IDEA OF THE MONTH
LARGE HOOD AND EXHAUST SYSTEM FOR METALWORKING IMPROVE SHOP AIR QUALITY.
On their large Port Austin, Michigan, farm, one of the Murawskis performs maintenance almost every day in the shop. Often it’s at the 5×5foot metalworking workspace where either the wire welder or the cutting torch is in action.
The area stays smoke-free, though, due to their ample ventilation.
“This is nice, especially when there is grease on the steel we are torching,” says Ken Murawski. “It sure works better than the 6-inch pipe and squirrel cage fan we had in our old shop. The walls stay much cleaner, too.”
Though a system like this could easily be installed in an existing shop, this design was planned before they built new. The builders left an opening for the 24-inch fan, skipped putting insulation there, and added a small exterior hood angled downward to keep the rain out. Visitors often comment that they want to replicate the idea because of how smoky the air gets with inadequate ventilation.
