Blowers are circled in Red on last picture are items for sale in said photo.Technical SpecificationsBased on the electrical and mechanical configurations for this model:Motor Power: 7.5 kW (10 Horsepower)Voltage: 200–220V (Standard for Japanese industrial equipment)Phase: 3-PhaseFrequency: 50/60 HzMotor Poles: 4 PoleOperating Speed: 1,440 – 1,740 RPMType: Rotary Positive Displacement (Twin Lobe or Triple Lobe)Country of Origin: JapanPerformance Data (Estimated)While exact CFM depends on the final pulley ratio and vacuum level, a 10 HP PD blower of this frame size (65mm port size class) typically delivers:Airflow Capacity: Approximately 120 – 160 CFM (at open flow).Vacuum Depth: Typically capable of 12" to 15" Hg (inches of Mercury).Port Size: Generally 2.5" to 3" (65mm) inlet and outlet.Key Application: CNC Vacuum TablesThe BS65 is a "high-vacuum, low-flow" style blower compared to regenerative blowers. It is specifically chosen for CNC router tables because:Constant Suction: Unlike centrifugal fans, a PD blower maintains high vacuum even when parts of the table are uncovered.Heat Dissipation: These units are designed for continuous duty but require a vacuum relief valve to prevent overheating if the table is completely sealed.
