    Q:If I measured the vent and it measures 13 1hat size do I order 12 or 14
    by|Mar 26, 2021
    1 Answer
    Answer This Question

    A:  Master Flow only has a 12" or a 14" diameter turbine. If it measures 13" it may be a different brand. You might need to measure the base opening to get a correct measurement. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612, Mon- Fri, 8am 5pm EST.

        Ordered 2. One was slightly warped, second was extremely warped and rubbed against the frame while it spinned. Returned them and received the same 2 when I picked up the reorder. Cheaply made and obviously were damaged while handling somewhere along the way.

        This is the second Master Flow Internally braced turbine head I've ordered this year. The first one had no bracing, this one had external bracing. In both cases, the turbine stopped working after a short period of time.

          Hardest part was getting on the roof. Fit like a glove. Unfortunately I tore my good trousers on a nail, had to go to our sons wedding with a torn tuxedo.

          The thing has been off center and made noise since install. I left a request for info on how to fix it and this is the first follow up with a survey around a month later.
