The ELGi AB Series oil free rotary screw air compressor is designed to deliver 100% oil free air free of microbiological contaminants. The AB series is in compliance with ISO 8573-1 Class 0 and ISO 8573-7.

The AB Series is engineered to deliver maximum uptime and reliability, bridging the gap between energy efficiency and a low cost of ownership. The rotor design reduces pressure loss and increases stage efficiency. The rotors ensure energy efficient compressed air supply for demanding applications.

The AB Series utilizes a unique Water separation by Impact and Centrifugal Action (WSBIC) process which enables efficient separation of air and water with minimum pressure drop. 

The cooling system features fans and a larger cooling surface area that enhances the cooling of hot air. The integrated fan-motor assembly maintains low temperature thereby increasing life of the motor.
