Oil‑Free vs Oil‑Lubricated Compressed Air Systems?
A comprehensive range of industries and applications relies heavily on compressed air, which makes choosing the right compressor for your needs essential, particularly when you operate in production sensitive environments. This is because these applications require a much higher standard of compressed air to ensure safety, efficiency and quality. This includes food and beverage, pharmaceutical, and electronic manufacturing processes, where stringent standards are in place to ensure these manufacturing sites and the pneumatic tools and equipment that power them are pollutant‑free. For these environments, oil‑free compressors will be favoured due to their oil‑free operation and minimised risk of contamination, whereas for other less sensitive environments, oil‑lubricated systems and compressed air treatment may be preferred. Let’s take a quick look at the differences…
Oil‑free compressed air systems are typically the more eco‑conscious choice, as their oil‑free operation means there is no oil or oil‑contaminated condensate to dispose of, which is known to have an environmental impact. This prevents additional oil replacement costs and means that air treatment equipment, such as filtration systems, oil‑separators and condensate treatment, isn’t required to remove oil and condensate. Overall, this equates to reduced whole‑life‑cycle costs. However, oil‑lubricated compressors also offer benefits, including reliability, efficiency, design variety, and the ability to be installed alongside a variety of accessories and air tools to maximise profitability.
