Welcome to Allair, a division of Hartman Brothers Inc.. We are a family owned and operated business that has been around for over 100 years! Today, Allair is the largest independent provider of industrial gases and welding supplies in the Uncompahgre Valley and surrounding areas. We serve customers in the Montrose, Gunnison, San Miguel, Delta, Ouray, Mesa counties. Not only do we carry state-of-the-art welding supplies and equipment, we produce and supply many industrial, medical and specialty gases to hundreds of businesses and customers over Western Colorado. 
When you call Allair, you won’t get an automated menu selection on the phone; you’ll deal with real people, friendly and familiar employees. That’s because we’ve always prided ourselves on having long-term employees with little turnover. As a matter of fact, we know almost all of our customers by their first names – another Allair tradition.
