COMPRESSED AIR 38 HYDRAULICS & PNEUMATICS April/May 2021 www.hpmag.co.uk CompAir has introduced new models to its L-Series range of oil- lubricated screw compressors. Covering 2.2kW to 7.5kW models, the new fixed speed units are claimed to be highly versatile. From a stand-alone compressor to a complete air station with a high-performance dryer and intelligent control system for low- pressure losses, the systems can help meet a range of individual customer requirements. CompAir comments that the user-friendly and compact design of the new CompAir L-Series range means they are easy to use and ready for plug-and-play operation. As a result, these solutions are ideally suited to smaller applications across the general engineering, automotive, and woodworking industrial sectors, which specifically require high-performing compressors to meet fluctuating air needs and ensure energy efficiency, ease of maintenance, and low noise operations. The compressor itself requires a minimum floor space of only 60 x 65 cm, with the receiver-mounted models being exceptionally space-saving. Low noise levels With noise levels as low as 63 dB(A), these latest models can be installed almost anywhere without major disturbances to the working environment. There is no need for a separate compressor room or expensive pipework, meaning installation costs are reduced. The simple design of the units also minimises the number of moving parts, improving reliability and scaling back maintenance costs. Compressor maintenance is made easy by the removable top and side doors, providing users with quick and easy access to all service points. The latest L-Series compressors feature a new C-Pro1.0+ controller as standard, too. Information about pressure, oil temperature and compressor status to the operator together in one display. The controller offers a host of other features too, including a communication port RS485 supporting Mobus. The controller can be used also as a sequencer between two machines with C-Pro 1.0+, continuously monitoring all the critical parameters of the compressor. In-house design and manufacture The screw compression element is at the heart of the CompAir launches latest L-Series models from 2.2kW to 7.5kW compressor. Therefore, CompAir keeps the design and manufacture in-house, using the latest CNC rotor grinding machinery, coupled with online laser technology. The resulting reliability and performance ensure that operating costs remain low throughout the compressor’s life. A highly efficient ITEFC E3 electric motor is also fitted as standard, reducing power consumption and C02 emissions. Dora Artemiadi, product manager at CompAir, says: “We are extremely excited to bring to market the latest models in our L- Series range. CompAir’s new oil-lubricated screw compressor solutions can be relied on to provide consistent, cost-effective, and high-quality compressed air and are capable of delivering pressure ranges up to 10 bar, and volume flow between 0.18 to 0.89m 3 /min. “These new models are offered with a range of options to suit a user’s unique requirements. For example, the Star Delta starter is included as standard from 4kW up to 7.5kW, while 5.5kW and 7.5 kW variants include an aftercooler to optimise air quality and minimise the size of downstream needed.” www.compair.com
