Widely used in noise reduction ,such as ventilation, air conditioning system, low pressure fan, aerodynamic and so on.
It is widely used in special environments ,such as high floor hotels, purification workshops of factories, sterile rooms, food hygiene Ventilation and Air Conditioning Systems, high temperature, high-speed airflow, moisture, and dust.
1.Wx type in the low, medium and high frequency circumstance, its noise reduction is flat and large, especially in the low frequency circumstance.
2. The outer tube is made of galvanized metal plate, the inner tube is made of thin metal plate (drilled with micro-holes with a diameter of less than 1mm and a perforation rate of 1-5%), and the inner and outer tubes are reinforced and fixed by a grooved skeleton. Through the organic combination of different perforation rates on the micro-perforated plate and different cavity depths behind the plate, a relatively good noise reduction effect can be obtained in a wider frequency band.
