FVB type Rubber Duct Compensator
FVB type rubber duct compensator is a device used for flexible connection between fans and ducts, the main function of which is vibration damping, noise reduction, sealing and media resistance. It can effectively reduce and eliminate the noise and vibration transmission generated by boilers, fans and other systems, and guarantee the stable operation of equipment.
Overview
Features
Shock absorption: can effectively reduce and eliminate vibration.
Noise reduction: It has good sound absorption effect.
Sealing: Ensure the airtightness of the piping system and prevent the leakage of medium.
Resistant to medium: able to adapt to different working environments, corrosion resistant and high temperature resistant.
Convenient displacement and installation: flexible design, adapt to a variety of installation needs.
