FS-Curtis OL5 120G 5HP(2) Duplex Oil-less Air Compressor #OL5-D

FS-Curtis OL5-D — 5 HP (x2, Duplex) Air Compressor

A pharmaceutical clean room can't have its compressed air supply go down mid-batch — a single-pump failure isn't just a maintenance ticket there, it's a potential lost production run.

The FS-Curtis OL5-D is a duplex oil-less reciprocating compressor rated for 5 HP (x2, Duplex) with a 120 gallon horizontal ASME tank, a solid fit for shops and commercial operations that want dependable daily output first and can add accessories later if the job calls for it.

Who the OL5-D Is Built For

• ✅ A pharmaceutical, dental, or food-processing clean room where compressed air downtime mid-batch means a lost production run, not just an inconvenience
• ✅ A facility running continuous clean-air demand across multiple stations that a single oil-less pump can't sustain alone
• ✅ An operation that can service one pump during a shift without shutting down clean air supply to the rest of the facility
• ✅ A quality-critical operation that's had a single-pump oil-less unit fail and needs the redundancy built in this time
• ✅ A facility standardizing on FS-Curtis's oil-less OL Series duplex tier for its most contamination-sensitive line

What the OL5-D Is NOT Built For

• ❌ Smaller operations where a simplex OL5 already covers the clean-air demand
• ❌ Facilities needing single-phase power — this unit is three-phase only
• ❌ Budget-conscious buyers — duplex costs meaningfully more than simplex at the same HP

What Makes the OL5-D Different

Oil-Less Pump Design

The FS-Curtis OL5-D uses a W50 (x2), 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

At 12.3 CFM (x2) @ 100 PSI and up to 100 PSI, this compressor has the margin to supply clean, oil-free compressed air to contamination-sensitive processes and pneumatic equipment without the tank ever running low.

Power Requirements

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