Air Flue Compensator(FVB)

1:characteristics

Due to the flexibility of rubber and fabrics as well as sound absorption,vibration isolation,it can well reduce the noises and vibration transmission of blilers,fans and air flow in operation.For the main materials are rubber or finer fabrics and the fibers have features of temperature preservation and thermal insilation,no reserve thrust and light weight,it needs no pipe bearing sound high temperature resistance and corrosion resistance,for the rubber has higher air-tightness absolute no leakage,low costs,much lower than that of metal compensator and imported products
