FS-Curtis CA5-D — 5 HP (x2, Duplex) Air Compressor
A shop that can't afford any downtime — where a compressor going down mid-shift means the whole bay stops — needs a duplex setup with a second pump ready to take over, not a single point of failure.
The FS-Curtis CA5-D is a duplex two-stage reciprocating compressor rated for 5 HP (x2, Duplex) with a 120 gallon horizontal ASME tank, built for shops and commercial operations that need compressed air on tap all day without paying for accessories they don’t need.
Who the CA5-D Is Built For
- ✅ Multi-bay commercial shops where compressed air downtime directly costs billable hours
- ✅ Operations wanting built-in redundancy — if one pump needs service, the second keeps the shop running
- ✅ Shops with continuous, high-draw demand across several bays running simultaneously
- ✅ Buyers who've had a single-compressor setup fail at the worst possible time and don't want to repeat that
- ✅ Facilities planning to add more bays or techs and wanting headroom now rather than upgrading again later
What the CA5-D Is NOT Built For
- ❌ Single-bay or small shops where a simplex 5 HP or 7.5 HP unit already covers the air draw
- ❌ Budget-conscious buyers — duplex units cost significantly more than a simplex configuration at the same HP
- ❌ Shops with limited floor space — the 120-gallon duplex tank has a larger footprint than a single 80-gallon unit
What Makes the CA5-D Different
Commercial 2-Stage Pump
The CA5-D uses an E50 (x2), Cast-Iron, Two-Stage pump built for daily, all-day duty cycles — not a hobby-grade single-stage unit that struggles under continuous shop use.
CFM & Pressure Output
Delivers 34.8 CFM @ 175 PSI and holds pressure up to 175 PSI, enough headroom to run impact wrenches, tire equipment, and paint tools without the tank running dry.
Power Requirements
Single or Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Built-in pump redundancy
- Multi-bay continuous demand
- Zero-downtime commercial shops
- Single-bay / small shops
- Tight floor space
CA5-D vs. Atlas AF9 (7.5 HP, 80 Gal Commercial) — Which Compressor Is Right for Your Shop?
| Decision Point | CA5-D | Atlas AF9 (7.5 HP, 80 Gal Commercial) |
|---|---|---|
| Horsepower / Tank | 5 HP x2 / 120 Gal Horizontal | 7.5 HP / 80 Gal Vertical |
| CFM @ 175 PSI | 34.8 CFM | 20 CFM @ 175 PSI |
| Redundancy | Duplex — two independent pumps, built-in backup | Simplex — single pump, no built-in redundancy |
| Best fit | Shops needing uptime guarantees / continuous multi-bay draw | Shops wanting higher single-pump HP without duplex cost |
Choose the CA5-D when redundancy matters more than raw single-pump horsepower — one pump can fail and the shop keeps running. Choose the Atlas AF9 for a simpler simplex setup at a lower price point if uptime redundancy isn't a hard requirement. Both stay inside Alamo’s catalog — call (844) 480-6059.
