FUNCTION

With the »Active Wall-Flow-electrics« (AWF-e) Particulate Filter System, we of­fer you a versatile particulate filter sys­tem for machinery and sys­tems that are operated regularly at a fixed location or within a limited deployment radius or for limited pe­ri­ods of time. These include lift­ing plat­­forms, municipal vehicles and in­dus­trial trucks, as well as stationary pow­er ge­ne­ra­tors.


The filtered particulate is regenerated us­ing a heating coil that is integrated into the system’s inlet hood upstream of the filter element. The sys­tem is connected to an external power supply at the end of a shift, after deployment for a limited pe­riod of time, or when the filter mo­ni­­tor­ing system shows a cor­res­pon­ding mes­sage on the display. Once the system is connected to the mains, the re­ge­ne­ra­tion process can be star­ted.
