Abstract: The disclosed apparatus comprises means for effectively removing excess moisture from compressed air such as employed, for example, in spray painting applications. The outlet line from an air compressor is connected to the inlet of hollow coil of metal with good heat conductivity, such as copper or aluminum, having an outlet connected to an air manifold. The coil and manifold are both immersed in chilled water, whereby the temperature of the air and its capacity to hold water vapor are significantly lowered to cause the water to be condensed in liquid form and collect at the bottom of the manifold.
