EP Aeration has been using Gast 82R, 1/3rd horsepower, oil-less air compressors in our pond aeration systems since early 2013. Thus far they’ve proven to be robust and well suited for the application. Just like previous versions of this wobble-piston style compressor, it requires a rebuild every 2-3 years depending on operating conditions and air filter management. The following video demonstrates the simple procedure for rebuilding this compressor. Please contact us for troubleshooting questions, parts, or to locate a certified service technician.
