Powerex OTS0503 5hp Oil Free Reciprocating Compressor, 18.2cfm, 80 Gallon, Three Phase

The Powerex OTS0503 is a 5hp oil free piston air compressor that is rated to displace 18.1cfm @ 100psi. This compressor runs on either 208v 230v or 460v three phase power and is mounted on an 80 gallon horizontal air receiver. The Powerex simplex reciprocating piston tank mounted systems are perfect for any application where clean dry air is required. The self-lubricating composite piston technology – standard on all Powerex reciprocating compressors – increases ring life and reduces temperature providing reliability for years to come. The dual cooling pistons reduce operating temperatures and the corrosion resistant components and coatings extend ring and valve life. The OTS0503 series utilizes the OPt050 oil free compressor pump.

The Powerex OTS series compressors have been designed and tested to meet the most demanding specifications of the oil free industry. All motors used on these compressors are NEMA Class B or better. 

OTS0503 is available in 208v, 230v or 460v three phase power. A magnetic motor starter with overload protection is pre-installed prior to shipping and wired based on your buildings power. The 80 gallon receiver tank is ASME rated.

This compressor package is able to be configured in an array of different variants, including the potential to add either a refrigerated or desiccant dryer pre mounted and installed on the receiver tank.  Please contact our sales department to help tailor a compressor specific to your needs.
