ANVER JBS Single-Stage Safety Vacuum Pumps, Dual Inlet

JBS check valves hold the vacuum until a compressed air signal reaches the blow-off port. Use it for hold-down of non-porous parts.

Vacuum Pumps and Vacuum Generators

Single-Stage “Safety” Vacuum Pumps with Dual Inlet Ports
JBS Series

JBS vacuum pump

Note: JBS shown with optional vacuum gauge

The JBS Series vacuum generating system provides dual inlet ports for air supply and blow-off. Once a vacuum is obtained, the check valves hold the vacuum until the system is opened by a compressed air signal to the blow-off port.

Use this system for hold-down applications. Check valves are only effective on non-porous applications in a leak-free system.
