Using an air compressor on a daily basis results in the buildup of moisture. Air compression creates collides hot and cold air within the system, causing water to condense, building up moisture inside the air compressor as a result. Any moisture within an air compressor system requires close and immediate attention.
Moisture buildup may be normal but it is not desirable. For example, water sitting on compressor parts can cause rust and create poor performance. Compressor parts can easily be harmed by carried moisture, such as freezing water on outside lines prohibiting their use.
Moisture buildup can also be harmful to the environment and to people who work around the compressor. Mildew and mold can form in any compressor, and both can cause illness. Bacteria gathering in standing water are usually more harmful than mold. Due to these possible complications, anyone who owns an air compressor needs to have a protocol or piece of equipment for dealing with water inside their compressor.
Larger systems can be equipped with air dryers that help control the moisture problem. There are several different types of air dryers for compressors; including refrigerated, desiccant, and deliquescent. All types are effective at preventing moisture build-up inside air lines, and your choice of air dryer should be determined by several factors, including the type of air compressor being used, the temperature of the ambient air, and the operating pressure of the compressor.
In addition to air dryers, air compressor owners can also use filters known as moisture separators to protect their compressor systems. Moisture separators are relatively inexpensive, considering how many costly repairs they avoid. They are easy to install and maintain, although they must be regularly drained due to the moisture they accumulate.
A good way to prevent moisture damage to your compressor and your product is through taking precautionary steps to reduce moisture. This can be done through draining your air compressor’s receiver often or adding a larger receiver, which will cool air passively. In an environment in which the temperature is controlled, your air compressor system will be less susceptible to moisture accumulation. Proper preparation and planning, along with routine replacement of filters, will also help control moisture levels. Following these suggestions can help you avoid most of the problems caused by moisture.
