Questions & Answers
can this be used to vent bath exhaust fan
Asked by David November 19, 2020Yes. 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.
Can this be used as an intake for a fresh air system?
Asked by Robert October 18, 2020No,the device has a flap on it to allow air to flow out.
Is it really galvanized?
Asked by John August 10, 2020Yes 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.
Should I buy a 6" hole saw for cutting my roof hole to fit the inlet duct through, or will that b...
Asked by quickquestion March 31, 2020You 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, 2020This 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, 2019Yes, 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, 2019See 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?
Asked by Synthia October 10, 2019Yes:: properly secured the vent will work just fine.... Would probably recommend then ridged pipe also
can this vent handle 860 cfm blower
Asked by carlos April 6, 2019Can I use a fan of 80 CFM blower?
can this be installed on a flat roof?
Asked by carlos April 6, 2019Mine 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.
