The Castair C213H50 is a 2HP commercial air compressor on a horizontal 50-gallon tank — without a mounted starter. This is the base unit: pump, motor, tank, pressure switch, and safety valve assembled and ready for installation, but you supply and install the motor starting and overload protection. This configuration is right for shops with an existing motor control panel, or for electricians who want to install their own starter and overload relay rather than work with a pre-mounted unit.
The horizontal 50-gallon tank keeps the compressor low-profile. For most single-bay shops and light commercial applications, 2HP with a 50-gallon tank handles intermittent air tool use, tire inflation, and similar tasks without difficulty. This isn't a unit for running continuous-duty spray booths or high-demand multi-bay shops — for that, you'd want to step up to the 5HP or higher models.
Key Features
- 2HP Motor: Commercial-duty motor for shop and light industrial service — verify voltage requirements before ordering
- 50-Gallon Horizontal Tank: Horizontal low-profile design for shops with limited overhead clearance or under-bench installation
- No Mounted Starter: Base unit — you supply motor control and overload protection, or order the C213H50-S for the starter-included version
- Cast Air Reciprocating Pump: Cast iron construction for long commercial-duty service life
- Pressure Switch: Automatic cut-in/cut-out control — compressor starts when tank pressure drops and stops when it reaches the cut-out setting
- Safety Relief Valve: Tank-mounted safety valve for overpressure protection

C213H50 vs. C213H50-S — Which Should You Order?
The only difference is the starter. The C213H50-S includes a mounted magnetic starter with built-in overload protection — it's a self-contained electrical control system. The C213H50 (this unit) ships without that starter. Order the base unit if your electrician wants to integrate this compressor into an existing motor control center, or if you have specific starter requirements that don't match the factory-mounted option. Order the -S version if you want a complete, plug-and-play package.
C213H50 vs. C216V50 — Horizontal vs. Vertical
Both are 2HP / 50-gallon units. The C213H50 sits horizontally — longer and lower, fits under low ceilings, easier to move on casters. The C216V50 stands vertically — taller but smaller floor footprint, better for corner placement in tight shops. Performance is the same. Choose based on your space.
Applications
- Single-bay auto shops with intermittent air tool use
- Detail bays, alignment bays, and tire service
- Small shops needing a reliable commercial compressor
- Facilities with existing motor control infrastructure
