The Foot Upper Automatic (FUA) model sealer differs from our regular sealers by placing the sealing element on the upper jaw and the silicon rubber on the lower jaw. This makes it possible to protect the element from moisture and contamination creating a clean and secure seal. The FUA is designed for the continuous sealing of thermoplastic films such as polyethylene and polypropylene. The sealing time in these units is controlled by a plug-in transistorized circuit board and electronic timers. The uniform pressure provided by an electromagnet pulls down the sealing arm, helping eliminate operator error. Once the correct control settings have been programmed, consistent seals are maintained automatically and consistently, making the last seal as perfect as the first. The AIE FUA model sealers are ideal for packaging candies, foods, stationery, drugs, tools, replacement parts and a variety of other products. This machine includes an electric foot pedal for manual operation. When programmed, consistent seals are maintained automatically, making the last seal as perfect as the first. Controlled by electronic timers for heat, congealing and recycling make it impossible for operator error once set.American International Electric Warranty
