Performance 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 Tables

The 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.
