Doosan Designed Equals Increased Productivity

NEW OEM Manufactured Airends: Doosan Portal Power has a long staff history of developing and manufacturing high quality two stage high pressure airends. While part of Ingersoll Rand, Portable Power staff were responsible for manufacturing, supporting and remanufacturing airends used in portable compressors and IR Drills. That experience was leveraged when Doosan purchased the Portable business resulting in the HR350 airend.
Remanufactured (rebuilt) Airends: Doosan Factory remanufactured airends are carefully disassembled and inspected to ensure that any damaged or obsolete parts are replaced. Each airend is rebuilt by experienced craftsmen at Doosan Portable Power’s worldwide headquarters.
The Airend Exchange Program also offers extended Warranty Options, In fact all rebuilt airends get a new airend warranty which is eligible for an extended warranty.
