{"title":"Compressors - Industrial Series","description":"\u003cp\u003eIf you're sourcing an industrial air compressor that'll run a full shift without complaint, Cast Air's Industrial Series is worth a hard look. Ranging from 5 HP to 25 HP with tank options from 80 to 240 gallons, this is the core lineup Cast Air has been building in Spicer, Minnesota since 1991 — all cast iron, all American-made, engineered for auto shops, body shops, fleet maintenance bays, and industrial facilities that can't afford downtime.\u003c\/p\u003e\n\n\u003cp\u003eEvery pump in this series is cast iron two-stage, running at low RPM (590–1000 RPM depending on model) for cooler operating temps, longer pump life, and better oil retention. Single-phase and 3-phase configurations are available across the lineup, so whether you're wiring into a standard 230V shop circuit or a 460V industrial panel, there's a spec that fits. These aren't made-offshore machines re-badged for North American sale — Cast Air has been family-owned and manufacturing in Minnesota for over 30 years.\u003c\/p\u003e\n\n\u003cp\u003eFor shops that need redundancy or can't risk a single-point compressor failure, take a look at the \u003ca href=\"\/collections\/cast-air-duplex\"\u003eCast Air Duplex Series\u003c\/a\u003e — alternating dual-pump systems built on the same cast iron platform.

This is the highest-output 15HP option in the Castair industrial line, delivering 50.2 CFM at 175 PSI. Compared to the 15HP C2 configuration (898 RPM, 45.3 CFM at 175 PSI), the C3 pump runs slower, outputs more air, and weighs substantially more — 1,185 lbs versus 980 lbs.

This is not a consumer or commercial unit dressed up in industrial clothing — it is a purpose-built shop compressor engineered for continuous-duty applications where downtime is not acceptable. At 795 RPM, this machine runs quieter and cooler than high-speed competitors, which translates directly into longer pump life and lower maintenance costs over the years.\u003c\/p\u003e\n\n\u003cp\u003eThe -S suffix means this unit ships with an aftercooler mounted to the belt guard, which reduces discharge air temperature before it enters the tank. Cooler compressed air means less moisture carryover, which matters if you are running air-powered tools, spray guns, or any process that is sensitive to water contamination. If you are in a shop environment where air quality affects your work — body work, painting, sandblasting, precision air tools — the aftercooler pays for itself quickly.\u003c\/p\u003e\n\n\u003cp\u003eThis is the heavy-duty 15HP vertical option in Castair's Industrial Series lineup. The vertical tank configuration saves floor space compared to the horizontal equivalent, making it a practical choice for shops where square footage is at a premium.

The C2 pump at 898 RPM delivers 45.3 CFM at 175 PSI, which is roughly 30% more output than a 10HP C2 unit at the same pressure.

This is the large-pump, slow-RPM version of the 10HP 3-phase line — the C3 pump configuration means a bigger cast iron pump running at just 570 RPM instead of 758 RPM, which translates directly into lower operating temperatures, less wear, and a noticeably quieter shop. The 120-gallon vertical tank keeps your floor footprint tight while giving you the storage capacity to handle intermittent high-demand tools without constant pump cycling. The included magnetic motor starter (the -S suffix) means this unit ships ready to wire and run.\u003c\/p\u003e\u003ch2\u003eWho Needs This Compressor\u003c\/h2\u003e\u003cp\u003eThis is a shop-grade machine for busy automotive, truck, and general industrial shops running multiple air tools at once. If your shop is running 3–4 impact wrenches, spray guns, sandblasters, or air-powered lifts simultaneously on 3-phase power, the I10312VC3-S delivers 35.0 CFM at 175 PSI — enough to keep those tools fed without struggling. The vertical 120-gallon tank is the right call for shops where floor space is tight but ceiling height is available.\u003c\/p\u003e\u003cp\u003eIf you are on single-phase power, look at the I10112VC3-S instead.

The cast iron C2 two-stage pump runs at 758 RPM, producing 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI. At 860 lbs and 69 x 24 x 50 inches, it is 15 lbs lighter than the single-phase equivalent (I10112HC2-S at 875 lbs) — three-phase motors are physically smaller for the same output.\u003c\/p\u003e\n\n\u003cp\u003eIf your facility has three-phase power, there is no practical reason to run a single-phase motor on a 10 HP compressor. Three-phase motors run cooler under load, start with less inrush current, require less derating at high ambient temperatures, and outlast single-phase motors in hard continuous service.

