Features of Dry Screw Vacuum Pumps: Oil- and water-free, dry operation provides a clean vacuum environment No friction between the screw and housing ensures pump life New dry rotor design provides volumetric efficiency No oil or water required as a medium, low cost Single-stage design facilitates solid removal within the pump Short gas path within the pump allows for rapid gas discharge Special coating handles toxic, corrosive, and condensable gases Simple design for easy maintenance Low-speed operation, low vibration, and low noise Advantages of the FSP Series: Adopts a variable-pitch screw Power consumption is reduced by 30% compared to conventional designs, Significant savings in utility costs Lower operating temperatures, more compliant with T4 standards Improved vacuum volume increases vacuum levels Simple design saves installation space Mainly uses flange connections, simplifying installation and reducing noise Reduced coupling error
