The stainless steel VF-100 powdered activated carbon feeder from Eagle Microsystems uses a direct drive for harsh chemical feed environments. It can be optimized for any PAC application with options including dust collectors, flex-wall agitation, explosion-proof motors, wetting cones, solution tanks, flow-pacing control, extension hoppers and multiple screw and motor ranges to accommodate any feed rate. The feed rate is regulated by an electronic silicon-controlled rectifier speed control. 610/323-2250; www.eaglemicrosystems.com.
