To reduce vibrations transmitted along outgoing pipes or ducts by vibratory sources such as pumps and fans, these need to be suspended using anti-vibration hangers.
The extreme simplicity of the MOHANG anti-vibration hook also allows the removal of low-frequency vibration components, thus eliminating dangerous noise transmission routes that could compromise the isolation of the primary vibration source (the pump or fan) through other anti-vibration mounts installed at its base.
