Drip-proof filter plates (in gas-tight design (CGR)) are especially used when the filter chambers must be particularly tight during the filtration cycle. The filter plates are available with a variety of sealing materials such as EPDM, silicone, NBR and FKM depending on the durability requirements and individual customer requirements.
THE RIGHT SEALING MATERIAL IS CRUCIAL
For the food and pharmaceutical industry, FDA-certified or EU-compliant seals are used accordingly. Sealed filter plates are mainly used in direct filtration filter presses for dewatering phosphate sludge.
