Fixed and regulated speed rotary screw air compressors CompAir has launched a completely new range of high efficiency, oil-free two-stage rotary screw compressors to further enhance its successful and award winning D-Series. With the addition of 8 new models, these high output oil-free machines now cover a wide flow range from 5.1 to 51.8 m3/min. The D37 to D315 models are fixed speed and the D37RS to D315RS models are regulated speed.

CompAir has extended its Oil Free rotary screw compressor range with the new DS37-DS150 fixed and variable speed series. What it is: Class Zero Oil FREE Rotary Screw Compressor Nominal Power from 37-150 kW Capacity of up to 25.9 m³/min (@ 7 bar g) Complementing the established 160 to 315 kW model range Fixed Speed and Variable Speed (RS) Models Air-cooled Numerous Further Options

CompAir Ultima – U75-U160 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 90 – 132 kW range of lubricated screw compressors comprises of fixed speed and regulated speed (RS) models. Ingersoll Rand has unveiled its newest oil-lubricated compressors for its leading CompAir L-Series range, offering best-in-class efficiency. The compressors are equipped with a premium high efficiency electric motor, which can be upgraded to an ultra efficient energy saving IE4 electric motor. The RS (regulated speed) efficiently handles the varying air demand found in most plant air systems. The compressors incorporate quality components, such as high performance separator filter, large surface after cooler and thermostatically controlled motor driven fan. The design concept is not only based on energy efficiency but also on high availability and low maintenance costs. Therefore these packages ensure all service points are easily accessible. The reduced number of moving parts contributes to lower maintenance costs additionally. High reliability and high quality compressed air Comprehensive and user-friendly touch-screen compressor controller Superior energy efficiency High flexibility Small footprint Excellent accessibility contributing to the low maintenance costs Innovative oil regulation valve improves efficiency up to 5% (depending on model)

The 55 – 75 kW range of lubricated screw compressors comprises of fixed speed and regulated speed (RS) models. The new compressors deliver efficiency improvements of up to 8 per cent when compared with previous models, plus a 5 per cent higher flow rate. The new compressors are available in both fixed and regulated speeds – which can help reduce a system’s total cost of ownership significantly – as well as air-cooled and water-cooled options. Pressure range: 5 to 13 bar Volume flow: 2.1 to 14.03 m³/min Motor power: 55 to 75 kW

The new versatile screw compressor range from 30 to 45 kW can be configured to meet the customers’ efficiency requirements. The E-models feature a larger air end delivering highest efficiency levels. Well known in the industry for quality and reliability, CompAir continuously develops the L-Series achieving cutting edge performance and efficiency. The regulated speed models save energy by matching the output to the plant air demand. All fixed speed models are available with integrated dryer option. The E-Models of the L-Series screw compressors feature an extra large airend with optimised rotor tip speed achieving up to 6% energy savings. The largest cost component of a compressor is the energy to run it. The reduction of energy costs significantly impacts on the total costs of ownership. The additional investment costs for this range of super efficient compressors will pay back in many cases in less than 12 months. The extra large air end also has a longer life expectancy. Real Time Clock – allows pre-setting of compressor starting/stopping Second Pressure Setting Integrated Cooling and Dryer Control Fault History Log – for in-depth analysis Remote Control via Programmable Inputs Auto Restart after Power Failure Optional Base Load Sequencing SD Card – stores several run characteristics

A Scroll Compressor is also referred to as a Spiral Compressor, a scroll pump or a scroll vacuum pump. The Rotary Spiral Scroll design creates a continual compressed airflow over multiple stages and there is no need for oil lubrication. A scroll compressed air system runs quieter and more smoothly than a reciprocating version because there are only two moving parts – a fixed scroll and an orbital scroll. Fewer parts make the scroll compressor energy-efficient, highly reliable, and less prone to mechanical failure. Compared with a rotary screw compressor, a scroll compressor vibrates less and is almost noiseless. Scroll compression An orbiting (rotating) scroll and fixed scroll housing are mated to create the compression chambers. The continual movement of the orbiting scroll moves atmospheric air from the intake toward the center, compressing the air into progressively smaller areas. The compressed air is directed to the center discharge port of the compressor. Discharge pressure is accomplished during multiple stages of compression, resulting in a continuous intake suction and discharge. High reliability and high quality compressed air Easy operation and easy installation High flexibility Small footprint Energy efficient fully integrated airend design Low maintenance costs

Welcome to the new DX series range of oil-free air compressor from CompAir, with 8 new models available as both fixed and regulated speed versions in the large 200 - 355 kW range, pressure range: 4 to 10 bar, volume flow 11.4 to 53.4 m³/min When PureAir Technology is High Priority There’s a lot riding on the quality of your air. The presence of particles, condensate, oil and oil vapor in a compressed air system can lead to downtime, product spoilage and recall, damage to your brand reputation, or worse, harmed consumers and product liability.
