FS-Curtis OL15 120G Horiz 15HP Simplex Oil-less Air Comp #OL15

FS-Curtis OL15 — 15 HP Air Compressor

A food-processing plant running three packaging lines off one 10 HP oil-less compressor started seeing pressure drop across all three stations during the morning rush, and the maintenance team confirmed the unit was simply maxed out for the plant's current output.

The FS-Curtis OL15 is a simplex oil-less reciprocating compressor rated for 15 HP with a 120 gallon horizontal ASME tank, built to deliver reliable, all-day compressed air for shops and commercial operations at a straightforward entry price.

Who the OL15 Is Built For

• ✅ A food-processing plant's maintenance lead pulled a 10-year-old OL10 out of service last month after it started losing output under the plant's now-expanded three-line demand, and needed a single pump big enough to cover it without adding a second unit
• ✅ A pharmaceutical packaging facility running one central clean-air line into four filling stations found the OL10 tier came up short during a scheduled production surge, and the plant engineer chose the highest simplex capacity available rather than moving straight to duplex redundancy
• ✅ A dental-implant manufacturer replacing an aging oil-less unit that had started showing reduced CFM under real daily multi-line load needed the largest single-pump option before that unit failed outright mid-production
• ✅ A quality auditor at a contract manufacturer flagged the facility's older lubricated backup compressor as a contamination risk during an FDA inspection, and the plant standardized its main and backup lines on FS-Curtis's oil-less OL Series at the largest single-pump tier
• ✅ A plant engineer sizing a new clean-air system for a facility expansion picked the OL15 specifically because it was the largest simplex configuration that still fit the mechanical room's existing footprint

What the OL15 Is NOT Built For

• ❌ Smaller facilities where the OL5, OL7.5, or OL10 tier already covers the clean-air demand
• ❌ Facilities needing single-phase power — this unit is three-phase only
• ❌ Operations needing redundancy — this is a simplex (single-pump) unit; look at the OL15-D duplex instead

What Makes the OL15 Different

Oil-Less Pump Design

The FS-Curtis OL15 uses a W15, Oil-less Design — a 100% dry-crankcase design built for continuous duty without oil, so there's no oil-change maintenance and zero risk of oil carryover into the compressed air line.

CFM & Pressure Output

Rated for 52 CFM @ 100 PSI at pressure up to 100 PSI, with enough reserve to supply clean, oil-free compressed air to contamination-sensitive processes and pneumatic equipment without losing pressure mid-job.

Power Requirements

Three-Phase only, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
