Current model Availability checked 17 Sep 2026The GA 22 is the plain, fixed-speed GA model in this size class. Include any additional suffix when comparing another machine: GA+, VSD, VSD+ and VSDs identify different offerings.
For steady demand, compare delivered airflow and loaded input power at the working pressure. In a system with long quiet periods, also account for unloading and stopping behaviour; motor size alone does not describe running cost.
