Customers now have a choice of color for the mini-fluidizer that prevents bridging, rat-holing and compacting in silos, bins, hoppers and pipes. The white silicone disk is preferred by processors handling food grade products while the current blue disk is generally chosen for industrial applications. The advantage of the 2-inch diameter fluidizer is the ability to position it in tight curvature chambers with diameters as small as four-inches. The compact size provides material handling engineers and designers with more pneumatic conveying options. The disk aerators will withstand temperatures to 350 degrees F. The aerators are compatible with food grade materials and are FDA approved. The silicone material, which is used on the disk, will not tear or absorb moisture. Patent application on the new product is pending.
