Based on simple technology where a couple of five-lobe rotor rotates in the opposite direction and gas getting in to the pump absorption, it is used in diverse vacuum field. Connected to oil rotary vane pump, piston pump, and dry pump, it quickly approaches the reserved pressure in quick exhausting speed and short time. FRU series is pump designed in by-pass valve structure and the Roots pump that is combined with latter pump, helps reduce energy consumption, prevent motor damage, and gives no need for pressure switch as the pump operates simultaneously at the ambient pressure.
-Saved energy consumption by reduced operating time by inhaling from ambient pressure.
-Steady and excellent performance and applicable in all vacuum applications.
-The pump have two outlet port, vertical and horizontal, to enable convenient piping with backing pump
-ISO flange is used for inlet and outlet port
-Low vibration level, low noise level
-Easy maintenance and repairing
Systematic connection to oil rotary vane pump, piston pump, dry pump, enables quick approach to reserved pressure.
