COMPRESSED AIR CompAir has announced its latest oil-free rotary screw compressors as part of its new D-Series range, delivering reliability, dynamic efficiency, lower operating costs, and high-quality oil-free compressed air. The range covers air and water-cooled models from 37 to 75 kW and is available in both fixed and regulated speeds (RS) delivering ISO 8573-1:2010 Class 0 certified 100% oil-free air for the most critical applications, e.g. within the food and beverage, pharmaceutical, textile, and electronics industries. No oil is used in the compression elements, neither for sealing or lubricating the rotors, nor for cooling the compression process directly, reducing the risk of costly downtime and contaminated products. For RS models, the combination of variable speed operation and hybrid permanent magnet (HPM) motor delivers ultra-efficient performance and lower energy costs. Offering best-in-class efficiency and 30% or more energy savings compared to conventional compressor control, the simple, virtually-maintenance free HPM motor has 60% fewer components than a standard induction version. It has no bearings, pulleys, gears, or motor shaft seals to wear out, leak or need replacing, meaning reduced service time and spend. The motor also requires less power at start-up (95% efficiency at start-up) compared to other VSD compressors and never operates unloaded thanks to an unlimited number of starts and stops. Enhanced reliability Enhanced reliability is claimed to be another key benefit of the new D-Series range compressors. Stainless steel components, dual-vented seals, and precision machined rotors with advanced Ultracoat prevent downstream contamination due to corrosion, while ensuring a trouble-free and long-lasting operation. The range also features a robust airend with precision machined gears, oversized bearings, stainless steel air seals, and unique labyrinth oil seal design to eliminate the risk of internal leaks. Meanwhile, an intuitive Xe system controller with integrated speed control, remote communications capability, and extensive events history, enables users and owners to optimise and improve compressor performance. The D-Series compressors feature iConn as standard. iConn is a smart, proactive real-time online monitoring service that allows operators to manage the performance of the system through invaluable data statistics and insights. www.compair.com/en-gb CompAir launches dynamic new compressors in D-Series range D37.
