FS-Curtis ML15-HUP — 15 HP Air Compressor
A commercial shop that's maxed out the ML10's 40 CFM output during peak demand needs the extra headroom of a 15 HP pump, plus the factory-installed accessories that keep a high-volume operation running unattended.
The FS-Curtis ML15-HUP is a two-stage reciprocating, ultra pack compressor rated for 15 HP 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 ML15-HUP Is Built For
- ✅ A high-volume commercial shop that's maxed out a 10 HP unit's output during peak multi-bay demand and needs the extra CFM headroom of a 15 HP pump
- ✅ An operation that wants the auto-drain and refrigerated dryer built in from the factory rather than retrofitting accessories after the fact
- ✅ A commercial paint or finishing operation needing moisture-free air at higher CFM output across several booths running simultaneously
- ✅ A shop replacing an aging compressor that's started struggling under real daily multi-tool load before it fails during a busy week
- ✅ A facility standardizing on FS-Curtis's ML Series 15 HP tier for a higher-demand location in a multi-shop operation
What the ML15-HUP 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
- ❌ Budget-conscious buyers who don't need the extra accessories yet — the base ML15-SH saves money
- ❌ Shops needing single-phase power — this series is three-phase only
What Makes the ML15-HUP Different
Commercial 2-Stage Pump
The ML15-HUP 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.
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 only, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- 49.5 CFM at 15 HP

ML15-HUP vs. FS-Curtis ML10-HUP (10 HP, 120 Gal Horizontal, Ultra Pack) — Which Compressor Is Right for Your Shop?
| Decision Point | ML15-HUP | FS-Curtis ML10-HUP (10 HP, 120 Gal Horizontal, Ultra Pack) |
|---|---|---|
| Horsepower / Tank | 15 HP / 120 Gal Horizontal | 10 HP / 120 Gal Horizontal |
| CFM @ 175 PSI | 49.5 CFM | 39.8 CFM |
| Included accessories | Ultra Pack bundle (auto-drain/dryer) | Ultra Pack bundle (auto-drain/dryer) |
| Best fit | Shops needing more CFM headroom at the same tank size | Shops whose demand is fully covered at 10 HP |
Choose the ML15-HUP when 10 HP output is no longer enough for peak multi-bay demand. Choose the ML10-HUP if 40 CFM covers your shop's actual draw — it costs meaningfully less. Both stay inside Alamo’s catalog — call (844) 480-6059.
