Compressor Remanufacturing & Parts

FirstPower Group LLC has been maintaining and repairing OCB, ATB and SF6 high voltage circuit breaker compressors since 1979. Our years of experience have enabled us to observe, first-hand the common causes of compressor failure, including poor design and inferior materials, leading us to create affordable, effective solutions to common equipment problems.

Our full service shop can handle nearly any circuit breaker compressor maintenance, repair or modification request.

Low-pressure and Mid-range compressors are tested prior to disassembly. Once testing is complete, the entire unit is disassembled. Interior of core and all parts are inspected for wear or failure.
Housing is cleaned and maintenance parts, including bearings, seals gaskets and if damaged or worn, connecting rods are installed. New gaskets and seals are installed and the compressor is reassembled.
Each unit is test run for a minimum of 10-hours and tested for heating, blowby and pump-up times.
The compressor is then repainted & returned to active service.
