The Powerex OPT150 is a two stage bare oil-free compressor pump meant to be used with a 15hp drive motor. This is a three cylinder pump with two low pressure pistons and one high pressure piston. Powerex utilizes cutting-edge compressor technology to provide the most advanced and reliable oilless reciprocating compressor in the industry. The OPT150 is a two stage compressor meant to operate at 120psi, but does have a maximum pressure setting of 145psi. This air compressor is continuously lubricated by the sealed bearings to provide oil-free compressed air and long compressor life. No lubricant is required to be changed or topped off as this is oil free.
The finned flywheel creates a fan to blow air across the pump, resulting in lower operating temperatures for an increased life. There is a separate cooling fan that is attached to the front of the pump that further increases the cooling air.
The OPT150 includes an inlet air filter as standard. This assures that 99% of all dust particulates and debris are taken out of the system down to 10micron. The pistons are made of a high strength self lubricating composite using the most advanced technology. These heat reducing pistons eliminate the effect of excessive grease leakage at the wrist pin bearing. PTFE rings reduce wear and provide self lubrication. Piston rings should be replaced every 10,000 hours of operation. The wrist pin bearings of the OPT oilless compressors are needle bearings protected by two outer lip seals. The wrist pin bearing lip seals prevent the lubricating grease from leaking from the bearing area.
