the venturi effect of these vents really work. Tested the temp of the attic and even used a little smoke to show the effect as the hot air left the attic via the vents. December 8, 2015
Rated 4.0 out of 5.0 by Sure beats the whirlybird with brgs going bad For the negative customers that returned them for the whirlybirds that claim to have perminate lubed roller bearings, they can and do puke out the bearings and fail. Then they squeel and squeak and make a horrible noise heard all over the neighborhood. Also to the ones that say they don't move air at all, neither do the whirly birds when their isn't a breeze. I tried the whirlybird and they aren't the same as the ones that lasted a lifetime, not to mention the rain getting thru the vanes when they aren't spinning June 2, 2016
Rated 5.0 out of 5.0 by Just what we needed These are exactly what we needed. A family member re-roofed our house and didn't get the turbines back on correctly. There was no way to level without tearing up the new shingles. These worked fine as a replacement if not perfectly level. Installation was easy, we just unscrewed the old turbines, slipped on the new vent to mark the holes and drilled to use the old holes. Including painting, we put on 3 in an hour. They've only been on the 1st two weeks of April, so I can't attest to performance in high summer. So far, so good though. One point, HD jacked up the price of the black ones by $20 each after we looked at them once online. So we ordered the silver ones and spraypainted them with a $4 can of black BBQ grill paint.

Rated 5.0 out of 5.0 by Retrofit wind turbine I installed 4 of these to replace old warn and noisy turbines. They arrived in good time and good shape, fit well and went on easily with the 4 included self tapping screws. December 8, 2015
Rated 5.0 out of 5.0 by Great replacement for turbine vents!! Simple removal and replacement of decades old turbines. Much lower profile, so less visible, and much better at preventing rain from entering the attic. Also much better appearance. Slightly damaged in shipping, but easily bent back into shape. April 12, 2016
Rated 4.0 out of 5.0 by Very nice! Product was ordered online and picked up at local store. It arrived days ahead of the promised date. Although I have not yet installed the unit, it is good looking, light weight, well constructed and appears to be carefully engineered. It even comes with 4-self tapping screws for installation in a zip lock bag taped to the inside of the ventilator. April 26, 2016
