CompAir launches D-Series compressor range06 January 2022

CompAir has announced its latest oil-free rotary screw compressors as part of its new D-Series range. The range covers air and water-cooled models from 37 to 75 kW and is available in both fixed and regulated speeds.

They deliver ISO 8573-1:2010 Class 0 certified 100% oil-free air for critical applications such as within the food and beverage, pharmaceutical, textile, and electronics industries. No oil is used in the compression elements, neither for sealing or lubricating the rotors, nor for cooling the compression process directly, reducing the risk of costly downtime and contaminated products.

CompAir states that its RS models’ combination of variable speed operation and hybrid permanent magnet motor delivers ultra-efficient performance and lower energy costs. The virtually-maintenance free HPM motor has 60% fewer components than a standard induction version. It has no bearings, pulleys, gears, or motor shaft seals to wear out, leak or need replacing, meaning reduced service time and spend. The motor also requires less power at start-up compared to other VSD compressors and never operates unloaded thanks to an unlimited number of starts and stops.

Furthermore, whereas air compressors are generally designed to operate in an environment where the temperature remains between 5°C and 40°C, the new D-Series range from CompAir is able to withstand up to 46°C maximum ambient temperatures.

The D-Series compressors feature iConn as standard, too; a smart, proactive real-time online monitoring service. A specially-designed service plan for the CompAir oil-free product range is also available to support an extended warranty of six years.

The compressors are capable of delivering pressure ranges from 7-10 bar and volume flow between 3-13 m3/min.

Another option is an energy recovery system for both fixed and variable speed units. This sees compressor operating heat, usually lost to the atmosphere, recovered and repurposed for applications such as hot water, heating, and industrial processes.
