[TheForge] positive pressure room

[Jay Hayes]

Mikey,
That is correct. The heavier the particulate is the higher the velocity 
the air needs to be to move it. The paint booth I turned into a grinding 
room is a large twelve foot wide walk in type booth with a 36 inch 
explosion proof fan. We reconfigured the filter bank with baffles to 
increase the down draft velocity. It's sweet and helps keep most of the 
grit and dirt out of the main part of the shop. Our old sanding / 
grinding room was a Binks 22 x 30 booth with a 16 foot down draft bench 
on one wall and two six foot down draft benches on another wall. It was 
great for small stuff but was only fair for large items like railings or 
spiral stairs. The new setup is more versatile and better utilizes space.
