FS-Curtis ML20+ 200G Horiz 20HP Simplex Tank Electric Air Comp #ML20Plus-SH

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.
