Becker 3ph variable speed vacuum unit. U5 Becker U 5 series units (especially with VARIAIR) are widely used in:
• Vacuum packaging and food processing (including MAP — modified atmosphere packaging).
• CNC router hold-down tables (though oil-lubricated versions are less common there than dry ones).
• Industrial material handling, printing, woodworking, or central vacuum systems.
• Medical or laboratory vacuum where reliable deep vacuum is needed.
• General process vacuum.
The VARIAIR controller makes it more efficient than fixed-speed pumps by adjusting RPM to match demand, reducing energy use and wear.
