These systems are all custom.  Fax us your shop layout-draw in the bays and the building walls, and we’ll provide an exhaust system layout, complete with duct sizing, and a bill of materials.

OSHA requires vehicle exhaust mitigation.  The system can be as simple as crush proof hose fed out through a door port, or as complicated as a multiple blower system used in conjunction with a duct rail system.  So if you run vehicles indoors, plan on installing some type of system.

While inground systems offer a clean, uncluttered look, the downside to these systems is that underground duct is susceptible to collapse (always use schedule 80 PVC-never use duct) and water and debris issues.  Additionally, underground systems require the use of highly skilled installers-the floor ports need to be installed so that after the floor is poured, they are level and flush to the floor. Above ground systems are much easier  and cheaper to install, and you can visually inspect them at all times.

Cars and light trucks require 300-400 cfm of blower capacity per port.  Diesel engines (over the road trucks, e.g.) require up to 600 cfm per port.  Make sure you size your blower properly (or call us and we’ll do it for you).  If you don’t the exhaust won’t move out of the building and you’ll burn up your hoses.

If you are using a dynamometer, or if you’re testing hydraulic components, you need a lot more air flow.  Call us.
