The Castair C213H50-S is a 2HP commercial air compressor on a horizontal 50-gallon tank with a mounted magnetic starter included. The horizontal tank configuration keeps the overall height low — useful in shops with limited overhead clearance or when you need the compressor to fit under a workbench or mezzanine. The mounted starter means the electrical control is already integrated into the unit — you run power to the starter, not directly to the motor, and you get built-in overload protection for the motor.
This is a complete compressor package minus only the power connection. The C2 pump series paired with a 50-gallon horizontal tank is a solid fit for single-bay shops, detail bays, and light commercial applications where demand is moderate and continuous-run isn't required.
Key Features
- 2HP Motor: Single-phase commercial motor — verify voltage requirements (115V or 230V) for your electrical service before ordering
- 50-Gallon Horizontal Tank: Horizontal orientation keeps the compressor profile low; 50 gallons provides adequate reserve for intermittent tool use
- Mounted Magnetic Starter: Integrated motor starter with overload protection — connect power to the starter rather than directly to the motor
- Cast Air Pump: Cast iron reciprocating pump built for commercial-duty service life
- Complete Package: Tank, pump, motor, starter, and pressure controls assembled — connect power and air line and run
- Pressure Switch Control: Automatic start/stop based on tank pressure — set your cut-in and cut-out points

Horizontal vs. Vertical Tank — Which Is Right?
The horizontal C213H50-S and the vertical C216V50-S serve the same 2HP / 50-gallon application in different physical footprints. The horizontal tank is longer and lower — it rolls on casters easily and fits under low ceilings, but takes up more floor length. The vertical tank (C216V50-S) stands tall with a smaller floor footprint — better for corner installations in tight spaces. Same pump and motor, different tank orientation. Choose based on your available space.
With Starter (-S) vs. Without Starter
The C213H50-S includes the mounted magnetic starter. The C213H50 (same unit, no "-S") ships without the starter — you supply your own motor control. If you're installing this compressor in a facility with an existing motor control center or if your electrician wants to use specific starter hardware, the base unit without the mounted starter gives you that flexibility. If you want a complete, self-contained package, order the -S version.
Applications
- Single-bay auto repair shops with moderate air demand
- Detail shops running spray guns and air tools intermittently
- Small fabrication shops with general pneumatic tool use
- Light commercial and contractor applications
