There are several different types of duplex bag filter housings. One type is single bag in a single housing, which means the flow through the filter must stop once the bag reaches its maximum dirt-holding capacity. Another type of duplex bag filtering system uses two side-by-side bags that are cleaned offline after each use. The bags can be removed by hand and the solids are usually recyclable, although this is not common.
The housing has two valves at the bottom and top. The influent valve should be locked into place if using butterfly valves. The sample port valve should be partially opened to allow the housing to degas before operation. The hissing sound produced by the water flowing out of the housing should be stopped immediately. If the bag was already in the filter, it will be filled with liquid and the valve should be closed. The housing is now ready for use.
DUOLINE duplex bag filter housings have no metal components and are ideal for applications where process flow cannot be interrupted. They divert flow using ball valves or butterfly valves, which are linked together and can be operated by push buttons. They can also be equipped with push-button automation for added convenience. These units are available with either an "U" stamp or ASME certification. You should select the right one for your application.
If the process flow is not required to be interrupted, then DUOLINE duplex bag filter housings are the perfect choice. They use butterfly valves to divert flow in a way that avoids interruptions in the process. Aside from these advantages, they are also available in a single bag filter housing or a multi-bag housing. And, they are easy to install. Aside from the versatility and ease of installation, you can also find a unit that is "U" stamped or ASME certified.
DUOLINE duplex bag filter housings have a top-entry and a side-entry design. The unique design consists of two separate vessels that are connected by a common linkage. This means the flow of water will never be interrupted, which is advantageous for many processes. Moreover, the filtration surfaces are more than doubled, which makes the unit a good choice for continuous or intermittent flow.
DUOLINE duplex bag filter housings are designed for applications where the flow can't be interrupted. They feature two separate bag filter vessels, which double the flow rate and filtration surface. In addition to this, they can also have a push-button diversion mechanism. The advantage of the duplexed design is its flexibility. This design is ideal for larger-scale operations, where large-scale filtration is required.
