FS-Curtis ML15PLUS-D — 15 HP (x2, Duplex) Air Compressor
It's 2 AM on a night shift and the single compressor just tripped its breaker — every bay in the building goes quiet at once, techs standing around instead of working, and the plant manager is on the phone trying to figure out how many hours of production just got lost.
The FS-Curtis ML15PLUS-D is a duplex two-stage reciprocating compressor rated for 15 HP (x2, Duplex) with a 200 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 ML15PLUS-D Is Built For
- âś… A large commercial or fleet facility running multiple shifts where a compressor outage stops every bay at once, and the second pump keeping the line running pays for itself the first time it's needed
- ✅ An operation with continuous high-draw demand across several bays or booths simultaneously that a single pump — even at 15 HP — can't sustain alone
- âś… A facility that's grown past what a simplex unit can support and needs both maximum combined CFM (111.6) and the uptime insurance of a second pump
- âś… An operator who's had a single-compressor setup fail during a busy shift at a high-volume facility and doesn't want to repeat that
- âś… A commercial operation standardizing on FS-Curtis's ML15+ tier for the largest, highest-demand location in a multi-shop group
What the ML15PLUS-D Is NOT Built For
- ❌ Single-bay or mid-size shops where a simplex 15 HP unit (ML15+ SH) 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 200-gallon duplex tank has one of the largest footprints in the ML lineup
What Makes the ML15PLUS-D Different
Commercial 2-Stage Pump
The ML15PLUS-D uses a C89 (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 111.6 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
Three-Phase only, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- 111.6 CFM combined output
- Built-in pump redundancy
- Largest commercial facilities
- Single-bay / mid-size shops
- Tight floor space
ML15PLUS-D vs. FS-Curtis ML10-D (10 HP x2, Duplex, 200 Gal) — Which Compressor Is Right for Your Shop?
| Decision Point | ML15PLUS-D | FS-Curtis ML10-D (10 HP x2, Duplex, 200 Gal) |
|---|---|---|
| Horsepower / Tank | 15 HP x2 / 200 Gal Horizontal | 10 HP x2 / 200 Gal Horizontal |
| CFM @ 175 PSI | 111.6 CFM | 79.6 CFM |
| Redundancy | Duplex — two independent 15 HP pumps | Duplex — two independent 10 HP pumps |
| Best fit | Facilities needing the highest combined CFM with redundancy | Facilities whose demand is covered at the 10 HP tier |
Choose the ML15Plus-D for the highest combined CFM output with full pump redundancy. Choose the ML10-D if 79.6 CFM combined already covers your facility's demand — it costs less. Both stay inside Alamo’s catalog — call (844) 480-6059.
