NILFISK INDUSTRIAL VACUUMS introduced the Attix 33 and 44 wet/dry vacuums, featuring a redesigned filter cleaning system.

Its InfiniClean automatic filtration technology features a reversed air pulse, activated every 15 seconds, to keep airflow at a high level while a double-valve system minimizes performance drops during the cleaning cycle. Both models feature three-stage filtration. For more, visit www.nilfiskvacuum.com.
