Sheet metal and HVAC contractors who produce round duct, elbows, and fittings in house recognize Spiro, the Swiss builder of spiral duct and fitting machinery. The Equipment Hub buys and sells used Spiro HVAC duct machines, including gorelocker elbow machines. We acquire duct equipment from mechanical contractors, sheet metal shops, and plant sales, inspect it, and ship nationwide. Inventory changes as machines sell and new ones arrive. If the Spiro machine you need is not listed, we will look for it. Browse HVAC machines and metalworking equipment, or sell us yours.
