Duplex-Filter
Product Category: Welding Engineering
A duplex filter consists of two filter chambers. While one chamber is in operation, the other remains on standby. When the in-service chamber becomes fouled, the system can be switched to the standby one without causing abrupt pressure changes, allowing the fouled chamber to be manually cleaned without interrupting the system operation.
The switching of filter chambers is achieved through optimised valve body technology adopted from top international brands. The design of the changeover valve ensures that both filter chambers can never be closed simultaneously, thus guaranteeing operational safety.
