Compressor Element
The quality of a compressor can be measured through the reliability, efficiency and durability of the compressor element used. Through decades of expertise in the design of compressor elements, the result is the production of most efficient and reliable compressors in the market. When the screw element is efficient durability excels, maintenance intervals decrease and fuel consumption goes down.
The CPS 185 KDU T4F compressor utilizes Chicago Pneumatic’s C111 which element is directly driven from the diesel engine with a fiber disc coupler. No gear box means less horse power required to produce the same volume of compressed air.
Inlet air is filtered through a heavy duty two stage air filter.
Air/Oil Separator
Air and oil separation is achieved through a centrifugal oil separator combined with a filter element. Separators are ASME/CRN approved versions and are stamped accordingly.
Designed for a higher maximum working pressure, the separator is equipped with a sealed high pressure safety relief valve, sonic nozzle, automatic blow-down valve, and pressure regulator.
Cooling System
The cooling system consists of integrated side-by-side aluminum oil cooler with axial fan to ensure optimum cooling. The fan is protected by a guard for operator safety. There is an access port at the front of the machine for easy cleaning.
The cooling system is suitably designed for continuous operation in ambient conditions up to 125°F, with canopy door closed.
Kubota
Kubota V2403 Tier 4 Final, naturally aspirated, four-cylinder, liquid-cooled diesel engine provides ample power to operate the compressor continuously at full-load.
Engine output at rated speed, in accordance to SAE Standard, is 49hp at 2700 rpm, as limited by the engine ECU.
The engine has the capability to start the compressor to 14°F (-10°C) with standard glow-plug aid. Cold start options are available for up to (TBA).
The 25 Gal (94L) fuel tank is sufficiently sized to operate the unit for minimum of 8 hours at full-load condition.
Instrumentation
The instrument control panel is located on the back, of the compressor canopy with easy access.
Standard instrument package includes an operating pressure gauge, and fully diagnostic ECU controller with large 3.5” display. The intuitive Chicago Pneumatic XC2003 controller is easy to operate with all functions conveniently at your fingertips. The controller also manages the engine ECU operating system, and a number of safety warnings and shut downs on various parameters
