FS-Curtis ML7.5 80G Horiz 7.5HP Simplex Tank Ultra Pack Air Comp #ML7.5-HUP

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.
