When changing the separator element, it is also recommended to change the compressor oil, most commonly Rotair Plus if you haven't changed oil types. It is also recommended to change your oil filter and air filter element.
The separator filter removes oil from the airstream before the air is sent downstream. Changing the separator element on an annual basis will increase your energy efficiency by reducing the pressure drop across the oil tank. This separator prevents oil from getting into your downstream production equipment. This CP separator element should be changed annually or every 4,000 hours, whichever occurs first.
