We receive numerous requests for used along with new Tronair part numbers on HPUs and their respective identification. Tronair recently changed their part numbers on all their HPUs to a new numbering system. The old part numbers on their hydraulic power units are very similar but not quite the same as their new numbering system.
We have included a chart below on their previous numbering system along with the new chart for your comparison. If you have any questions on the part numbers or an older Tronair HPU, please let us know.
