How to Combat Rising Humidity with Compressed Air Dryers

In some parts of the country, April showers bring May flowers and a heavy dose of humidity that tends to hang around well into the early days of fall. With temperatures and humidity on the rise, your compressed air system will experience additional water loading on the air treatment equipment. It’s important to note, at peak warm weather compressor operating conditions, there can be 650 percent more water in the air versus the highest temperatures in cold weather conditions.

The Impact of Humidity on Compressed Air Systems

In order for compressed air systems to perform properly the air must be dry. More specifically, the air must not contain liquid moisture and should be at a relative humidity of less than 50 percent to prevent corrosion. Bulk liquid in compressed air systems can block control air lines, damage air tools and cause water hammer events that damage equipment. Processes can also be directly impacted when water enters from the air stream.
