FS-Curtis ML25 240G 25HP(2) Duplex Tank Mounted Electric Air Compressor #ML25-D

FS-Curtis ML25-D — 25 HP (x2, Duplex) Air Compressor

A large manufacturing facility running continuous multi-shift production off one 25 HP compressor had a pump bearing fail during a night shift, and the entire line sat idle for eight hours waiting on an emergency repair — that's the exact scenario a second independent pump exists to prevent.

The FS-Curtis ML25-D is a duplex two-stage reciprocating compressor rated for 25 HP (x2, Duplex) with a 240 gallon horizontal ASME tank, built to deliver reliable, all-day compressed air for shops and commercial operations at a straightforward entry price.

Who the ML25-D Is Built For

• ✅ A large manufacturing facility running continuous multi-shift production had a pump bearing seize during a night shift last year, and the line sat idle for eight hours before an emergency repair crew arrived
• ✅ A facility running plasma tables and pneumatic tooling across six stations at once watched a single 25 HP pump strain to keep pace during a rush order, with two stations losing pressure simultaneously
• ✅ A maintenance supervisor pulled a pump for scheduled bearing service mid-shift last quarter and needed the second pump to keep the floor running instead of shutting down air to every station
• ✅ A facility engineer ran the numbers on the Ultra Pack duplex against this base configuration and decided the plant's existing dryer setup made the extra cost unnecessary for now
• ✅ A regional manufacturing group installed this exact duplex tier at its highest-volume plant after a smaller simplex unit at a sister facility couldn't keep up during a demand spike

What the ML25-D Is NOT Built For

• ❌ Smaller facilities where a simplex ML25-SH or HUP already covers the air draw
• ❌ Shops wanting factory auto-drain/dryer accessories standard — the Ultra Pack (ML25-DUP) adds those, this base unit doesn't
• ❌ Facilities with limited floor space — the 240-gallon duplex tank has a large footprint

What Makes the ML25-D Different

Commercial 2-Stage Pump

The ML25-D uses a C98 (x2), 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

Output holds at 164.8 CFM @ 175 PSI, up to 175 PSI, which is enough to run impact wrenches, tire equipment, and paint tools through a full shift without the pump running constantly.

Power Requirements

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