can this be used to vent bath exhaust fan

Asked by David November 19, 2020
5
Answers

Yes. We brought this unit two years ago and installed it to vent our bathroom fan. It works great. We are very happy. Set ours up with a timer we can set from 10 minutes to 60 minutes.

Yes pretty heavy metal and well made. The damper needed a little adjustment but other than that it was worth the price. Much better than some I have seen.

Answers

You could use a 6" hole saw, if the fit is too tight, use the hole saw to wallow it out a little. Another method is to use a jig saw. This will give you the best fit.

Will this accommodate a 6" fan with a 6" exhaust duct that pushes 350 cfm?

Asked by Jonathon January 2, 2020

Answers

This will work to exhaust 6" ducts,The GNV6BL does not have a CFM rating. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.

Is supply duct from bathroom 4 inches?

Asked by Kenneth October 19, 2019
5
Answers

Yes, some supply lines are 4 inches but some are 6 inches. I have two that are 4 inches and one that is 6 inches. You can use a 4x6 duct reducer to complete the connection.

Can this vent cap be used on a range hood with 150 to 500 CFM?

Asked by Synthia October 10, 2019
3
Answers

See MasterFlow answer below. This should work fine. Assuming your range hood has a 6" outlet, the manual should specify maximum length of 6" exhaust rigid duct. 90 degree elbows count as 5ft of duct. Usually duct termination caps are considered zero ft of duct in the calculation. I put 3 of these roof caps on my new home. One on a 500-cfm hood, another on a 450-cfm hood, and the third one exhausts a variable speed 300-1000 cfm mult-port bath fan,

Can I use this vent roof cap for a range hood with a CFM of 250 to 500?

Yes:: properly secured the vent will work just fine.... Would probably recommend then ridged pipe also

can this vent handle 860 cfm blower

Can I use a fan of 80 CFM blower?

can this be installed on a flat roof?

Asked by carlos April 6, 2019

Answers

Mine is installed on a 12/12 pitched roof. I don't think it would be a good idea on a flat roof due to it's construction and it's seams. I would guess it could be very prone to leak with any standing water.

This product is not heavy, easy to install. I like how it looks and great service to pull all the odors from the of kitchen. Thanks

Great product
Wished perfectly with 6" flex duct on our microwave range hood. Verified that the damper goes upand down. The only primeval i have is the flange is only 2" each side, so must tar the heck out of around and under it. Otherwise love them. I've installed dozens on customer homes. Look nice, never a major problem.

This product is so easy to install. I used this for my exhaust vent and so far water tight. Recommend a tube of roofing tar when you purchase this product.

Works, and fits great for a range hood roof vent. Quality of the sealants on the vent is on the low side, with holes and gaps missed. But not a big deal to just reseal it when installed.

Not Hurricane-ready
The airflow on this thing was OK, while it was working. But two weeks after installing this, Hurricane Zeta hit that side of my roof, full aspect (we had southerly gusts over 90mph here). It's installed on a 6-in-12 roof pitch, facing south. We heard a loud bang from our range hood during the height of the storm, and the next day the range hood was louder and far less effective. I went up on the roof the next day to see what was going on, and what I found was that the damper flap had somehow made its way UNDER the metal edge that it is supposed to seal down against, along the front. It was nearly a 100 mph wind that went straight into the front of this thing, and they obviously never designed it to handle that sort of thing - but they SHOULD have. Anyway, the damper flap was jammed closed. I was able to take the grill off and flex the damper flap back over the front edge of the housing, and get the vent back to working again. But I think I'm going to need to make some kind of a hurricane shutter for this thing. It seems to me that a company who manufactures roofing materials with 150mph+ wind ratings should do a better job designing a roof vent. Some wind tunnel work would have gone a long way, GAF... This roof vent is very flimsy.
