FS-Curtis ML5-HUP — 5 HP Air Compressor
A one- or two-bay shop just lost a tire-shine job to rust flakes blown out of a compressor tank that never gets drained, and the owner wants the auto-drain handled without having to remember it every night.
The FS-Curtis ML5-HUP is a two-stage reciprocating, ultra pack compressor rated for 5 HP with an 80 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-HUP Is Built For
- ✅ A one- or two-bay shop that's had a paint or finishing job ruined by rust or moisture from a tank nobody remembers to drain, and wants the auto-drain handled automatically
- ✅ A shop stepping up from the CA-series 5 HP output into FS-Curtis's heavier-duty ML Series pump platform
- ✅ An owner who wants the refrigerated dryer factory-installed instead of retrofitting one after an air-quality problem
- ✅ A tight-footprint shop where the horizontal 80-gallon tank's lower clearance fits under a low ceiling or storage platform
- ✅ A shop standardizing on FS-Curtis's Ultra Pack tier for consistent accessories across its equipment
What the ML5-HUP Is NOT Built For
- ❌ Multi-bay shops needing more than roughly 19-20 CFM continuous — look at the ML7.5 or ML10 tier instead
- ❌ Budget-conscious buyers who don't need the extra accessories yet — the base ML5-SH saves money
- ❌ Shops needing built-in redundancy — this is a simplex (single-pump) unit; look at the ML5-DUP instead
What Makes the ML5-HUP Different
Commercial 2-Stage Pump
The ML5-HUP uses a D96, 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 19.1 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.
- Factory air-quality accessories
- Compact horizontal footprint
- 5 HP daily-duty output
- Multi-bay shops needing more CFM
- Shops needing redundancy
