Industrial Grade (IG) compressors feature an innovative patents pending head design for better heat dissipation and are specifically designed to fill reservoir tanks. All IG compressors are certified CE spec. and feature outstanding sealing properties against the elements. Additionally, all IG compressors are equipped with a separate stainless steel braided PTFE-lined leader hose and check valve assembly that protects the compressor against high amperage restarts.
