Lubricated rotary screw air compressors are used every day across the world in a wide variety of applications, from the small 2 kW model you may find in a garage or workshop, up to large 250 kW models where multiple machines used together can power a whole factory production line. Critical tasks like air tools, packaging, welding along with many other factory processes rely on compressed air & these models can generate the onsite air you need, on demand, when & where it's needed, each installation is sized according to your production needs.
You can read more about the technology used in these compressors here, or the different applications they serve here.
Please select a kW size below, if you need help sizing your air requirements please get in touch with us directly.
One of the main benefits of choosing a screw compressor is that, in comparison with piston compressors, there are no valves or other mechanical forces that can cause the compressor to become unbalanced. This allows a screw compressor to provide quality air at high operational speeds with a larger flow rate, without compromising on compact design!
Aside from premium energy efficiency, some other reasons to choose a screw compressor include:
CompAir's rotary screw range operates between 4kw to 250 kW (5 to 335hp), producing working pressure at 5 bar to 13 bar (72 to 188psi).
Our range of injected screw compressors are available with fixed or variable speed drives. The benefits of both depend on the unique demand of your business. Fixed speed compressors run continuously, regardless of demand and are very efficient when operating at 100% capacity. Variable speed compressors are able to increase or decrease the output according to demand, only using the required energy to provide the appropriate flow to produce compressed air.
When choosing a rotary air compressor you should always consider your operation demand. A variable speed drive can offer amazing energy efficiencies which translate into cost savings, however, if your application has a constant demand, a fixed speed compressor may offer you better results.
We know that the screw compression element is the heart of the compressor and therefore CompAir keeps the design and manufacture in-house, using the latest CNC rotor grinding machinery, coupled with online laser technology, to achieve fantastic results.
Furthermore, our premium airends have been specifically designed by expert engineers at the Simmern Centre of Excellence who are continuously endeavouring to improve compressor efficiency. Our specialists have optimised the design to ensure a low rotational speed, reducing energy costs and improving reliability.
Screw compressors are often used to supply vast amounts of compressed air to large industrial applications. The advanced technology allows the compressor to run continuously, providing a large output of high-quality air flow, perfect for demanding applications.
Typical types of applications:
Keep your screw air compressor running at peak performance with genuine spare parts, accessories and OEM compressor oil from CompAir's specialist Aftermarket business. We are dedicated to delivering products and services to maintain your compressor system with an extensive distributor network who can support you, around the clock.
The above airends in these oil lubricated air compressors can be driven by either a fixed or regulated speed (RS) motor, airflows range from 0.24 m²/min to 47 m²/min and power outputs from 2.2 kW to 250 kW. Regulated speed compressors can efficiently and reliably handle the varying air demands found in most plant air systems, achieving energy savings of up to 25%.
All models from 15 kW can be equipped with integrated heat recovery, to help recover the energy lost in heat.
