FS-Curtis ML20 120G Horizontal 20HP Simplex Tank Electric Air Compressor #ML20-SH

FS-Curtis ML20-SH — 20 HP Air Compressor

A production line supervisor has watched a 15 HP compressor lose pressure every time the second and third pneumatic stations run at once — the facility just needs the extra CFM of the 20 HP tier, since maintenance already handles the tank drain manually and doesn't want that changed.

The FS-Curtis ML20-SH is a two-stage reciprocating compressor rated for 20 HP with a 120 gallon horizontal ASME tank, built for shops and commercial operations running compressed air all day, in a base configuration that keeps the upfront cost down.

Who the ML20-SH Is Built For

• ✅ A production facility that's watched a 15 HP compressor lose pressure under real multi-station demand and needs the extra CFM headroom of the 20 HP tier
• ✅ A facility with an existing air dryer or filtration system already installed, not needing factory-bundled accessories duplicating what's in place
• ✅ An operation wanting the lower entry price of a base configuration with the option to add accessories later if demand changes
• ✅ A commercial shop replacing an aging compressor that's started struggling under real daily multi-tool load
• ✅ A facility standardizing on FS-Curtis's ML Series for parts and service commonality, starting at the base 20 HP tier

What the ML20-SH Is NOT Built For

• ❌ Smaller shops whose demand is fully covered by a 10-15 HP unit — the ML10/ML15 line saves real money if 65 CFM isn't needed
• ❌ Shops wanting factory auto-drain/dryer accessories standard — the Ultra Pack (ML20-HUP) adds those, this base unit doesn't
• ❌ Facilities needing 120V/240V single-phase power — this unit is three-phase only

What Makes the ML20-SH Different

Commercial 2-Stage Pump

The ML20-SH uses a C89, 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

Puts out 65.1 CFM @ 175 PSI, holding up to 175 PSI — enough capacity to run impact wrenches, tire equipment, and paint tools without the compressor falling behind.

Power Requirements

Three-Phase only, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
