FS-Curtis ML30-DUP — 30 HP (x2, Duplex) Air Compressor
A 24/7 stamping plant lost an entire night shift last quarter when its single compressor pump failed at 2 AM — by the time a tech arrived at 6 AM, six hours of production were gone and the morning shift walked into a backlog that took two days to clear.
The FS-Curtis ML30-DUP is a duplex two-stage reciprocating, ultra pack compressor rated for 30 HP (x2, Duplex) with a 240 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 — means less time spent on manual upkeep and more consistent air quality without anyone having to remember a maintenance step.
Who the ML30-DUP Is Built For
- ✅ The single largest, most demanding industrial facilities in FS-Curtis's ML lineup, needing the highest combined CFM (204.4) with full pump redundancy and factory accessories together
- ✅ A 24/7 manufacturing plant that's had both a pump failure and a moisture-related quality escape in the same production year, solving both problems in one purchase
- ✅ An operation that's grown past what any simplex unit can support and needs the absolute top of FS-Curtis's ML Series lineup
- ✅ A flagship facility in a multi-plant operation where downtime costs are highest and every available safeguard is worth the investment
- ✅ A facility manager who's calculated that a single hour of production downtime costs more than the price difference between this and the base ML30-D
What the ML30-DUP Is NOT Built For
- ❌ The vast majority of shops and facilities — this is the single most expensive, highest-capacity unit in FS-Curtis's entire ML lineup
- ❌ Budget-conscious buyers — the base ML30-D duplex without Ultra Pack saves meaningfully if accessories aren't needed yet
- ❌ Facilities with limited floor space — this is the largest-footprint unit in the ML line
What Makes the ML30-DUP Different
Commercial 2-Stage Pump
The ML30-DUP uses a C98 (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
At 204.4 CFM @ 175 PSI and up to 175 PSI, this compressor has the margin to run impact wrenches, tire equipment, and paint tools without the tank ever running low.
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.
- Redundancy + factory accessories
- 204.4 CFM — highest in the ML line
- The largest industrial facilities
- Most shops / smaller facilities
- Budget-first buyers

| Decision Point | ML30-DUP | FS-Curtis ML30-D (Duplex, no accessories) |
|---|---|---|
| Horsepower / Tank | 30 HP x2 / 240 Gal Horizontal | 30 HP x2 / 240 Gal Horizontal |
| CFM @ 175 PSI | 204.4 CFM combined | 204.4 CFM combined |
| Redundancy + accessories | Duplex pumps + Ultra Pack bundle (auto-drain/dryer) | Duplex pumps, standard configuration |
| Best fit | The largest facilities wanting redundancy and factory accessories together | Large facilities wanting redundancy at a lower price |
Choose the ML30-DUP for the most fully-equipped, highest-capacity configuration FS-Curtis's ML Series offers. Choose the ML30-D for the same redundancy and CFM at a lower price if you don't need the Ultra Pack accessories. Both stay inside Alamo’s catalog — call (844) 480-6059.
