I have seen the one above in person, it is large. I have bought the parts to make a spray booth such as Rogers IE: explosion proof blower. Roger just opened the door a bit (as shown) & relied on the auction of the blower to pull the vapors out and away from the house, he had quite the long exhaust pipe to keep the paint of the house. I have needed one for ages Jim, & just haven't built one yet, I haven't decided on where I will put it.😋
