Ingersoll Rand has launched two new portable compressors – the 7/26E and 7/31E – which will replace its existing 7/26 and 7/31 models.

The new compressor models, which are based on a redesigned common platform, will offer several important features and options not previously available for these models. Other developments include an increased run time due to the use of a new 50-litre fuel tank.
Demonstrating Ingersoll Rand’s commitment to protecting the environment, the company has included an important new option – the ‘bunded base’. Other options, such as the generator, aftercooler, overspeed valve, spark arrestor and twin toolbox that were only available previously on the 7/31, are now available on both the new compressor models. In addition, customers can choose an optional control panel providing comprehensive information with additional fault signals. A new lower cost version of the 7/31E without brakes (<750 kg) is also available, says a company spokesman.
He continues: “Designed to meet the 2006 noise regulations, the new 7/26E and 7/31E portable compressors both utilise a ‘service-less’ direct-driven 85 mm airend (the 7/26 used a belt-driven airend). The new compressors offer improved serviceability, thanks to a new lower canopy and single hinged upper canopy design.
“For environmental safety, the new bunded base option provides a fully contained base to ensure that all operating fluids (fuel, oil and water) stay within the compressor.
“The 7/26E and 7/31E portable compressors provide free air deliveries of 2.5 and 3.0 cu m/min at output pressures of 7 bar, respectively. They are aimed at a wide range of applications in plant hire, construction and general industry. This covers a number of standard pressure applications including powering breakers and tools in road repair, demolition and refurbishment.
“The generator versions of the 7/26E and 7/31E portable compressors meet a specific requirement in utility work for compressors that provide both electrical power for lights, tools and fusion welding and compressed air for powering breakers and other pneumatic equipment.
“Portable compressors are among the 57 types of outdoor equipment for which noise limits and labelling requirements have been set by European Directive 2000/14/EC. With a view to progressively reducing the noise limits, the directive has been introduced in two phases. The first stage became mandatory in January 2002 and the second came into force in January this year (2006). In compliance with this second stage, the sound power level in both the new 7/26E and 7/31E portable compressors is now 98 dB (A), says the spokesman.
