    I am putting together a small home workshop. There will be some work that requires extra ventilation even it just paint fumes. I have a working kitchen extractor hood and was planning on using that as some help. Get that it is not going to be as good as an industrial extractor fan but it is a small garage and only occasional use.


    Is this reasonable or it there a way to calculate the air capacity and calculate out much use it would be?

    You be much better off using an inline extractor like the below. They shift so much more air than a kitchen hood

    In order to capture fumes you need the extractor to generate an air velocity of at least 0.5m/s at the location the fumes are generated . This is probably difficult to achieve with a domestic fan unless it's on top of the object your painting .


    There are some calcs here you may be able to use if you have an idea of the flowrates etc. https://www.engineeringtoolbox.com/exhaust-outlet-d_1008.html

    I'll give you a bit of a laugh... I was trying to size a fan for an open kitchen and called a fan manufacturer in Dublin for advice. It was to be a wall mounted fan, some distance from the cooking island so there were challenges around capturing the vapour/smoke etc.

    He quickly asked for the dimensions of the rooms alongside the open kitchen (dining and sitting) and advised that due to the fact that it was open-plan, these would need to be factored into the calculation. A few quick taps later he told me that I'd need a fan with a diameter of 1 and a half foot with an open area of about 250 square inches... needless to say I didn't fancy replacing the cupboards with a gaping hole reminiscent of every prison-escape movie with spiders and insects draped out of it. I stuck with my carbon filter island fan instead.
