FS-Curtis CC Series

The CC series is a line of climate-control air compressors in the smaller horsepower range, roughly 0.75 HP to 5 HP, on 30 to 120 gallon tanks, in both simplex and duplex configurations. They are built for HVAC and climate-control service applications rather than general heavy shop duty.

These units are configured for the air supply needs of HVAC and refrigeration service work, where demand is lighter and more intermittent than a busy automotive bay. They are not a substitute for a general-purpose shop compressor sized to run impact tools continuously.

Simplex models have one pump and motor; duplex models have two on a shared tank. Duplex gives redundancy — if one pump is down the other still supplies air — and lets one pump handle light demand while both handle peak. Duplex costs more and needs more electrical capacity.

Generally no. At 0.75 to 5 HP these units are sized for light, intermittent duty. An automotive bay running impacts, ratchets, and tire equipment will outrun their recovery. Look at the CA, CT, or ML series for that application.

The smaller units in this series are typically available in single-phase configurations suitable for buildings without three-phase service, with larger models moving to three-phase. Confirm voltage, phase, and amperage on the specific model against your available service.

Yes, if the air contacts anything sensitive. Even light-duty compressors produce saturated discharge air. A minimum of moisture separation and filtration should be fitted; refrigerated drying is appropriate where the air must stay dry through the distribution piping.

Drain the tank daily, change pump oil and inlet filter at the stated interval, and inspect belts on belt-drive models. On duplex units, confirm both pumps are running and alternating correctly — a failed pump on a duplex can go unnoticed because the other one keeps supplying air.
