The Midland Haldex EL13040X is a 1300 Series air compressor designed for Cummins in-line engines. It delivers 13.0 CFM at 1250 RPM with a 2.75 in. bore and 1.50 in. stroke. The head is rotatable, and the unit features a double flange mount with gear drive and top/flange discharge. Oil feed is through the flange, with a side option available on service units. Both head and block rotate right (viewed from front). The EL13040X serves as a high-capacity replacement cross-reference to the EL16040, and is an exact replacement for OEM part number NT7004B. Overall dimensions are 12.38 in. tall, 5.68 in. wide, and 9.09 in. long, with an external shaft length of 0.54 in. The unit is water cooled and turbochargeable. Available from Pro Gear and Transmission, call us to confirm fitment for your application.
