A rotary screw compressor is a reliable and efficient type of air compressor that is ideal for various industries that require continuous operation. Rotary screw compressors can be oil-lubricated or oil-free, static or portable, giving you reliable operation, maximum efficiency, and high quality compressed air whenever and wherever you need it.
A rotary screw air compressor has many benefits and will bring many positive effects to your business operation whatever sector you operate in.
Energy efficiency – Air compressor operation takes a lot of energy consumption, so any reduction will make a big difference to your business’s energy costs. Rotary screw compressors use less energy to run than the old piston compressors for example, which means you can reduce your running costs and get an even greater ROI.
Low noise – As rotary screw air compressors have no mechanical elements, they’re the quietest compressors on the market. Many have noise levels that are roughly the same as normal conversations which means operators won’t need to wear ear protection as a result of working close to the compressor. Their quiet operation makes them ideal if you need them to be located at the point of use. Click here to find out more about our range of quiet air compressors.
Continuous airflow – Without a piston, rotary screw air compressors do not have a duty cycle and can therefore run continuously.
Work in extremes – With the right level of maintenance, screw compressors can withstand a higher level of challenging conditions and temperatures than piston or vane compressors.
Low maintenance – The rotary screw compressor has very few moving parts. Without valves, pistons, rings or connecting rods that are subject to wear and tear, there’s very little to go wrong. This means they don’t require a lot of maintenance and therefore have long service intervals, not only driving down servicing costs but also production downtime.
Longevity – Rotary screw compressors are built to last. Treated properly and with scheduled servicing and regular maintenance, they will work at full capacity for many years, making them a great investment for your business.
Smaller footprint – A rotary screw compressor is smaller than its piston compressor counterpart, meaning it takes up less space.

Contact Us or find out moreRotary screw compressors are best suited to heavy-duty industrial operations as well as sectors where there is a need for air purity.
Industries that need screw compressors because of their capacity to handle a heavy work load include construction, automotive, aerospace, manufacturing and production, food packaging etc.
The industries that depend on the purity of the compressed air which is produced by oil-free compressors include pharmaceuticals, food and drink, brewing, electronics, dental and healthcare.
It doesn’t matter what size of business you run or the amount of compressed air you need, we will have a high quality screw compressor that will be ideal for your needs and your budget. Check out our online shop or call us on +44 1992 932159 for more information and advice.
The success of the rotary screw air compressor lies in the screw element which is the central part of the basic design. Each screw compressor has male and female rotors which work together, rotating in different directions and at slightly different speeds, a process designed to trap air between them, compressing it as it moves down the shaft and into the compression chamber. When it reaches the right air pressure, the compressed air is then released through an outlet valve ready for use.
Oil-lubricated screw compressors are designed to operate on a 100% duty cycle, so you get a continuous supply of high pressure air. They are available in fixed and regulated speeds – from 2.2kW to 250kW, and are energy efficient – potentially achieving energy savings up to 25%. They do require regular oil changes, which are typically between 2000-3000 hours of operation; with the right maintenance, they have the potential to last a long time, capable of reaching 44,000 hours.
If you need a pure air supply, oil-free screw compressors are ideal. The rotors are coated with polytetrafluoroethylene (PTFE) – a high quality non-stick coating that is often referred to under the best known brand name Teflon® – which enables it to work effectively without lubrication. There is no danger of accidental air contamination with oil-free compressors, making them the only choice for the food and beverage, textile, electronics, chemical, and pharmaceutical industries. The absence of oil means they require little maintenance helping to keep your costs down, and also means they’re lighter than oil-lubricated versions, making them the ideal choice for portable compressors.

A rotary screw compressor is a clean, hard working compressor that provides continuous, high quality air. It uses two screw rotors to trap air and compress it, discharging clean air under pressure. It is more energy efficient, cleaner, lighter and a lot quieter than its equivalent piston air compressor.
The two compressor types we sell are rotary screw and rotary vane compressors. Both are capable of providing a supply of clean air, are quiet, energy efficient, easy to maintain, and long lasting. Rotary screw compressors are strong workhorses and are capable of continuous operation at high speed. Rotary vane compressors are reliant on centrifugal force and need to work at slower speeds – they have a maximum speed of around a third of that for a screw compressor. However, the slower speeds mean that the vane compressor has a longer lifespan, making them a good investment if your air compressor needs aren’t high. Call us on +44 1992 940498 to discuss the best compressor for your business.
With so few moving parts, the rotary screw compressor doesn’t need much maintenance, with the knock-on benefit that you will have less production downtime. However, oil-lubricated compressors will need the oil changing every 200-500 hours.
