Zero Leak / Gasketed / CGR (Caulked, Gasketed, and Recessed) Filter Plates are an advanced version of the traditional Recessed Chamber Closed configuration plates. These plates, designed for leak proof operations, have a filter cloth which is secure with caulk into a groove round about the recess plate. This design with special ‘O’ ring sealing system ensures that when the plate pack is closed it forms tight seal with no leakage making them ideal for handling toxic substances, acidic solution, s and other critical applications.
