Product description

The noise attenuation radiation of 100 blades is reasonably set, and the noise is absorbed by a micro-hole piston acoustic absorption resonator on the lower side of the blades. The product has a wide noise attenuation frequency band, which can meet the requirements of ventilation and heat dissipation, daylighting, enclosure and control of noise radiation. The noise reduction capacity is 5-15db (A), pressure loss ≤30Pa, and the applicable flow rate is 1500m3/h-3000m3/h per square meter. Main features: one hundred blade design, ventilation resistance is small, rain, noise absorption, and has the characteristics of fire, rain, moisture, beautiful and generous.

2, use

This product is widely used in ventilation cooling requirements higher place of ventilation and air conditioning systems, return air corridor mouth, no return air duct room return air mouth, the return air mouth of the pipe ends, cooling tower air vents, air conditioning, noise elimination, noise barrier, vents silencing of cooling devices and other equipment room into the ventilation window, etc.
