Air End Rebuild Services in North and South Carolina

Keep your Equipment Running Smoothly

If you own a rotary screw air compressor and are faced with the high cost of purchasing a factory air end, you now have a better choice.

Air end rebuilds are an optimal way to prolong the lifespan of an air compressor. The air end is also the most expensive part of the machine, making a rebuild a more cost-effective means of repairing an air compressor than replacing the entire system. A new air end will last between 30,000 and 100,000 run hours, while a rebuild lasts about 30,000 to 50,000 hours.

While screw air ends are made with longevity in mind, sooner or later, even the most robust air end will require maintenance or repair. Often, this happens due to simple wear and tear. The most common problem with air ends is the rotors get worn down, requiring replacement or repair. With in-house machining capabilities, ESA is a leading air compressor system repair source.

Due to the complexity and significance of the air end, we recommend you leave the maintenance to a credible professional. That’s where Engineering Sales Associates can help. We have provided air end rebuilding solutions for our customers for over six decades.

What is an Air End?

The air end is the essential part of any screw air compressor and is where the actual compression of air occurs. Inside each air end, you’ll find male and female rotor parts that rotate in opposite directions. These rotors squeeze the air through by sheer external force.

Air ends generate steady and continuous airflow. And when properly built, they are durable and resistant, even in harsh environments. Because of their ruggedness, air ends are often used in construction, mining, firefighting, and other applications where the environment can be challenging.
