Water traps are simple devices that filter both moisture and debris from the air that passes through them. As your compressor runs, condensation is created which then cools and collects in your air tank. Installing a water trap between the compressor and the tank will limit the amount of water that ends up in your air tank. Installing a water trap between the tank and the manifold / valves will collect any excess water that makes it through the tank, as well as any debris it picks up along the way, further protecting your investment. We offer a bunch of different styles and sizes so if you have any questions, feel free to contact a Bag Riders air ride specialist for more information!
