FS-Curtis ML25-HUP — 25 HP Air Compressor
A quality manager at a large fabrication shop traced a batch of rejected parts back to moisture contamination in the air line, and the plant is done relying on manual tank draining across a facility running 82 CFM of continuous demand.
The FS-Curtis ML25-HUP is a two-stage reciprocating, ultra pack compressor rated for 25 HP with a 200 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 — handles two of the most common maintenance headaches automatically, so nobody on staff has to build it into a checklist.
Who the ML25-HUP Is Built For
- ✅ A quality manager at a large fabrication shop pulled a batch of rejected welded parts last month and traced the defect back to moisture contamination in the air line — the plant is done relying on a maintenance schedule that sometimes gets skipped during a busy week
- ✅ A facility running 82 CFM of continuous demand across plasma tables and pneumatic tooling watched a tank overflow past its drain interval twice in one quarter before the plant manager approved the auto-drain upgrade
- ✅ A plant engineer priced the base ML25-SH against this Ultra Pack version, ran the numbers on what one redone production batch costs from moisture contamination, and the accessory bundle paid for itself on paper before it was even installed
- ✅ A facility that outgrew its 20 HP compressor during a production line expansion needed both the higher HP tier and the accessories in one purchase to avoid buying twice within the same fiscal year
- ✅ A regional manufacturing group standardized every new install on the Ultra Pack tier after one uninsured moisture-damage claim at another plant made the accessory cost look cheap by comparison
What the ML25-HUP Is NOT Built For
- ❌ Facilities whose demand is fully covered by a 20 HP unit — the ML20/ML20+ line saves real money
- ❌ Budget-conscious buyers who don't need the extra accessories yet — the base ML25-SH saves money
- ❌ Facilities needing 120V/240V single-phase power — this unit is three-phase only
What Makes the ML25-HUP Different
Commercial 2-Stage Pump
The ML25-HUP 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
Rated for 82.4 CFM @ 175 PSI at pressure up to 175 PSI, with enough reserve to run impact wrenches, tire equipment, and paint tools without losing pressure mid-job.
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
Three-Phase only, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Factory air-quality accessories
- 82.4 CFM at 25 HP
- Large fabrication facilities
- Facilities covered by 20 HP
