The series silencer is specifically designed for the fan supporting the silencer, and the silencer using double wall structure, and to solve the high noise axial flow fan outlet of the problem, thus ensuring a good environment for the user. Fully considered in the design of fan performance, optimizing the internal structure of the silencer to minimize the loss of resistance, the manufacturing process on account of the user environment of the scene, the use of anti-corrosion measures.
Used in coal mines, tunnels, underground local fan for negative pressure ventilation.
1, blocking dust on the fan inlet muffler drag coefficient of about 2%, a weak influence on the fan performance parameters.
2, the dust barrier muffler muffler noise reduction effect than the other to be increased by 5%, and direct reduced fan noise.
3, the main performance silencer dust barrier is to prevent dust, coal dust into the fan directly to the front, thus extending the life of the fan silencer (1-2) years.
4, the series product specifications to meet a variety of models, specifications of axial local fans use.
5, easy installation, interface with flange connection, easy, reliable connection.
6, easy maintenance, easy to clean replacement parts.
