Excavator exhaust fume control

[Muz]

I have a client wanting to use a digger inside a fairly clean factory (not food) and exhaust emissions will be a problem. A venting system is not entirely suitable so I was looking at this company http://www.rentavent.co.uk/contact but the numbers are dead ? .. anyone have any ideas for such a system ? or has anyone come across this company ?

When I was in the firebrigade we used to do tactical ventilation! We would put a large fan outside at a doorway and then fire in fresh air but you need an exit 2/3s the size of the entrance iirc so it has a good flow. Maybe that's something to try? When seething the outside fan up you make sue it's covering the whole door way making a good feed in! You don't have to use one fan you can do 2 side by side or even inline to give a big force!
