A rotary screw air-end or element has twin rotors, which include male and female parts rotating in opposite directions. Air fills the space between the rotors and, as they rotate, the volume between them and the surrounding housing decreases, squeezing or compressing the air into a smaller space. Our factory-trained technicians and experienced in-house staff handle rotary screw compressor repair and services you can count on. We’ve worked in rotary screw compressor repair for decades so you can depend on H&K Pump for cost-effectiveness, worry-free operation, and limited downtime. We’ll do our best to fix the problem, but if that’s impossible, we are certified to sell parts from all major manufacturers. We have the right part when you need it, and we can help install and maintain it.
