About Filter System Technik
Filter System Technik GmbH & Co. KG is a specialist company for industrial filter and extraction systems operating nationwide, headquartered in Witten. Its core activities are mechanical and electrostatic air filtration as well as oil filtration. The range of services includes maintenance, cleaning, overhaul and repair of filter systems, the sales of new and fully overhauled systems including design of volumetric flow and filter capacity, as well as installation, relocation and conversion including pipework. Custom-made products such as machine frames, expansion chambers and adapters made of steel are manufactured in the company's own metalworking shop, which — after sandblasting in-house — are coated with customer-specific coating systems. In addition, the company offers EloWatch, a patent-protected WLAN-based IoT filter monitoring solution for retrofitting, independent of manufacturer. Customers include companies from the construction machinery, mechanical engineering, pump manufacturing, large gearbox manufacturing, automotive supply and engine manufacturing industries.
