Remanufactured Gas Bare Shaft Compressor Process

These instructions are an overview of how the process works when a bare shaft compressor is in need of being remanufactured. This is to help clear any questions that may arise prior to contacting customer service.

The process begins by contacting Vilter’s Customer Service Department. Vilter contact information can be found on page ii.

•Request a “VSG Single Screw Compressor Rebuild Form”.

•Submit the Rebuild Form and a Purchase Order (PO) for the inspection. A fee is required for the ini- tial inspection and teardown report; contact Vilter Customer Service representative for the latest fee.

•A Return Material Authorization (RMA) number will be provided.

•Send the compressor to Vilter in the condition as stated on the Rebuild Form (i.e. no oil in the compres- sor). Charges may apply if conditions are not met.

•A report will be sent to you after the inspection has been completed explaining what level of rebuild is necessary along with the cost.

NOTE

Level 3 - Current Reman Compressor requires complete rebuilding and re-conditioning to “as-new” condition. All the components listed in Level 2 are replaced plus all hardware, slide assemblies, pistons, and a main rotor (if damaged) and/or gate rotor supports.

NOTE

A Level 1 and Level 2 rebuild will include washing the housing and repainting over the current paint. A Level 3 rebuild will include blasting all the current paint off before repainting.
