Features a control that allows engagement or disengagement of the compressor clutch circuit. The cutaway swash plate compressor is designed to allow students to see the internal operation of a variable displacement AC compressor. Swash plate can be manually moved to demonstrate different output modes.
Main Features:
Features a control that allows engagement or disengagement of the compressor clutch circuit
Allows visualization of internal operation of a swash plate/piston type variable displacement A/C compressor
Requires a separate power supply or 12VDC battery to operate
Driven by hand crank.
The Cutaway Variable Displacement swash plate type design is equipped with an operational 12VDC electromagnetic clutch that can be applied or disengaged with a switch. Also includes a feature that allows the demonstration of improper performance caused from a slipping compressor.
