Description
100% Oil-Free Air for Critical Work — Schulz 5 HP Oil-Free Air Compressor (20 CFM, 230V Single-Phase)
When even a trace of compressor oil will ruin the work — dental and medical air, food and beverage, electronics, pharmaceutical, and lab applications — an oil-lubricated compressor is a liability. The Schulz 5 HP oil-free air compressor (SKU 932.7540-0) compresses air with no oil in the pump, delivering genuinely oil-free air at 20 CFM displacement on a 60-gallon horizontal ASME tank. With 230V single-phase power it suits clinics, labs, and light production where air purity is non-negotiable. Call or text CET at 586-210-0555 before ordering to confirm it fits your application and air-quality requirement.

Common Questions
Frequently Asked Questions
- What does “oil-free” really mean here?
- The compression pump runs without oil in the cylinder, so no oil enters the air stream. That makes the air suitable for applications where oil contamination is unacceptable — medical and dental air, food and beverage, electronics, and laboratory use.
- What is the difference between displacement and FAD?
- Displacement (20 CFM) is the theoretical pump volume; FAD — Free Air Delivery (13.3 CFM at 120 psig) — is the actual usable air the compressor delivers. Size your tools against FAD, not displacement.
- 5 HP single-phase or three-phase — which do I need?
- This unit is 230V / 1-Phase / 60 Hz. It runs on common single-phase service found in most small shops and clinics. The matching three-phase version is the 932.7541-0. Unsure what your building has? Call or text 586-210-0555.
- Does oil-free mean maintenance-free?
- No — there is no pump oil to change, but you should still drain the tank, keep the intake filter clean, and inspect valves periodically. CET can supply maintenance parts; call or text 586-210-0555.
