DescriptionThis four-stage piston-type compressor assembly is driven by an induction-type electric motor through a belt drive. A control panel, part of the HPBAC system, provides a MANUAL/AUTO selector switch that allows the operator to select the mode of operation. The compressor draws air through tan inlet filter. Before leaving the HPBAC system, this compressed air is passed through a purification system to achieve ANSI/CGA G-7.1 Grade D breathing quality. The compressor, motor, and control panel are vibration-isolated from the main frame. The base of the main frame incorporates cable-mount type isolators that can be mounted firmly to the installation structure. The system is shipboard-qualified and meets shock and vibration requirements.
