The unit illustrated on the top is the Model PEFHK8 (8” diameter screen) equipped with our Ultrasonic Deblinding Assembly. This system eliminates the blinding and blocking of wire mesh material. Eliminating mesh blinding allows for sieving of finer mesh down to five microns. Units are available in 8″ and 12″ diameters. This unique system also allows for retrofitting any screening system on the market.
