The CFM 08 Series of industrial vacuum cleaners feature clog-resistant filters and interchangeable attachments for fast, continuous cleaning, and quiet-running motors and cord holders for easier, safer operation. The three-phase, HEPA-filtered CFM 08 Series vacuums – which include the CFM 3308, CFM 3508, CFM 3508W, and CFM 3558 – are engineered for non-stop operation and minimal maintenance, making them ideal for process-integrated applications, central systems, and general maintenance cleaning. Oversized main filters prevent premature clogging while collecting ultra-fine powders; a newly designed filter shaker handle enables workers to “shake down” filters with minimal effort; and a side inlet provides a better cyclonic effect, resulting in maximum suction power and minimal clogging.
