Oil-free compressors in action
When a petrochemical customer experienced a failure with their permanent breathing air system, GenAir provided a temporary oil-free compressed air solution to maintain safe working conditions during essential maintenance.
The results:
- Maintained a reliable supply of clean breathing air during critical works
- Helped minimise disruption to ongoing site operations
- Delivered a rapid, tailored solution for a demanding industrial environment
“Maintaining a safe supply of breathable air was our top priority. The temporary system was straightforward to install, performed exactly as required, and the support gave us confidence that our teams could continue working safely.”

Ask one of our teamWhat’s the difference between an oil-free screw compressor and a centrifugal compressor?
Oil-free screw compressors are highly versatile and suit a wide range of temporary industrial applications, including planned shutdowns, maintenance work and emergency cover.
Oil-free centrifugal compressors are designed for much higher air volumes, making them ideal for large industrial facilities, major shutdowns and continuous process applications where significant airflow is required.
If you’re unsure which is right for your project, our engineers can recommend the most suitable option.
Do you offer both diesel and electric oil-free compressors?
Yes.
Our fleet includes both diesel and electric oil-free compressors.
Electric compressors are often the most cost-effective option where a reliable mains power supply is available, while diesel compressors are ideal for remote sites or locations without sufficient electrical infrastructure.
How do I know whether I need a diesel or electric compressor?
The best choice depends on several factors, including:
- Whether mains power is available
- Expected operating hours
- Running costs
- Site access
- Mobility requirements
If you’re unsure, you can use our Diesel vs Electric Cost Calculator or speak to one of our engineers for advice.
Can you support emergency breakdowns?
Absolutely.
Our oil-free rental fleet is available for both planned projects and emergency situations. We understand that unexpected compressor failures can stop production, so we’ll work quickly to provide a suitable replacement and minimise disruption.
Can you support planned shutdowns?
Yes.
Many customers hire oil-free compressors during maintenance shutdowns, plant upgrades and temporary increases in demand. We’ll help you size the equipment correctly and coordinate delivery around your project schedule.
What size oil-free compressor do I need?
That depends on your required airflow, operating pressure and application.
Choosing equipment that’s too small can affect production, while oversizing can increase your hire and running costs.
Our team can recommend the right package based on your requirements.
Can you supply more than just the compressor?
Yes.
We can provide complete compressed air packages including:
- Air dryers
- Boosters
- Hoses
- Filters
- Ancillary equipment
Everything is designed to ensure your temporary compressed air system performs reliably from day one.
Is your equipment available nationwide?
Yes.
We deliver and support oil-free compressor rental projects throughout the UK, with three depots situated in England and Scotland. With additional capability across Europe following the expansion of our business.
What does the RTC acquisition mean for customers?
The acquisition of RTC Group has significantly expanded our oil-free rental fleet, particularly our range of high-volume centrifugal compressors.
It means customers can now access a broader range of oil-free equipment through a single supplier, whether they require a small temporary compressor or a large, high-capacity solution for a major industrial project.
How quickly can you supply an oil-free compressor?
This depends on the equipment required and your location, but we understand that many requests are time-critical.
Whether you’re responding to an emergency or planning a shutdown, contact our team and we’ll recommend the quickest and most appropriate solution for your application
