Our History

Since 1874

With Sly’s focus on industrial dust collection, the company subsequently expanded into four styles of dust collectors and four styles of wet scrubbers.

- Envelope bag type: our Dynaclone and Pactecon legacy brands
- TubeJet tubular bag style baghouses: Top load, side load, square, rectangular, and cylindrical
- Pleated bag TubeJets
