Rotary Screw Compressor Air End Overhaul

Air Powered Services can fully overhaul your rotary screw compressor airend in our equipped workshop by our fully trained technicians using the latest technology and tools.

The rotary screw airend is the heart of your compressor. If the bearings are not changed within the recommended period, total bearing failure can occur causing damage to the airend. In most cases, the compressor is then written off as this is a costly procedure to fix.

Typical oil lubricated screw compressor bearing life is the 20,000-40,000 hour range.

Typical oil free screw compressors bearing life is up to 80,000 hours.
