Oil Free Air Compressors: Best Choice for Pure Air

Oil‑Free Performance for Maximum Efficiency and Minimal Operating Costs

Oil‑free technology offers numerous advantages and helps energy managers achieve valuable cost savings while simultaneously improving operational efficiency. Total life‑cycle costs decrease because companies save on air treatment and oil changes. Unlike oil‑lubricated systems, no additional equipment is required to remove oil from the air, such as oil separators, filtration systems, or condensate treatment.

CompAir’s portfolio delivers 100% oil‑free performance and includes both fixed‑speed and variable‑speed (RS) models, available in air‑ and water‑cooled versions, including:

• D15H (RS) to D37H (RS): Single‑stage, water‑injected models from 15 to 37 kW
• D37 (RS) to D160 (RS): Two‑stage models from 37 to 160 kW
• Ultima U55 to U160: Two‑stage premium‑efficiency models from 55 to 160 kW
• DX200 (RS) to DX355 (RS): Two‑stage models from 200 to 355 kW

This portfolio includes air‑ and water‑cooled models from 15 to 37 kW and is available in both fixed‑speed and regulated‑speed (RS) versions — ensuring maximum reliability, high energy efficiency, reduced operating costs, and high‑quality oil‑free compressed air.

Maximum Energy Savings Through Oil‑Free Technologies and Efficient Heat Recovery

Oil‑free solutions not only support ambitious sustainability goals but also unlock significant energy savings. Up to 94% of the energy required to operate a compressor is converted into heat — and with CompAir’s heat‑recovery systems, this valuable energy can be reused efficiently.

Companies can generate hot water up to 85 °C for process heat, space heating, or steam preconditioning, while significantly reducing their energy costs. Thanks to flexible retrofit options and with no impact on compressed air performance, many operations achieve payback on their investment in less than one year.

Users benefit from up to 8% more flow, up to 7% energy savings, and absolutely pure compressed air — available as fixed‑speed or variable‑speed models, and with air‑ or water‑cooling, from 200 to 355 kW.

Why the Oil‑Free DX Series Stands Out

• Modern compressor stage delivering up to 8% higher flow rate
• Up to 7% (FS) and 5% (RS) energy savings
• Premium variants for maximum efficiency
• Variable Speed models with up to 71% turndown
• Wide range of options and custom‑engineered solutions
• Optional heat recovery for additional savings
• iConn remote monitoring included as standard
• ASSURE service program for maximum operational reliability
