Solimar Pneumatics, Minneapolis, MN is a leading designer and supplier of aerators to promote discharge of cement and fly ash from silos, dust collectors, bins, filters and trailers. The company’s aerators can be ordered on new equipment or retrofitted utilizing the company’s Fast-Fit or EZ-IN kits. The disk distributes air along the wall, freeing up product with air pressure and gentle vibration. The patented silicone disk seals against the wall preventing plugging, bridging, rat holing and compacting. Once installed, the aerators are maintenance-free and do not plug like cloth air pads that require replacement and confined space entry for maintenance. Controllers are available to group aerators and sequence them for better flow. The company provides free engineering assistance to advise the best placement and number of aerators necessary for maximum effectiveness.
