Areas of application
The KWF-inline single filter is a versatile implementation filter for liquid, gaseous or pasty media. It is characterized by high-performance, low spatial requirements as well a possibility for fast and easy cleaning. Inlet flange and outlet flange are equal height.
Brief description
In the standard version the filter consists of a welded steel vessel with cover that is fastened through screws and nuts. Alternatively the filter can be equipped with a strainer, ringer strainer insert or cartridges, or bag filters.
Installation
The filter is installed in pipelines via flanges. Ensure that the standard version of the filter is installed vertically, tension-free without additional mechanical stress. The medium must flow in the direction specified on the vessel. Incorrect installation can cause filter malfunctions.
