Ventilation Requirements
Adequate ventilation is vital for safety as well as proper
operation of the engine. Systems without adequate cooling
may experience stalling, premature oil deterioration,
increased oil consumption, power loss, and reduced life or
failure of the engine and/or compressor.
If the compressor overheats, the temperature switch will
shut down and disable the engine until the oil temperature
drops below 140 °C (284 °F).
During operation, the Gas Engine Driven 30 CFM Air Compressor generates
a considerable amount of heat that must be evacuated away from the unit for
it to run efficiently. The engine is air cooled and requires an adequate supply
of cool fresh air to cool the engine and allow proper fuel combustion.
Ensure there is a minimum of 6 in of clearance between the engine air intake
(the recoil starter area) and any other components mounted on the vehicle.
The WHASP cooler fan should have a minimum of 12 in of clearance in front
of it, however unobstructed venting to open atmosphere is preferred.
The engine exhaust must be vented away from the Gas Engine Driven 30
CFM Air Compressor and toward a safe location (the exhaust tip can be
rotated to change the exhaust direction if needed). If mounted in an enclosure
(such as the bed of a pickup truck box), the exhaust must be vented outside
of the vehicle to prevent the gas engine from ingesting its exhaust and
overheating or stalling (Figure 8).

Exhaust and waste heat from the Gas Engine Driven 30 CFM Air
Compressor system must be vented away from the system to
prevent the gas engine from ingesting its exhaust and stalling.
