Vibration Isolator Clearance
Equipment isolators need room to move. If duct, curb, piping, or structure binds the equipment, the isolator cannot do its job.
What This Helps With
Equipment isolators need room to move. If duct, curb, piping, or structure binds the equipment, the isolator cannot do its job.
Apprentice words: vibration isolator clearance, fan vibration, flex connector, equipment isolation
Common problem: Duct connection or support locks equipment solid even though isolators were installed.
Check First
What Not To Do
Do not hard-connect duct so it bypasses the vibration isolation. Do not use ductwork to brace equipment unless detailed.
What can go wrong: Duct connection or support locks equipment solid even though isolators were installed.
Better Foreman Question
Is this duct connection allowing the isolator to move, or are we hard-locking the equipment?
Verify With
Source to verify: Equipment submittal, vibration isolation detail, project spec
Safe wording: Vibration isolation is design-specific and often coordinated with equipment manufacturer.
