The two most common types of room exhaust systems are Hood and Pipe systems. Hood Systems are preferred because connection to the engine is not required. The hood fan pulls make-up air into the room and removes both engine and room exhaust. Pipe Systems can be powered by a fan to remove engine exhaust. When using a pipe system, a separate fan-powered room air exhaust system is necessary to pull make-up air into the room and to discharge heat, smoke and fumes.

• Remove engine exhaust
• Ventilate room to remove heat, fumes, and smoke
• Provide air supply for engine combustion
