    If we're talking more recent health and safety levels then its about 40 sheds of that size.

    If anyone vents vacs or DCs inside a shed then my recommendation is to force ventilate the shed.
    An oft referred to target is 20 room air changes per hour (RAC/h) but even 10 will be better than 5, which will be better than none.
    ouch…ok. When i checked the filter in the vac the other day it looked clean, but i didnt take it off. I’ll have a better check today. Appreciate the insight Bob.

    cheers

    Bookleaf's solution is probably the best compromise.
    absolutely…i have a very small workshop and a small footprint was a big priority..side by side was not an option for me. There are many ideas around for these things, some maybe better (efficient) than others.

    Neat

    (Not having a go at anyone here)

    99.9% of information on the internet is wrong and should be ignored.
    That's probably a good way to live in general lol

    Chris's comment was in relation to room air filters, NOT cyclone equipped vacuum cleaners. Take your point about peoples perceptions though.

    are you hooking that setup to the 4" pipe in the background?
