This 8-to-16 head fiberglass and plastic construction time gravity filling machine is designed to provide the ultimate level of corrosion protection and performance. This automatic filler is best suited for very thin liquids whose viscosity does not change with ambient temperature or with batch variation,such as detergent,toilet cleaner,bleacher,etc. Ideally suited for applications where recirculation of the product is not possible or desired. The fiberglass and UHMW plastic construction is impervious to bleach or strong acids. The sophisticated bottle management and error controls allow sustained high speed operation.
