Powerex OTS1101 1hp Oil Free Reciprocating Air Compressor, 3cfm, 30 Gallon, 115v-230v Single Phase

The Powerex OTS1101 is a 1hp oil free piston air compressor that is rated to displace 3cfm @ 100psi. This compressor can run on either 115v or 230v single phase power and is mounted on a 30 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 OTS110 series utilizes the OPS010 oil free compressor pump.

The Powerex OTS serues 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. And the single phase 1hp motor uses a built in overload protection and a DPST disconnect switch.

OTS1101 is available in either 115v or 230v single phase power. A magnetic motor starter with overload protection is pre-installed prior to shipping and wired based on your buildings power. The 30 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.
