ALMiG Screw Compressors

ALMiG Gear Series


The ALMiG GEAR Series are the heavy lifters of the ALMiG line of screw compressors. The gear driven plants of this series allows for these compressors to meet the challenge of extensive air requirements while maintaining ALMiG's reputation of quality and durability. Its unique design allows for operation under any ambient condition. The ALMiG GEAR Series was designed for the sole purpose of guaranteed high performance under 100% load on a 24/7 basis. As always, efficiency is taken into account with the GEAR Series maintaining above 98% efficiency due to flexible gear drives with easily replaceable working elements that protect the drive. Overall, the GEAR Series lowers your investment cost and combines that with lower life cycle costs due to extended maintenance periods. If you're looking for power, reliability, and efficiency than the ALMiG GEAR Series is perfect for your application.
