Oil Free Screw Compressors
CompAir Ultima™
100% oil and silicone-free for clean air critical applications
Ultima™ is CompAir's groundbreaking oil-free PureAir screw compressor with a unique design. It is a brand new compressor range and it utilises a low pressure and high pressure dry screw airend. Each airend is individually driven by a variable speed, permanent magnet synchronous motor, offering exceptional levels of efficiency versus traditional oil-free technology.
CompAir is always improving the best products to be even better and more cutting edge.
Ultima™ - the real deal
Ultima compressors are 100% oil and silicone-free and meet ISO 8573-1 Class Zero (2010), making them the ideal choice for stringent oil-free applications within food and beverage, pharmaceutical, electronic and the automotive industries. What makes this compressor series unique is the lack of a gearbox. Ultima uses ultra high efficiency direct drive motors which replace the gearbox and the single motor, which optimise performance throughout the complete volume range, as the airends can be driven at different speeds dependant on the demand. With a single motor driving both airends together this is not possible. This is where Ultima is hard to beat.
The Ultima utilises an intelligent “digital gearbox“ design, which continuously monitors and independently adjust the speeds of each airend, ensuring maximum efficiency and pressure ratios at all times. When any regulated speed compressor gets to the minimum speed, it goes into idle run. For any compressor, this is wasted energy. Ultima uses 45% less energy in idle run than a conventional two-stage compressor and a 160kW compressor uses only 8 kW in idle run.
It is available with iConn remote monitoring. iConn is the all new and smart, proactive real-time monitoring service that delivers in-depth and real-time knowledge on the system to our compressed air users. It enables accurate production planning and total peace-of-mind protection, generating insight and statistics that keep users informed on performance, at the same time highlighting potential issues before they become a problem.
It's compact, low maintenance, high capacity, and exceeds industrial expectations.

🛠️ Key Benefits
✅ 100% Clean, Oil-Free Air
Ideal for strict air purity requirements in:
Food & Beverage processing
Pharmaceutical and medical industries
Electronics and semiconductor manufacturing
Laboratories and research facilities
…where even trace oil can compromise products or processes.
✅ Lower Maintenance
No oil changes, oil filters, or oil disposal needed—this reduces both downtime and maintenance costs.
✅ Environmental & Safety Advantages
No risk of oil leaks or oil waste disposal issues, making them more eco-friendly than conventional compressors.
✅ High Efficiency & Reliability
Modern designs, including variable speed drives (VSD), enhance energy efficiency and match air production to demand, further lowering operating cost.
📌 Typical Industrial Uses
Oil-free screw compressors are widely used where air purity is critical:
Food and beverage lines
Pharmaceutical and biotech production
Medical device manufacturing
Electronics & semiconductor fabrication
Textile & lab environments
…because oil contamination in these sectors can mean quality failures or regulatory violations.
