Filtration phase

While one filter unit of the Duplex filter is in operation for liquid filtration, the other filter chamber is always cleaned in reserve. If the tolerance limit of the clogging indicator is set, it indicates the pressure loss based on the degree of clogging. The tolerance limit can be specified in advance according to the requirements. 

Switching over the Duplex filter

The clean filter chamber of the liquid filter in reserve is put into operation by pressing the switchover button. At the same time, the filter chamber that was previously in operation is taken out of operation. The switchover to the cleaned filter unit takes place without pressure surges.

Cleaning phase

Duplex filters are easy to maintain. Before you start the cleaning process, the dirty filter chamber must be depressurized and the housing cover removed. The filter element can then be easily removed, rinsed with a cleaning fluid and thoroughly cleaned of dirt using compressed air or the optionally available ultrasonic cleaning device.

BOLL Duplex filters offer several advantages tailored to ensure uninterrupted operation and enhanced safety in industrial processes:

Continuous Operation Assurance: With BOLLFILTER Duplex filters, your process can keep running seamlessly. The duplex design allows for continuous filtration even during maintenance or cleaning procedures. By switching between filter elements, one side remains operational while the other undergoes maintenance.

Variety of Filter Elements: BOLLFILTER Duplex filters offer a wide range of filter elements and meet the most diverse filtration requirements. Whether your process requires fine or coarse filtration or special media for specific contaminants, BOLLFILTERs offer various options to optimize the efficiency and performance of the filtration solution.

Increased Safety: BOLLFILTER Duplex filters incorporate Double Block and Bleed (DBB) technology, enhancing safety during maintenance or element changeouts. DBB ensures that both inlet and outlet ports are sealed off simultaneously, isolating the filter chamber from the process flow. This feature prevents fluid bypass and minimizes the risk of contamination or leaks, enhancing operational safety.
