Battery-powered screw compressor

Atlas Copco has expanded its portable electric product portfolio to include an all-new battery driven portable screw air compressor, the B-Air 185-12. The B-Air 185-12 features 5-12 bar of pressure, a stable flow rate of 5.4-3.7 m³/min and 55-kWh battery storage capacity. With power delivered from its onboard power pack, in operation a fully charged unit is independent of the need for fuel or a local power source to plug into, and has the capability to perform for up to a full typical work shift. In turn, it provides both portability and productivity for those working on sites where regular access to electricity is not practical. Making the switch from an internal combustion engine (ICE) to electric motor brings with it a host of benefits, including less downtime and maintenance requirements. Due to having far fewer moving (and therefore wearing) parts compared to a diesel powered unit, the electric B-Air 185-12 only needs to be serviced every 2,000 hours, as opposed to 500 hours for a typical ICE powered unit. The machine’s state-of-the-art Variable Speed Drive (VSD) and permanent magnet motor drives down the total cost of ownership, automatically adjusting the motor speed to match air demand in real-time and increasing energy efficiency by up to 70%. Through Atlas Copco’s rigorous testing process, which includes rapid aging testing under harsh conditions and climactic chamber testing, the B-Air 185-12 has been proven to perform optimally even in the most extreme of climatic conditions – ranging from +45°C (+113°F) to a glacial -25°C (-13°F); and 4,500 metres (14,764 ft) above sea level. The unit is also designed to excel in densely populated urban areas where emission and noise pollution are tightly restricted, thanks to it producing no local emissions and having low noise levels. The quiet nature of the compressor enables operators to work without noise distraction, enhancing both productivity and safety.
