FS-Curtis ML7.5-HUP — 7.5 HP Air Compressor
A multi-bay shop stepping up to 7.5 HP has also had a moisture problem in the past and doesn't want to gamble on it happening again — the factory-installed dryer and auto-drain come standard here instead of being an afterthought.
The FS-Curtis ML7.5-HUP is a two-stage reciprocating, ultra pack compressor rated for 7.5 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 ML7.5-HUP Is Built For
- ✅ A three-bay shop upgraded from a 5 HP compressor last year but skipped the accessories to save money, then had a paint job come back with moisture spots two months later — this time around, the owner is buying the Ultra Pack from the start instead of learning that lesson twice
- ✅ A single tech running the shop solo on weekends kept forgetting to open the tank drain before locking up Friday night, and came in Monday to a rusty valve — the auto-drain removes that task from anyone's mental checklist entirely
- ✅ An owner sat down with two quotes side by side — the base ML7.5-SH and this Ultra Pack version — and ran the math on how much a single redone paint job costs versus the accessory upsell, then bought the HUP
- ✅ A shop squeezed into a strip-mall unit with a low drop ceiling needed the horizontal tank's shorter overall height just to get the compressor through the service door, let alone find floor space for it
- ✅ A regional franchise standardized every location on the Ultra Pack tier after one store's uninsured moisture damage claim made the accessory cost look cheap by comparison
What the ML7.5-HUP Is NOT Built For
- ❌ Shops whose demand is fully covered by a 5 HP unit — the ML5 line saves real money if 19 CFM is enough
- ❌ Budget-conscious buyers who don't need the extra accessories yet — the base ML7.5-SH saves money
- ❌ Shops needing built-in redundancy — this is a simplex (single-pump) unit; look at the ML7.5-DUP instead
What Makes the ML7.5-HUP Different
Commercial 2-Stage Pump
The ML7.5-HUP uses a C79, 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 28.7 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
- 7.5 HP daily-duty output
- Shops fully covered by 5 HP
- Shops needing redundancy
ML7.5-HUP vs. FS-Curtis ML7.5-VUP (7.5 HP, Vertical tank, Ultra Pack) — Which Compressor Is Right for Your Shop?
| Decision Point | ML7.5-HUP | FS-Curtis ML7.5-VUP (7.5 HP, Vertical tank, Ultra Pack) |
|---|---|---|
| Horsepower / Tank | 7.5 HP / 80 Gal Horizontal | 7.5 HP / 80 Gal Vertical |
| CFM @ 175 PSI | 28.7 CFM | 28.7 CFM |
| Tank orientation | Horizontal — lower overall height | Vertical — smaller floor footprint |
| Best fit | Shops with low ceiling clearance | Shops with tight floor space but taller ceilings |
Choose the ML7.5-HUP when ceiling clearance is limited and you want a lower-profile unit. Choose the ML7.5-VUP when floor space is the bigger constraint and you have the ceiling height for a vertical tank. Both stay inside Alamo’s catalog — call (844) 480-6059.
