Did you know
- Boll & Kirch has been manufacturing industrial filters for over 75 years. The 2.xx series of duplex filters includes models like the 2.04.5, 2.05.5, 2.06.5, 2.06.7, 2.59.5, 2.68.2, and 2.78.2.
- The 2.xx Series (Duplex Filter) sits within Boll & Kirch's range of filters as a type of duplex filter, designed for continuous operation. This contrasts with their simplex filters, which have a single filter housing, and their automatic backwash filters (6.xx and 8.xx series), which are self-cleaning and often used for continuous contamination or automated processes.
- The primary strength of the 2.xx Series Duplex Filter is its ability to ensure continuous operation without interruption. This is achieved through its dual-chamber design, allowing one filter to be cleaned or maintained while the other remains in service.
