FS-Curtis ML20Plus-SH — 20 HP Air Compressor
A maintenance lead has logged three pressure drops this month during the plant's busiest hour, every one traced back to the same 20 HP compressor running flat out — the facility needs more real CFM at the same horsepower, not a bigger electrical bill.
The FS-Curtis ML20Plus-SH is a two-stage reciprocating compressor rated for 20 HP with a 200 gallon horizontal ASME tank, built to keep shops and commercial operations running on compressed air all day, in a lean base configuration that skips the extras.
Who the ML20Plus-SH Is Built For
- ✅ A production supervisor watched the shop's standard ML20 cycle nonstop through a rush order last month, with two stations losing pressure whenever a third came online — the ML20+'s C98 pump exists specifically so that stops happening
- ✅ A facility running three shifts noticed the compressor short-cycling every time a shift change overlapped two pneumatic lines starting up at once, and needed the larger 200-gallon reserve to absorb that spike instead of straining the pump
- ✅ A plant engineer pulled up the ML20-SH and ML20+ SH spec sheets side by side and picked the C98 pump specifically because the facility's peak-hour draw was already close to the standard unit's ceiling
- ✅ A facility manager working a tight capital budget this quarter chose the base ML20+ configuration over the Ultra Pack version, planning to add the dryer next fiscal year once the line's air-quality data justifies it
- ✅ A regional manufacturing group installed this tier at its busiest plant after a smaller ML20 at a sister facility kept needing manual pressure resets during peak production hours
What the ML20Plus-SH Is NOT Built For
- ❌ Facilities whose demand is fully covered by the standard ML20 — the ML20-SH costs less and saves floor space
- ❌ Shops wanting factory auto-drain/dryer accessories standard — the Ultra Pack (ML20Plus-HUP) adds those
- ❌ Facilities needing 120V/240V single-phase power — this unit is three-phase only
What Makes the ML20Plus-SH Different
Commercial 2-Stage Pump
The ML20Plus-SH uses a C98, 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 79.3 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.
- 79.3 CFM — highest 20 HP output
- 200-gallon reserve capacity
- High-demand production facilities
- Facilities covered by standard 20 HP
- Single-phase-only electrical
ML20Plus-SH vs. FS-Curtis ML20-SH (Standard, 20 HP) — Which Compressor Is Right for Your Shop?
| Decision Point | ML20Plus-SH | FS-Curtis ML20-SH (Standard, 20 HP) |
|---|---|---|
| Horsepower / Tank | 20 HP / 200 Gal Horizontal | 20 HP / 120 Gal Horizontal |
| CFM @ 175 PSI | 79.3 CFM | 65.1 CFM |
| Pump | C98 — higher-output pump platform | C89 — standard pump platform |
| Best fit | Facilities needing the highest CFM at 20 HP | Facilities where standard 20 HP output is sufficient |
Choose the ML20+ SH for the highest CFM output available at 20 HP and a larger tank reserve. Choose the standard ML20-SH if 65.1 CFM already covers your facility's demand — it costs less. Both stay inside Alamo’s catalog — call (844) 480-6059.
