SEA Global Electromechanical Works offer old and new facilities are growing and frequently require more compressor capacity. There are opportunities to satisfy the demands for compressed air by with existing or used rotating screw compressors. While buying a brand new compressor may have advantages however, don't overlook the old equipment as "not worthy of the effort to repair." Because most rotary screw compressors utilize an oil seal to protect the airend (the part that houses the chambers for compression) which means that there is very little wear is seen in the compressor's. This absence of internal wear is the reason that often, the compressor is able to be repaired to its original condition at less than the price of purchasing a new one.
