• the compressor can also be supplied with sound deadening insulation to lower noise emissions to meet specified requirements.
• the compressor cooling system 15 can involve components such as a radiator, high capacity fan, and thermostats.
• the high capacity fan draws air through the radiator, keeping the engine motor 19 at the desired operating temperature.
• the same fan also cools the fluid in the compressor cooling system 15. While passing through the radiator, the fan air also passes through the compressor fluid cooler. As air passes through the cooler, the heat of compression is removed from the fluid.
• the same fan also cools the engine intake air supply. While passing through the radiator, the fan air passes through an air to air aftercooler. As air passes through the air to air aftercooler, heat is removed from the engine motor 19.
• fluid is injected into the compressor unit and mixes directly with the air as the rotors turn, compressing the air.
• the fluid flow has several functions. As coolant, the fluid flow controls the rise of air temperature normally associated with the heat of compression. The fluid flow further seals the clearance paths between the rotors and the stator and also between the rotors themselves. The fluid flow also acts as a lubricating film between the rotors allowing one rotor to directly drive the other.

• the air flows through an aftercooler and water separator (if equipped) then to a service line while the fluid is being cooled in preparation for reinjection.
• the air compressor discharges compressed air/fluid mixture into the receiver tank 16.
• the receiver tank 16 has several functions including acting as a primary fluid separator, serving as the compressor fluid storage sump and housing the final fluid separator.
• the compressed air/fluid mixture enters the receiver tank 16 and is directed against the tank side wall. By change of direction and reduction of velocity, large droplets of fluid separate and fall to the bottom of the receiver tank.
• the fractional percentage of fluid remaining in the compressed air collects on the surface of the final separator element as the compressed air flows through the separator. As more and more fluid collects on the element’s surface, the fluid descends to the bottom of the separator.
• a return line (or scavenge tube) leads from the bottom of the separator element to the inlet region of the air compressor. Fluid collecting on the bottom of the separator element is returned to the compressor by the pressure difference between the area surrounding the separator element and the compressor inlet.

• fluid is used in the system as a coolant and a lubricant.
• the fluid is housed in the receiver tank 16.
• the fluid taking the path of least resistance, flows to the thermal valve 22.
• the fluid first enters the thermal valve 22 and then flows to the compressor unit, bypassing the cooler 24.
• the temperature of the fluid rises and the thermal valve element begins to shift. This forces a portion of the fluid to the fluid cooler.
• the cooler is a radiator-type that works in conjunction with the engine fan. The fan draws air through the cooler removing the heat of compression from the fluid. From the cooler, the fluid is routed back to the thermal valve.
• cooled fluid is mixed with warmer fluid.
• a certain desired implementation e.g., such as 230°F (110°C)
• the thermal element shifts completely causing all fluid to flow to the cooler 24.
• the thermal valve 22 incorporates a pressure relief valve, which allows fluid to bypass the cooler 24, if the cooler becomes plugged or frozen. This helps assure that fluid will continue to be provided to the compressor for lubrication.
• the fluid passes through the thermal valve 22 it is then directed through the main fluid filter 21. There, the fluid is filtered in preparation for injection into the compression chamber and bearings of the air compressor.
• the filter 21 has a replaceable element and a built-in bypass valve which allows the fluid to flow even when the filter element becomes plugged and requires changing or when the viscosity of the fluid is too high for adequate flow. After the fluid is properly filtered, it then flows on to the compressor unit where it lubricates, seals and cools the compression chamber as well as lubricates the bearings and gears.
• the fluid stop valve 23 functions on shutdown when it shuts off the fluid supply to the compressor unit.
• the fluid stop valve 23 is held open by a pressure signal from the compressor discharge. At shutdown, the pressure signal is lost and the fluid stop valve 23 closes, isolating the compressor unit from the cooling system.
