CompAir has announced its latest oil-lubricated compressors; the L-Series range covers air-cooled models from 55 to 75 kW and is available in both fixed and regulated speeds. When compared with previous models, the new compressors offer up to 8 per cent efficiency improvements, as well as up to 5 per cent higher flow rate.
The range incorporates many features that the previous models offered – such as an automatic motor lubrication system as standard to help reduce downtime and increase the lifespan of motor bearings, as well as a semi-integrated airend and Victaulic fittings for easy maintenance and reduced leakage risks – but encompasses a range of key new benefits, too.
One of these is the newly designed, semi-integrated airend. Featuring a new rotor profile that delivers outstanding performance while reducing noise and vibration levels, the airend is manufactured in-house, at the company’s Centre of Excellence in Simmern, Germany. It has also been designed with a larger-sized inlet and outlet. This helps to increase air flow and limit pressure drop, thereby providing owners and operators with best-in-class compressed air performance for this range.
For variable speed models, the new airend comes with an automatic oil regulation valve, which controls the oil’s discharge temperature according to environmental conditions. Not only does this remove the risk of condensate and – as a result – corrosion, but it also ensures the oil in the system remains at suitably high standard at all times and can improve efficiency levels by up to five per cent. This has been cleverly integrated, along with the oil filter, into the airend’s housing, helping to eliminate the risk of oil leaks while simplifying maintenance too.
In addition, the new airend is supported by CompAir’s Assure warranty, which covers the airend for up to ten years or for 44,000 hours.
Service and maintenance have been made easier: all doors on the unit are hinged and can be easily removed, improving accessibility for users while also assisting with space requirements. Furthermore, service parts, such as separators and filters, have also been optimised to ensure maintenance is an easy process. For instance, the systems’ new separator design not only provides an oil reservoir that helps reduce pressure drop but includes a hinged top plate and only one integrated seal, too. As a result, o-rings do not need to be removed and then fitted again during maintenance work.
Just like previous models, the new compressors feature the Delcos XL touchscreen controller, a user-friendly, intuitive and visual means of monitoring the operating parameters of the compressor. They also feature iConn as standard: a smart, proactive real-time monitoring service that allows operators to manage the performance of the system, through data statistics and insights.
An IE3 electric motor comes as standard with these systems. There is the option of upgrading to an ultra-efficient, energy-saving IE4 electric motor if required. The units are capable of delivering pressure ranges from 5 to 13 bar, and volume flow between 2.1 to 14.03 m3/min.
