Product Overview

More homes and businesses in the U.S. are protected by a GAF roof than by any other product. We are the leading roofing manufacturer in North America.

Nothing protects quite like a roof.

Nothing protects quite like a roof. That's why millions of Americans live, work, and play under quality products from North America's largest roofing manufacturer - GAF.

Always have a balanced ventilation system. The amount of exhaust ventilation should always be equal the amount of intake ventilation.

How much Ventilation do I need?

Include 1 sq. ft. of attic ventilation, evenly split between intake and exhaust, for every 300 sq. ft. of attic floor space.

Choosing the right attic ventilation for your home is very important. GAF offers a great selection of Master Flow and Cobra products.

What type of Ventilation do I need?

Review the ventilation options below to determine the best fit for your home application.

Available in both roof mount and gable mount, power attic vents exhaust the greatest volume of hot and/or humid air from the attic.

High efficiency Electric, Solar or Hybrid

Quickly removes large volumes of heat and moisture from your attic.

Cooler external air enters through vents lower on the eaves or soffits that “pushes” the hot/moist attic air out of the vents higher on the roof.

No electricity required

Allows excess heat and moisture to escape your attic without the need for electric hook-up.

Wind Turbines utilize the wind to pull heat and moisture from your attic and acts as a static exhaust vent when wind is still.

Wind-powered, smooth, and quiet operation

Utilizes the wind to pull heat and moisture from attic; acts as a static exhaust vent when wind is still.

Located at the lowest part of the roof, intake vents are a critical part of the attic ventilation system, allowing fresh air to flow into the attic

The most overlooked and critical part of attic ventilation

Allows cooler, fresh air to enter the attic at/near the soffits driving heat and moisture out higher exhaust vents.

Your home offers warning signs when your attic isn’t properly ventilated. You may recognize some of these signs in your own home.

5 Warning Signs

Here are some poor attic ventilation warning signs that you may recognize:

A possible cause of higher cooling costs could be insufficient attic ventilation, requiring the cooling system to run excessively.

1. Increased energy costs

Excess attic heat can cause your cooling system to work harder, raising your energy costs.

If you see that your shingles are dry or breaking, that could mean you have inadequate attic ventilation or you may need a new roof

2. Curling/cracking shingles

Inadequate ventilation can cause your roof shingles to curl and crack.

Moisture in the attic can become trapped and condense on rafters and insulation if not insulated properly. This can potentially increase energy costs

3. Roof decking moisture

Excess attic moisture can drip into attic insulation reducing effectiveness, even damaging ceilings below.

Stains or mold growth inside your home may be caused by inadequate attic ventilation. Excessive moisture in the attic allows mold and mildew to thrive

4. Attic mold/mildew

Excessive moisture can cause dangerous mold and mildew causing additional concerns.

Ice damming can cause water to enter the attic and house if you don’t have an adequate shingle underlayment or if the flashing has deteriorated.

5. Winter ice dams

Ice dams can cause expensive leaks and damage in attics, as well as living spaces.

Will this replace a Dow-135-0-34-Xin motor?

Asked by Gary August 2, 2020
1
Answer

Both motors have 1/2 inch shafts and similar RPMs, around 1100 RPM. The PMV-105 is 5.5 inches in diameter, and while the DOW-135-0-34-Xin is only 5 inches in diameter, the PMV-105 would probably fit in the existing fan collar, but tightly. The PVM-105 is also deeper, so fit could be an issue, depending on the fan application. The bigger problem is horsepower, as the DOW-135-0-34 is about 1/3 horsepower and the PMV-105 is only 1/9 horsepower, so using the PVM-105 as a replacement could cause the motor to fail rather quickly, depending on the fan being driven. I would look for a vent motor with more horsepower as a replacement for the DOW-135-0-34-XIn, such as the PMV-115, which is about 1/5 horsepower, although it is more expensive than the PMV-105.

Answers

I do not know if this will fit your application but have used it to replace roof vents on at least 4 different locations with obvious different manufacturers and had no difficulty. I suggest you check the dimensions of the existing motor housing and shaft and compare against this replacement. Also check the rpms on both.

I was prepared to pay someone $500 to replace my failed attic vent. On a lark, I decided to take a ladder to the attic to see if I could find the model number of the unit that the builder installed. Fortunately, the label was still present and a google search produced this item - it made my day! The video on the HD Website tells you all you need to know about how to go about replacing the motor. I did, however, find that the diameter and shape if this replacement is slightly different than the original but it still fits - just be sure to tighten all 3 clamp bolts on the vent frame. The toughest part of the job was tightening and loosening the fan blade, due the the fact that you need to reach in back of the motor, through the blades. 'definitely worth the effort, considering the money you will save!

Replacement motor for attic vent. The last one lasted 8yrs. Was fairly easy to replace (is done from inside, no need to remove vent cover or housing) and quieter than replaced motor. Hints: Make sure you have the correct size allen wrench available to remove the fan from the old motor shaft and replace on new. Slide fan up or down on new motor shaft before tightening, making sure fan blades do not scrape motor supports when tightened & turning. Hand turn fan, making sure blades are as equally level (easily bent to level out if necessary) as possible.

Although the replacement motor was a bit wider than the original, it fit perfectly. After loosening the allen screw on the fan blade loosening one screw on the motor bracket allows for the easy removal of the old motor and installation of the new motor. The entire job took me less than 45 minutes.

FAN-tastic
I purchased the PR2-HI22 in 4/8/2001 and installed a lighted inline switch in the closet to turn the unit off in the winter. The light install is attached to the dead side of the wire/switch, so when switched on there is a light indicator. I have not replaced the motor but purchased this replacement motor, just in case it is needed. I feel most who have had issues set the trip level too low which results in higher fan operation. Although, if you follow the instructions it recommends 105° F, I set the thermostat to 118° F. I also did my best to make sure the thermostat gets plenty of air flow when the motor is operating. Hope this information will assist those who have had issues.

Consider it a consumable
Razor blades are designed to wear out after a certain number of uses and so too are these motors. I recently purchased a new residence and the seller had two of these motors on hand to replace the two failed ones up in the attic. I placed a thermo probe in the attic prior to replacement - temp reached a high of 141 deg F. After replacement we are down to 102 deg F. As others have said, you need 2x 7/16 wrenches and an allen wrench (mine required 5/32 - odd). The bolt/nut removal for the housing is easiest when you have one socket drive and one closed end wrench. The fan is fairly loud when running but I can't hear it once my attic access door is closed.

I just bought this motor to replace an attic fan motor that started intermittently screeching last year (2019) and eventually froze up this year. Perfect fit, so far so good. When summer comes in 2021, that's when the true test starts. I just bought it hence the 4 stars so far. After time with it, the star rating may change. Installation was pretty simple, just be patient and maybe get an extra set of hands to help you hold it in place while you tighten everything down. Read the directions!

After two Broan motors seized up at about a year apiece, my research for something better led me here. The old fan blade fit right on and I only had to adjust location of the start capacitor for the O.E. mounting bracket to work. It runs quietly and draws fewer amps. I expect this to last longer, but time will tell!
