Noise: 95 ~ 100dB (A) 

 Air flow: 5000m3 / h 

 After treatment effects: 

 The overall amount of noise reduction: 30dB (A) 

 Resistance: 50Pa 

 Fully meet the emission standards. 

 ZK - II fan ventilation silencers is our technical department developed its own design, composite impedance ventilation silencers. The noise reduction effect is good, low resistance, suitable for high pressure centrifugal fans, ventilation noise; I also design for the development of high-pressure centrifugal fan of ZK-type I ventilating muffler and air intake silencer. Working conditions on site according to the design, production of ventilation silencers, and customized to create the most appropriate noise reduction effect.
