Castair I7112VC2-S

Castair I7112VC2-S — Industrial Air Compressor, 120-Gallon Vertical Tank

The Castair I7112VC2-S is a large-capacity industrial air compressor configured with a vertical 120-gallon tank — the right choice when floor space is limited but air storage capacity cannot be compromised. Like the horizontal I7112HC2-S, this unit is built around a 7 HP class motor, a cast iron pump in configuration 2, and ships with a factory-mounted magnetic starter for direct hardwired installation.

Manufacturer specifications for CFM, PSI, motor amperage, and physical dimensions are pending confirmation. Contact us before purchasing if you need to verify air output against your shop's demand calculations.

What the I7112VC2-S Is Built For

\n
• Floor-space-constrained shops: A vertical tank uses a significantly smaller floor footprint than a horizontal unit of the same capacity.
\n
• High air demand environments: 120-gallon receiver capacity provides substantial air storage to handle demand spikes across multiple tools or bays running simultaneously.
\n
• Cast iron pump durability: Cast iron construction is suited for longer run cycles and higher duty demands compared to aluminum pump alternatives.
\n
• Factory magnetic starter: The -S designation means the magnetic starter is factory-mounted and pre-wired. No separate panel sourcing or field assembly required.
\n
• Configuration 2 pump: The C2 designation reflects Cast Air's higher RPM pump configuration within this series. Contact us to confirm CFM output specifications versus the C1 variant.

Vertical Tank Considerations

\n
• Floor footprint: Vertical tanks take up less floor space — a meaningful advantage in production shops where every square foot counts.
\n
• Stability: Tall vertical tanks require secure installation. Anchoring to a wall or floor is strongly recommended.
\n
• Condensate drainage: Drain valves on vertical tanks require attention to placement. Establish a regular drain schedule to prevent water accumulation in the tank.
\n
• Horizontal alternative: If floor space is not a constraint, the I7112HC2-S horizontal configuration is slightly easier to drain and has a lower center of gravity.

120-Gallon vs. 80-Gallon: When You Need the Larger Tank

\n
• If your air demand is intermittent — one lift, occasional impact tools, tire service — the I718 series (80-gallon) handles that load at lower cost.
\n
• If you are running continuous paint, sandblasting, or three or more bays pulling air simultaneously, the 120-gallon receiver maintains pressure more consistently under sustained load.
\n
• Larger receivers also extend compressor duty cycles, reducing motor and pump wear over time.

Installation Notes

\n
• Requires dedicated hardwired electrical circuit — confirm amperage and wire gauge requirements with your electrician before ordering.
\n
• Vertical installation requires floor anchoring or wall securing for safe operation.
\n
• Cast iron pump requires manufacturer-specified break-in procedure and scheduled oil changes. Follow the manual.
