C MODEL COMPRESSORS - 12 & 24-Volt (Use with Reservoir Tank)
VIAIR “C” model compressors are intended to fill air tanks. They are not equipped with an ON/OFF switch or pressure sensitive shutoff device of any kind. The use of a pressure switch and relay are recommended and required. All “C” model VIAIR compressors (except certain 90 & 100 series units) are equipped with a stainless steel braided leader hose and a check valve to keep the compressor from restarting under pressure which can create an amp draw spike and can cause motor damage. Most VIAIR compressors are equipped with a thermal overload protector that will shut down the unit when overheated. When cool, the compressor will automatically restart as normal.

INDUSTRIAL GRADE COMPRESSORS (IG) - 12 & 24-Volt (Use with Reservoir Tank)
Industrial Grade (IG) compressors are specifically designed to fill air reservoir tanks and feature a specialized head assembly that includes a newly-developed, patents pending intercooler for higher heat dissipation. All IG compressors are certified CE spec. and feature outstanding sealing properties to the elements. Additionally, all IG compressors are equipped with stainless steel braided PTFE-lined leader hoses and a separate check valve assembly that serves to protect the compressor by eliminating the possibility of high amperage restarts. IG compressors require the use of a pressure switch that allows operation up to each compressor’s maximum working pressure as well as a relay for installation.
