FS-Curtis ML15-SH — 15 HP Air Compressor
A shop that needs the ML Series' 15 HP output but has an existing dryer or filtration system in place doesn't need to pay for factory Ultra Pack accessories duplicating what's already installed.
The FS-Curtis ML15-SH is a two-stage reciprocating compressor rated for 15 HP 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 ML15-SH Is Built For
- ✅ A commercial shop that's outgrown a 10 HP unit and needs 15 HP output, but doesn't need the Ultra Pack accessories yet
- ✅ An operation with an existing air dryer or filtration system already installed that doesn't need factory-bundled accessories duplicating in-place equipment
- ✅ A shop wanting the lower entry price of a base configuration with the option to add accessories later if demand changes
- ✅ A facility running several bays simultaneously needing sustained ~50 CFM output without paying for extras it won't use
- ✅ A shop standardizing on FS-Curtis's ML Series for parts and service commonality, starting with the base 15 HP tier
What the ML15-SH Is NOT Built For
- ❌ Shops whose demand is fully covered by a 10 HP unit — the ML10 line saves real money if 40 CFM is enough
- ❌ Shops wanting factory auto-drain/dryer accessories standard — the Ultra Pack (ML15-HUP) adds those, this base unit doesn't
- ❌ Shops needing single-phase power — this series is three-phase only
What Makes the ML15-SH Different
Commercial 2-Stage Pump
The ML15-SH uses a D97, 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 49.5 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.
- 49.5 CFM at 15 HP
- Lower entry price, no bundled accessories
- Multi-bay commercial shops
- Shops fully covered by 10 HP
- Single-phase-only electrical
ML15-SH vs. FS-Curtis ML10-SH (10 HP, 120 Gal Horizontal) — Which Compressor Is Right for Your Shop?
| Decision Point | ML15-SH | FS-Curtis ML10-SH (10 HP, 120 Gal Horizontal) |
|---|---|---|
| Horsepower / Tank | 15 HP / 120 Gal Horizontal | 10 HP / 120 Gal Horizontal |
| CFM @ 175 PSI | 49.5 CFM | 39.8 CFM |
| Included accessories | Standard configuration, no bundled accessories | Standard configuration, no bundled accessories |
| Best fit | Shops needing more CFM headroom at the same tank size | Shops whose demand is fully covered at 10 HP |
Choose the ML15-SH when 10 HP output is no longer enough for your shop's demand. Choose the ML10-SH if 40 CFM covers your actual draw — it costs meaningfully less. Both stay inside Alamo’s catalog — call (844) 480-6059.
