Vacuum filters form negative pressure at the filtrate outlet as the driving force of filtration.This filter can be divided into intermittent operation and continuous operation.Intermittently operated vacuum filters can filter suspensions of various concentrations. Continuously operated vacuum filters are suitable for filtering thick suspensions containing more solid particles. It is mainly used for vacuum filtration in chemical, pharmaceutical, petroleum and other industries. It has the advantages of light weight, convenient installation and maintenance, simple operation and so on.Vacuum filters include vacuum negative pressure filters. There are two types of vacuum negative pressure filters. The first type USES porous glass as the supporting pad of the filter membrane to ensure that the trapped particles are evenly distributed on the surface of the filter membrane, so it is particularly suitable for the collection and counting of particles.Another stainless steel screen with PTFE coating is used as the supporting pad for the filter film, suitable for collecting the filter liquid, such as sample removal and particle removal.This type of filter is also recommended for easier cleaning when filtering more viscous liquids, such as when collecting particles from oil samples. As long as using the reasonable design and the correct operation method, strictly control the quality, can prevent the vacuum filter from freezing phenomenon.• Cylinder diameter: 4. 6. 8 • Bracket can be attached • Quick change connector type, convenient and fast configuration • Quick installation and removal structure makes it easy to remove the filter element • Straight through type, inlet and outlet are in the same straight line, easy to install
