Function & Application of Spring Hangers & Neo Spring Hangers
The function of spring hangers is to absorb vibration & vibration related noise of Fans, Fan coil Units, Ducts & Pipes etc.
The vibration absorber by spring Hangers will be better if you use higher defection springs like 2". The efficiency goes over 90%.
Neo Spring hangers are still better & recommended by engineers because of additional Neoprene element at the top of the bracket which eliminates metal to metal contact.
Features of Spring Hangers/Neo Spring Hangers
Spring Hangers are large diameter steel springs housed in rectangular steel housings.
AHI Standard design allows angular hanger misalignment.
Many AHI Spring hangers are designed with rubber cup in place of metal cup in the bottom of the bracket which eliminates metal to metal contact& give better efficiency.
Springs are galvanised & not painted for better rust protection.
