The Miller 250892 Drive Belt is the genuine replacement part designed to get your machine back up and running with the reliability you expect from Miller Electric.

This 6-rib belt is built tough to handle the demands of the Air Pak's engine, driving the compressor and generator components efficiently. If you have noticed squealing noises, a drop in air pressure, or if your maintenance schedule indicates it's time for a change, this is the correct part for the job. Preventive maintenance is key to avoiding emergency repairs in the field. Keeping a spare 250892 belt on hand or in your maintenance truck is a smart move for any professional welder relying on the Air Pak system.