The horizontal tank measures 64x20x46 inches and sits at around 46 inches tall, which is the right choice when you need to tuck a compressor under a shelf, against a low-clearance wall, or in a service bay where a vertical tank would be in the way. At 770 lbs it is a serious machine — this is not a light-duty compressor dressed up in industrial paint.\u003c\/p\u003e\u003ch2\u003eWho Needs This Compressor\u003c\/h2\u003e\u003cp\u003eBusy automotive shops, truck service facilities, and production shops running on 3-phase power that need a horizontal-tank machine. The I1038HC2-S delivers 35.0 CFM at 175 PSI — enough to run 3–4 impact wrenches, a paint gun and tools simultaneously, or to keep a sandblasting cabinet supplied for extended sessions. The 80-gallon tank provides good buffer storage so the pump is not short-cycling under intermittent high-demand tools.\u003c\/p\u003e\u003cp\u003eIf you need more storage and have the ceiling height, the vertical I1038VC2-S occupies a smaller floor footprint (40x24 inches vs 64x20 inches) while holding the same 80 gallons at similar weight.

An 80-gallon tank at 175 PSI holds substantially more reserve than a 30-gallon tank — meaning your compressor runs less often, the motor starts fewer times per hour, and tools don't starve during a burst demand. For a shop running two to three bays with air impacts, ratchets, and tire equipment, the 80-gallon tank is the right balance between reserve volume and footprint.\u003c\/p\u003e\n\n\u003ch3\u003ePump

The C3 pump runs at 570 RPM — significantly slower than the 758 RPM C2 pump — delivering the same 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI with less heat, less noise, and less wear per operating hour.

The C3 pump runs at 570 RPM — 188 RPM slower than the C2 variant. Output is unchanged at 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI. The price is more weight (1,040 lbs versus 875 lbs for the C2) and a higher purchase price. The benefit is a pump that runs noticeably cooler, wears measurably slower, and sounds quieter than the already-slow C2.\u003c\/p\u003e\n\n\u003cp\u003eIf you are buying one compressor and expecting to still be running it in 2045, this is the configuration.

This unit pairs Castair's cast iron C2 two-stage pump — running at 758 RPM — with a 120-gallon horizontal ASME-coded tank and a factory-mounted magnetic motor starter. Output is 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI. The horizontal tank configuration works well in shops where ceiling height is limited or where a low-profile unit tucks under a workbench or along a wall.\u003c\/p\u003e\n\n\u003cp\u003eThe '-S' suffix means the magnetic starter is factory-mounted and wired.

Output is 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI — enough to run a busy auto shop comfortably on single-phase 230V power. The vertical tank configuration is 44 inches wide by 30 inches deep by 75 inches tall and weighs 875 lbs. If your shop has open wall space and limited floor depth, a vertical tank uses that space more efficiently than a horizontal unit of equivalent capacity.\u003c\/p\u003e\n\n\u003cp\u003eThe magnetic starter is included and factory-wired.

The cast iron C2 two-stage pump runs at 758 RPM, producing 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI. At 780 lbs and 64 x 20 x 48 inches, this is the most compact 10 HP horizontal option in the Cast Air Industrial lineup — fits where a 120-gallon unit will not, and still delivers full 10 HP output.\u003c\/p\u003e\n\n\u003cp\u003eThe 80-gallon versus 120-gallon decision comes down to your shop's demand pattern. If your tools run intermittently with recovery time between cycles, 80 gallons is enough. If you are running multiple tools continuously without significant off-time, 120 gallons keeps recovery times from becoming a production constraint.

The C2 cast iron two-stage pump runs at 758 RPM and produces 45.0 CFM at 0 PSI and 35.0 CFM at 175 PSI. The vertical tank stands 74 inches tall on a 32 x 24 inch footprint and weighs 780 lbs. This is the smallest-footprint 10 HP option in the Cast Air Industrial lineup — 32 x 24 inches is significantly tighter than the 64 x 20 horizontal equivalent, and the narrow footprint makes it easier to position against a wall or in a corner.\u003c\/p\u003e\n\n\u003cp\u003eThe magnetic motor starter is factory-mounted and wired.

Full cast iron pumps with steel connecting rods (not the cheap aluminum rods found on most competitors). Tapered roller bearings instead of plain bushings.
