Our History

A Little History…

Sly was founded in 1874 as a manufacturer of foundry equipment. The company’s experience with dusty environments lead to its development of dust collection equipment. Sly holds the very first patent for a cloth-type dust collector issued in 1902.

The company has subsequently expanded into three styles of dust collectors:

cartridge
envelope
tubular bag

and three styles of wet scrubbers

Impingement baffle plate
Venturi
Eductor
