FS-Curtis ML5-DUP — 5 HP (x2, Duplex) Air Compressor
A paint shop's clear coat came back streaked with moisture last week, and the owner traced it to condensation building up in a tank nobody had drained in a month — that's exactly what the Ultra Pack's auto-drain and dryer are built to prevent, on top of the redundancy of a second pump.
The FS-Curtis ML5-DUP is a duplex two-stage reciprocating, ultra pack compressor rated for 5 HP (x2, Duplex) with a 120 gallon horizontal ASME tank, built for multi-bay shops and commercial operations that need compressed air on tap all day. The included Ultra Pack — factory-installed automatic tank drain and refrigerated air dryer — cuts down on the maintenance routine so your team spends less time babysitting the compressor and more time on paying work.
Who the ML5-DUP Is Built For
- ✅ A body or paint shop that's had a job come back with moisture streaks in the finish, tracing back to a tank that wasn't drained regularly, and wants the auto-drain and dryer handled automatically
- ✅ A multi-bay shop that wants both compressor redundancy AND factory air-quality accessories in one purchase instead of adding them piecemeal later
- ✅ An owner who's decided the Ultra Pack's maintenance savings are worth the price gap over the base ML5-D duplex
- ✅ A commercial operation running continuous multi-bay demand that needs 38.2 CFM combined output with dry, clean air delivered to every line
- ✅ A shop standardizing on FS-Curtis's top-tier ML5 configuration for its busiest or most quality-sensitive location
What the ML5-DUP Is NOT Built For
- ❌ Single-bay or lighter-demand shops — a simplex ML5-HUP covers the accessories at a lower price if redundancy isn't needed
- ❌ Budget-conscious buyers who don't need the extra accessories yet — the base ML5-D duplex saves money
- ❌ Shops with limited floor space — this is a larger-footprint duplex unit
What Makes the ML5-DUP Different
Commercial 2-Stage Pump
The ML5-DUP uses a D96 (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
Delivers 38.2 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.
Ultra Pack Upgrades
Includes factory-installed automatic tank drain and refrigerated air dryer — upgrades that reduce maintenance and extend the life of the tank and pump versus a base-model compressor.
Power Requirements
Single or Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Redundancy + factory accessories
- 38.2 CFM combined output
- Quality-sensitive multi-bay shops
- Single-bay / lighter-demand shops
- Budget-first buyers
