The vacuum filter is a negative-pressured, gravity-assisted, filter media-based filtration system. It is an evolved form of the basic paper band filtration system with the advantage of occupying lesser floor space.
For processes removing finer materials such as grinding, rolling mills etc, a finer filtration level is required. If the fluid is not filtered to the desired filtration level, the particles may leave a mark on the surface. Normal gravity filters do not give the desired filtration level and the media consumption can be very high. In such cases, a vacuum filter is an ideal solution. With the help of a vacuum producer, finer filter media can also be used for very fine operations.
