Below is a list of Pressure Filter manufacturers from Erie, Pennsylvania. Pressure filters are those filtration products that employ compressed air or pressurized fluid as the principle means of moving a process stream through filter media in order to separate materials and remove suspended debris. A pressure filter is not a specific filter design but rather a broad category of filtration equipment based upon the driving force of the mechanism. Alternative filtration systems use gravity, vacuum suction or centrifugal force to clean and purify gaseous or liquid materials in a number of industrial, commercial and even domestic environments.
