FS-Curtis ML15-B — 15 HP Air Compressor
A facility with an existing central air system or receiver tank bank that needs 15 HP of additional pump capacity doesn't need another integral tank taking up space it doesn't have.
The FS-Curtis ML15-B is a two-stage reciprocating, baseplate compressor rated for 15 HP with no integral 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-B Is Built For
- ✅ A facility with an existing central air system or remote receiver tank that needs 15 HP of pump capacity, not another integral tank
- ✅ A shop replacing a failed pump on an existing baseplate-mounted system where matching the compact footprint matters
- ✅ An operator building or expanding a custom compressed-air setup with a separately-sized tank matched to actual facility demand
- ✅ A multi-compressor facility adding 15 HP of pump capacity to an existing tank bank
- ✅ A shop with tight mounting space where a compact baseplate unit fits where a full tank-mounted compressor won't
What the ML15-B Is NOT Built For
- ❌ Most standalone shops — if you don't already have a receiver tank, the tank-mounted ML15-SH or ML15-HUP is the simpler, complete solution
- ❌ Buyers who want a plug-and-play unit — a baseplate compressor still needs a tank, piping, and controls sourced separately
- ❌ Shops needing single-phase power — this unit is three-phase only
What Makes the ML15-B Different
Commercial 2-Stage Pump
The ML15-B 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.
- Pairs with existing receiver tank
- Compact baseplate footprint
- Custom air-system builds
- Shops without an existing tank
- Single-phase-only electrical
ML15-B vs. FS-Curtis ML15-SH (15 HP, 120 Gal Horizontal, Tank-Mounted) — Which Compressor Is Right for Your Shop?
| Decision Point | ML15-B | FS-Curtis ML15-SH (15 HP, 120 Gal Horizontal, Tank-Mounted) |
|---|---|---|
| Horsepower / Tank | 15 HP / No integral tank (baseplate) | 15 HP / 120 Gal Horizontal |
| CFM @ 175 PSI | 49.5 CFM | 49.5 CFM |
| Use case | Pairs with an existing receiver tank or custom system | Complete, ready-to-run tank-mounted unit |
| Best fit | Facilities with an existing tank/air system already in place | Shops wanting a complete standalone compressor |
Choose the ML15-B when you already have a receiver tank or central air system and just need the pump. Choose the ML15-SH for a complete, ready-to-run tank-mounted unit if you don't have an existing tank. Both stay inside Alamo’s catalog — call (844) 480-6059.
