Base mount means you're getting the air end, motor, belt drive, controls, and mounting frame. If your facility runs 460V 3-phase power and you have an existing receiver tank or need to replace a compressor head on an existing system, this is how you get rotary screw output without paying for a tank you already have.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote: The R43BMP60-460 was not listed individually on Castair's website at time of writing. Specifications below are based on Castair's confirmed rotary screw product line and model number conventions.
