Air Compressor Tubing

CDX Series

    • System Flow Controllers

      Stop wasting air.

      If your plant requires 90 psi of compressed air, why supply 150 psi? The CDX Series from CompAir is a balanced flow controller which provides an economical and reliable single point of control when it comes to controlling the air pressure delivered to your operation.

    Where Does Compressed Air Go?

    System Flow Controllers - CDX SeriesPie Chart

    CDX Savings Example – The 10/7 Equation

    Due to the leaks and waste found in every compressed air system, reducing plant pressure by 10 psi results in a 7% energy reduction. Installing a CDX Controller, along with adequate compressed air storage, allows compressed air to be stored at a higher pressure while delivering consistent, low-pressure air to your application.

    A 15 HP compressor running 3,000 hours per year at $0.10 per kW = $3,300 annual power consumption.
