Cast Air T10324HC1-S Heavy Duty Shop Tandem Air Compressor — 10 HP, 230V/460V, Horizontal Commercial Tank, With Starter
The Cast Air T10324HC1-S is a tandem-configuration industrial air compressor built for shops that have outgrown single-pump units and need consistent, high-volume air delivery across multiple workstations. With two compressor pump units mounted on a single horizontal commercial tank, this machine delivers substantially more CFM than a comparably rated single-pump unit — without doubling your floor space. If your shop runs spray booths, sandblasting equipment, impact tools, and air-operated lifts simultaneously, this is the class of machine you need to look at.
Note: Manufacturer specifications for this model are pending — contact us at 866-217-0063 for confirmed CFM output, tank size, exact dimensions, and full phase requirements before ordering. We will verify current specs directly with Cast Air on your behalf.
What Is a Tandem Compressor?
A tandem compressor uses two separate pump assemblies connected to a common air receiver tank. Rather than one large pump working harder, two pumps share the workload. This design provides several real-world advantages over a single-pump unit of equivalent HP rating:
- Higher combined CFM output — Two pumps moving air simultaneously fills the tank faster and recovers faster under continuous demand.
- Redundancy — If one pump requires maintenance, the other can continue operating at reduced capacity, keeping critical shop operations running.
- Lower operating temperature per pump — Each pump runs cooler because neither is running at maximum stress continuously. Cooler operation extends pump life significantly in high-duty-cycle environments.
- Even wear distribution — Runtime hours are split across two pumps, which typically doubles the interval between pump services.
Who Is the 10 HP T10324HC1-S For?
At 10 total HP in a tandem configuration, this unit is well-matched for:
- Small to mid-size automotive shops running 2–4 bays with consistent but not extreme air demand
- Body shops using HVLP spray equipment, DA sanders, and spot blast systems
- Fabrication shops running plasma cutters with air-cooled torch assemblies and pneumatic grinders
- Fleet maintenance facilities servicing light to medium commercial vehicles
- Any operation that previously ran a single 5 or 7.5 HP unit and found it cycling too frequently or struggling to keep up during peak demand
If you are running a single compressor and it never fully recovers between jobs, a tandem unit at this HP level is typically the correct next step rather than jumping straight to a 20 HP single-pump machine.
Electrical Configuration
- Voltage: 230V/460V dual-voltage capable (confirm your available panel voltage before ordering)
- Phase: Single-phase (HC1 designation) — suitable for facilities that do not have 3-phase power available
- Starter included: Yes — the -S suffix confirms a motor starter is included with this unit. A magnetic starter protects the motor from overloads, phase loss, and voltage fluctuations. This is not an optional add-on here; it ships with the machine.
Before ordering, confirm your service panel can supply the required amperage. A 10 HP motor on 230V single-phase draws significantly higher amperage than the same HP on 460V 3-phase. Have your electrician verify your panel and breaker capacity.
Tank Configuration
- Orientation: Horizontal — lower center of gravity, more stable in busy shop environments, easier to move with a pallet jack if needed
- Grade: Commercial (HC designation) — built to ASME pressure vessel standards for continuous commercial use, not the lighter-duty tanks found on consumer or light contractor units
Starter Included — What This Means for Your Installation
The -S suffix on Cast Air models indicates the unit ships with a magnetic motor starter. This matters for several reasons:
- Magnetic starters provide overload protection — if the motor draws too much current, the starter trips before the motor burns out
- They allow remote on/off switching and panel integration
- Many insurance and code compliance requirements mandate properly rated starters on commercial compressors
- Without a starter, you would need to purchase and install one separately — typically $300–$600 in additional cost and labor
The starter being included with this unit means your electrician can land the power feed and be done. No separate starter sizing, ordering, or mounting required.
Cast Air T-Series Tandem Lineup — Where This Model Fits
Cast Air's T-series covers 10 HP through 30 HP in tandem configuration. The T10324HC1-S is the entry point of the tandem lineup:

- T15324HC1-S — 15 HP Tandem, 230V/460V, With Starter — $8,120.65
- T20324HC2-S — 20 HP Tandem, 230V/460V, With Starter — $9,460.25
- T20324HC3-S — 20 HP Tandem, 230V/460V 3-Phase, Large Tank, With Starter — $11,609.90

- T25312HC3-S — 25 HP Tandem, 230V 3-Phase, Large Tank, With Starter — $10,923.95
- T25324HC2 — 25 HP Tandem, 230V/460V, No Starter — $9,825.75
- T30312HC3-S — 30 HP Tandem, 230V 3-Phase, Large Tank, With Starter — $11,729.75
If your shop runs 5+ bays or heavy continuous production, stepping up to the 15 or 20 HP range is worth a conversation. Call us and we will help you size it correctly based on your actual tool list and duty cycle.
When Does a Shop Need This vs. Stepping Up or Down?
- This unit is right for you if you are running 2–4 bays, have 230V single-phase power available, and need more air than a single 5–7.5 HP unit can deliver without constant cycling.
- Step down to a single-pump unit if you are running one or two air tools intermittently — a tandem is overkill for light-duty use and the cost premium is not justified.
- Step up to the 15 or 20 HP tandem if you run spray booths alongside impact tools and lifts, or if you run more than 4 bays with simultaneous high-demand tool use.
- Consider 3-phase (T20324HC3-S or T30312HC3-S) if your facility has 3-phase power — the efficiency gains and lower amperage draw are significant at these HP levels.
