Why a Compressor Check Valve Is Essential in Oil-Free Air Systems

On there is a very essential role of a compressor check valves in an oil free air system. This little nook of tissue helps ensure that air travels in the correct direction. As the compressor pushes air out the check valves opens allowing air to pass.  

How Is the Compressor Check Valve Important In Oil-Free Air Systems

Check valves are an integral part of oil-free air systems. Think of them as a one-way street for air. The one-way check valves will open when the air is pushed out by the compressor and will let it go where it has to. But when the compressor shuts down, the valves closes and stops any air from backing up. This is really important because if air starts going back, it can contaminate.  

Selecting The Perfect Compressor Check Valve For Your Needs

The proper compressor check valves can enhance the performance of your oil-free air system. First you should consider the size. The valves must be sized to the air pipes you plan to use. If it’s too short, it can’t open enough to allow a lot of air through. Too much seal, and it may not seal as well and air could escape back in. Next, consider the material. Metal valves are generally stronger, but plastic ones may be lighter and more resistant to corrosion. You should also consider pressure ratings.  

Why Do Oil-Free Air Systems Rely on Quality Check Valves

Oil free air systems are unique as it does not require oil to assist the air. That is to say, they are cleaner and better for the environment. In these systems, there is a compressor that pushes air into a tank. The air needs to remain in the tank until it is called for. And that’s exactly what a check valves does. A pressure safety valve is similar to a one way door. It lets air into the tank, and won’t allow it to escape. This is crucial because if air leaks back through, the system can become less efficient.
