Thank you for inquiring about MasterFlow Products ... Yes, this item would be recommended for this application.t make the soffit vent has the cfm capability to exhaust all air if both fans are operating a the same time. Please call our Technical Services Group at 800-211-9612 , M-F 8A-5P ET, with any additional questions.

Rated 4.9 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by The Only Way To Solve a Reduced Flow Prblem We were building a very large wood dust collection system which needed to have very free flow - much better than Tees could provide. Unfortunately, I can't provide pictures of just how successful a solution the Wyes provded as the system passes throgh walls and some portions are very high. BUT, early tests of the system indicated 30 - 40% over using Tees and flex duct. Had I known of their of their availability (at store level), i would have designed the system from "scratch" to incorporate this excellent product. The whole prcess from the store to my door was another example of extremely smooth flow. December 8, 2015
Rated 5.0 out of 5.0 by Right product for the job This connector makes the connection of two ducts work great. December 15, 2015
Rated 5.0 out of 5.0 by Good Wye Easy to install, prefer metal wye to plastic to mitigate static and chance of fire. November 10, 2015
Rated 5.0 out of 5.0 by sufficient purchase for the job Master Flow 4 in. x 4 in. x 4 in. Wyes used for reducing laterals to 2 pipes. Got the job done in no time. Easy to find at home depot after after review it on line. SKU# and availability made the trip to HD productive. October 27, 2015
Rated 5.0 out of 5.0 by Fantastic This high-quality aluminum piece is ideal for easy airflow by avoiding a 90-degree angle while tying in two air ducts. This specialty piece seemed impossible to find anywhere - so glad Home Depot had it online! February 12, 2015
Rated 4.0 out of 5.0 by Not available in Stores I ordered this 4" duct wye because it was not available in stores. It is all that it is supposed to be. Note: this particular type is not for venting furnace or gas water heaters. February 19, 2015
Rated 5.0 out of 5.0 by Worked out great These fittings are being used in my dust collection system in my woodshop. They were delivered without damage and in good time. The seams are easily sealed with a premium silicone duct caulking to prevent leaks that is the downfall of any dust collection system. December 11, 2012
Rated 5.0 out of 5.0 by This Product Works like a dream Was glad I checked at Home Depot. They had what I was looking for and if it was not in stock they would order it for me. I love shopping at Home Depot November 15, 2011
