All compressed air filters require servicing of the elements. Proper maintenance is important in order to keep the Extractor/Dryer performing at optimum levels. La-Man has taken great efforts to create a filter that makes servicing user friendly. By simply removing one bolt, the Extractor/Dryer never has to be disconnected from the airline in order to replace the elements.
On average, we recommend servicing the Extractor/Dryer every 6 months. Each model has a complete Service Kit available (see specifications for service kit numbers) that provides everything needed for proper servicing. Service Kits include a 1st stage replacement element, 2nd stage replacement element, cap gaskets, base gasket, and base core (honeycomb).
