FS-Curtis CA5PLUS-DUP — 5 HP (x2, Duplex) Air Compressor
A high-volume shop that can't tolerate downtime AND can't tolerate moisture in the air line — where both failures cost real money — needs redundancy and air-quality accessories solved together, not as two separate purchases down the road.
The FS-Curtis CA5PLUS-DUP is a duplex two-stage reciprocating, ultra pack compressor rated for 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 CA5PLUS-DUP Is Built For
- ✅ A high-volume collision or fleet shop where a compressor failure during a rush shift means every bay stops billing, and moisture in the line has already cost a paint job — needing both problems solved in one unit
- ✅ An operation standardizing on the CA5+ platform's top tier for its busiest or flagship location, wanting maximum uptime insurance and factory-installed air-quality accessories together
- ✅ A shop planning real growth over the next year or two that would rather buy the fully-equipped duplex Ultra Pack now than upgrade twice as demand increases
- ✅ A facility manager who's had to schedule downtime around a single compressor's maintenance and wants one pump serviceable while the second keeps a demanding operation running
- ✅ A multi-bay paint and finishing operation where both continuous air volume and moisture-free air quality directly affect job outcomes, not just tool performance
What the CA5PLUS-DUP Is NOT Built For
- ❌ Single-bay or small shops — this is the most expensive configuration in the CA5+ line and is overkill for lighter demand
- ❌ Budget-conscious buyers — the base CA5Plus-D duplex without Ultra Pack saves meaningfully if accessories aren't needed yet
- ❌ Shops with limited floor space — the largest footprint in the CA5+ line at 84" long
What Makes the CA5PLUS-DUP Different
Commercial 2-Stage Pump
The CA5PLUS-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 37 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
Single or Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Redundancy + efficiency + accessories
- High-volume commercial shops
- Maximum headroom for growth
- Single-bay / small shops
- Budget-first buyers
CA5PLUS-DUP vs. Atlas AF9-120H (7.5 HP, 120 Gal Horizontal) — Which Compressor Is Right for Your Shop?
| Decision Point | CA5PLUS-DUP | Atlas AF9-120H (7.5 HP, 120 Gal Horizontal) |
|---|---|---|
| Horsepower / Tank | 5 HP x2 / 120 Gal Horizontal | 7.5 HP / 120 Gal Horizontal |
| CFM @ 175 PSI | 37 CFM | 22 CFM @ 175 PSI |
| Redundancy + accessories | Duplex pumps + Ultra Pack bundle (auto-drain/dryer) | Simplex, standard commercial configuration |
| Best fit | Highest-volume shops wanting redundancy and factory accessories together | Shops wanting a simpler single-pump setup at lower cost |
Choose the CA5+ DUP for the most fully-equipped, redundant setup in the CA5+ line. Choose the Atlas AF9-120H for a simpler single-pump 120-gallon setup at a lower price if you don't need redundancy or the Ultra Pack accessories. Both stay inside Alamo’s catalog — call (844) 480-6059.
