Single Stage

OEM Air Ends

The SP-Series single-stage air end has a capacity range of 100-3800 acfm. It can operate with a discharge air pressure as low as 50 psig or as high as 300 psig. The robust casting designs, along with high-capacity flanges, enable the machine to run at higher pressures and minimize inlet losses, all while reducing noise levels.

The air end is equipped with high-quality taper roller bearings and extra wide cylindrical roller bearings, ensuring a long duty cycle life even in extreme environments. Additionally, there are multiple seal options to choose from, catering to your specific application needs.
