Model CS 1435 H HEPA vacuum for dust extraction automatically cleans its filters without interrupting suction when it detects decreased airflow, saving time on the jobsite. The vacuum’s electromagnetic pulse cleaning system maintains maximum suction by automatically shaking the HEPA filters to remove debris during operation. Ideal in the workshop or on the construction site, it removes dust directly from power tools during drilling, sanding, grinding, or sawing. CS Unitec Inc. www.csunitec.com
