New CompAir FourCore range balances two-stage efficiency with single-stage footprint29 September 2021

CompAir has announced the launch of its new 160, 200 and 250kW FourCore compressor range, combining what it calls best-in-class compressed air efficiency with a small footprint and sustainable design, particularly for large energy users, such as those in the manufacturing and automotive sectors.

The FourCore range is said to offer all the capabilities of a two-stage compressor, but with only the footprint of a single-stage unit. It therefore provides businesses – who might not have previously had the on-site space available – the opportunity to take advantage of the capabilities of two-stage technology. Also, when compared with previous single-stage compressors in this size range from CompAir, the new models are up to 8% more efficient, offering a best-in-class oil-lubricated solution for decision makers.

At the heart of these latest models is CompAir’s new GD10-DS airend, which is where the range takes its ‘FourCore’ name from. This compact, two-stage airend uses four gears rather than three, to deliver flexible rotor speed adjustment at both low and high pressures. The new GD10-DS airend is semi-integrated, with the oil filter, check and temperature valves, and distribution system all integrated into the airend’s package. This results in less connections and pipework, minimising the likelihood of leaks and enabling easier servicing, saysCompAir.

In terms of reduced carbon emissions, when compared with a traditional compressor the new 160kW model, running for 8,000 hours a year, can reduce the equivalent greenhouse gas emissions of 32 passenger cars over the course of one year.

The environmental credentials of the range is impressive too. When compared with a conventional two-stage compressor, the new 200 kW model uses 22% less materials and can help cut waste by up to 19%.

To help deliver further energy efficiencies, integrated heat recovery is offered as an option on the new range. By recycling the heat generated from a compressor, which would otherwise be lost to the atmosphere, businesses can re-purpose this energy to heat water, for space heating, or for application processes in other areas of the installation.

The compressors are available in both air-cooled and water-cooled models, as well as variable speed and fixed speed options.
