FS-Curtis CA7.5-DUP — 7.5 HP (x2, Duplex) Air Compressor
The busiest 7.5 HP shops need both pump redundancy and the factory-installed air-quality accessories that keep a high-volume operation running without someone manually draining tanks between jobs.
The FS-Curtis CA7.5-DUP is a duplex two-stage reciprocating, ultra pack compressor rated for 7.5 HP (x2, Duplex) with a 120 gallon horizontal ASME tank, built for multi-bay shops and commercial operations that need compressed air on tap all day. The included Ultra Pack — factory-installed automatic tank drain and refrigerated air dryer — cuts down on the maintenance routine so your team spends less time babysitting the compressor and more time on paying work.
Who the CA7.5-DUP Is Built For
- ✅ A high-volume shop running 7.5 HP CA7.5 units that's already had a compressor failure shut down every bay at once, and won't risk that again without a second pump ready to take over
- ✅ Paint and finishing shops at the 7.5 HP tier where moisture in the air line is a real quality problem, needing both redundancy and factory air-quality accessories together
- ✅ A facility manager who's tired of scheduling maintenance downtime around a single compressor and wants one pump serviceable while the other keeps a demanding operation running
- ✅ An operator standardizing on FS-Curtis's top-tier Ultra Pack duplex configuration for the busiest or flagship location in a multi-bay group
- ✅ A shop planning real growth over the next year that would rather buy the fully-equipped duplex Ultra Pack now than upgrade twice as demand increases
What the CA7.5-DUP Is NOT Built For
- ❌ Single-bay or small shops — this is among the most expensive configurations in the CA7.5 line and is overkill for lighter demand
- ❌ Budget-conscious buyers — the base CA7.5-D duplex without Ultra Pack saves meaningfully if the accessories aren't needed yet
- ❌ Shops with limited floor space — the 120-gallon duplex tank has a larger footprint
What Makes the CA7.5-DUP Different
Commercial 2-Stage Pump
The CA7.5-DUP uses an E57 (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 46.4 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.
Ultra Pack Upgrades
Includes factory-installed automatic tank drain and refrigerated air dryer — upgrades that reduce maintenance and extend the life of the tank and pump versus a base-model compressor.
Power Requirements
Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Redundancy + factory accessories
- High-volume commercial shops
- Zero-downtime operations
- Single-bay / small shops
- Budget-first buyers
CA7.5-DUP vs. FS-Curtis CA10-D (10 HP Duplex, No Ultra Pack) — Which Compressor Is Right for Your Shop?
| Decision Point | CA7.5-DUP | FS-Curtis CA10-D (10 HP Duplex, No Ultra Pack) |
|---|---|---|
| Horsepower / Tank | 7.5 HP x2 / 120 Gal | 10 HP x2 / 120 Gal |
| CFM @ 175 PSI | 46.4 CFM | 68.4 CFM |
| Included accessories | Ultra Pack bundle (auto-drain/dryer per FS-Curtis config) | Standard configuration, no bundled accessories |
| Best fit | Shops wanting factory air-quality accessories at the 7.5 HP tier | Shops wanting more raw combined horsepower without the accessory bundle |
Choose the CA7.5-DUP for factory-installed air-quality accessories at a lower combined horsepower (and typically lower running cost). Choose the CA10-D if you want more raw CFM headroom and don't need the Ultra Pack accessories. Both stay inside Alamo’s catalog — call (817) 865-3707.
