The Castair Aftercooler Option Bundle AOC2 230V is the complete factory-installed options package for Cast Air C2-series simplex compressors wired for 230V power. The C2 pump handles the 7.5 to 10 HP range — the workhorse industrial class for mid-size shops, body shops, and mechanical rooms. This bundle covers aftercooling, automatic drains, hour metering, dual control, and vibration isolation, all factory-installed and matched to your specific C2 unit. Ordering the complete bundle saves 10% over individual component pricing.
The C2 is a V4-configuration two-stage cast iron pump producing approximately 32–45 CFM at rated pressure depending on HP configuration. Running at around 895 RPM in the 7.5 HP setup, it's built for sustained industrial use. The #BGAC2M aftercooler in this bundle is rated to match that output — 50 CFM — not undersized.
What the AOC2 230V Bundle Includes
Aftercooler System
- Belt Guard Aftercooler (#BGAC2M): Factory-mounted, 50 CFM rated. Mounts within the belt guard and connects directly to pump discharge. Cools compressed air from pump discharge temperatures toward ambient, removing approximately 65% of water vapor before air reaches your lines, tools, and dryers. Operates to 250 PSIG max, 350°F max inlet temperature.
Automatic Drain System
- Air-Operated Auto Drain (#ADVSM): Operates off discharge pressure — no additional power needed. Purges condensate automatically on each compressor cycle. Includes mounting hardware and installation kit.
- Electronic Auto Drain (#SDV03M): 115V timer-controlled solenoid drain with strainer. Timed purge cycles keep condensate from building up during idle periods overnight or over weekends.
Hour Meter
- Hour Meter (#HRM75M): 230V-rated elapsed time meter. Tracks actual compressor run hours for proper maintenance scheduling. On a cast iron two-stage pump, maintenance intervals by hours run — not calendar time — is how you get 15,000+ hours of service life.
Dual Control
- Dual Control (#DC2): Provides both start/stop and load/unload constant-speed operation modes. Switch to constant-speed mode during sustained demand periods to reduce motor cycling; switch to start/stop during light-use periods to save energy. Both modes available without hardware changes.
Intake Noise Silencer
- Intake Noise Silencer (#SA100M): Factory-mounted intake silencer for the C2 pump. Reduces intake noise at the 895 RPM operating speed without restricting airflow or reducing CFM delivery.
Vibration Management
- Vibration Pads (#VP1004): Set of four rubber isolation pads. Protects the installation surface, tank connections, and distribution piping from vibration fatigue.
Right From Start Kit
- #RFS002: Factory startup consumables kit for the C2 pump. Includes the correct initial oil charge, break-in documentation, and service reference material. Correct startup procedure is critical on two-stage pumps.
Who Needs the AOC2 230V Bundle
This bundle is for shops installing a Cast Air C2 simplex compressor on 230V service — single-phase or three-phase 230V. If your facility runs 460V three-phase, see the AOC2-460 listing. Running a 230V motor on 460V will destroy the motor immediately.
Typical AOC2 customers: 3–6 bay auto repair shops, body shops, tire shops, light manufacturing, and commercial facilities where one compressor runs continuously during the workday. The C2's CFM output handles 3–5 simultaneous air tools at typical shop pressures.
AOC2 vs. Stepping Up or Down
- AOC1 (230V): C1 pump, 5 HP, ~22 CFM. Sufficient for small shops with 1–2 air tools. If you rarely run more than one tool at a time, C1 is adequate and cheaper to operate.
- AOC2 230V (this product): C2 pump, 7.5–10 HP, ~32–45 CFM. Right for shops with moderate, sustained air demand.
- AOC2D 230V: Duplex version — two C2 pumps on a shared tank with automatic backup. If you can't afford to lose air when a pump goes down for service, pay the premium for duplex.
- AOC3 230V: C3 pump, 15 HP, ~62 CFM. If you run continuous high-demand applications — plasma, sandblast, spray booth — the C2 won't keep up. Step to the C3.
