The C3 duplex pairs two 15 HP cast iron two-stage pumps on a shared tank — one active, one on standby with automatic alternation and failover. At roughly 100 CFM combined capability, the C3 duplex handles the highest sustained air demands while providing genuine redundancy. This bundle covers dual aftercooling, automatic drains, hour metering, dual control, intake silencing, and vibration isolation — all factory-installed and matched for a 460V duplex C3 installation. Bundle saves 10% over individual option pricing.\u003c\/p\u003e\u003cp\u003eThe C3 duplex is not a common purchase — it's the compressor for facilities that run large spray booths, sandblasting operations, or production manufacturing where air is a utility that cannot go down. If you're evaluating a C3 duplex, you already know why you need it. This bundle ensures the support systems match the scale of the equipment.\u003c\/p\u003e\u003ch2\u003eWhat the AOC3D-460 Bundle Includes\u003c\/h2\u003e\u003ch3\u003eDual Aftercooler System\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eDual Belt Guard Aftercoolers (#BGAC2x2M):\u003c\/strong\u003e Two factory-mounted aftercoolers rated for 100 CFM combined — matched to dual C3 output. Cools both pump discharges before air enters the shared tank. Achieves approximately 65% water vapor reduction across full output range. Max 250 PSIG, max 350°F inlet temperature. Larger than the C2 duplex aftercooler set because the C3 produces proportionally more heat and moisture at 15 HP per pump head.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eAutomatic Drain System\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir-Operated Auto Drain (#ADVSM):\u003c\/strong\u003e Discharge-pressure-operated automatic drain with installation kit.

Provides scheduled purge cycles during idle periods. On a facility-scale system like a C3 duplex, the tank and separator volumes are significant — timed drains during off-hours are not optional.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHour Meters\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eHour Meter (#HRM460M):\u003c\/strong\u003e 460V-rated elapsed time meter. In a duplex setup, run-hour tracking lets you balance maintenance between both pump heads — when Pump A reaches its oil change interval, it comes down for service while Pump B carries the load. This is the entire operational value of the duplex arrangement.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eDual Control\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eDual Control (#DC3):\u003c\/strong\u003e Start\/stop and constant-speed load\/unload modes for the duplex system. At 15 HP per pump head, constant-speed unloading during production hours saves significant wear on starters and motor windings. The duty cycle implications of start\/stop vs. constant-speed are magnified at this power level.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eIntake Noise Silencers\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eIntake Noise Silencers (#SA100x2M):\u003c\/strong\u003e Two factory-mounted silencers, one per C3 pump head.

Two 485-lb cast iron pump assemblies on a large shared tank produce substantial vibration.
