View Staff Answer 

The Viair Portable Extreme Series Compressor 450P Automatic 45043 is equipped with permanently lubricated, maintenance-free motor. You must regularly clean dust and dirt from compressor cooling fins and motor housing. Also, for optimal compressor performance, replace filter element periodically. Clogged filter will drastically reduce compressor flow rate and performance.

VIAIR Corporation warrants this product, when properly installed and under normal conditions of use, to be free from defects in workmanship and materials for a period of one year from its original date of purchase.

VIAIR offers an Industrial Grade (IG) compressors that 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 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.
