Real technology introduces vacuum filters. The basic work of vacuum filter consists of filtering and recirculating process liquid, done in the following manner. Initially, the dirty liquid is drawn through filter media by the filter/distribution pump. Due to this, vacuum is created leading to automatic operation. Vacuum is eliminated by backflow of clean fluid into vacuum chamber and filter media progresses. The build-up of solid cake enhances filtration. The filter makes complete utilisation of the filter media. The benefits of this machine include low maintenance and less energy consumption, as it does not require a separate pump to supply machines. The filter generates suction vacuum at paper clog conditions.
