BY-ZK Microplate impedance composite muffler
The micro-hole impedance composite muffler is an anti-sounding product that combines the advantages of two mufflers, which are both resistive and resistant. It has a large muffling effect on medium and low frequency, and can be used to reduce the middle and low-grade fans in air conditioning systems and ventilation systems. When the noise has no corrosive effect on the metal surface and no dust, the air volume is 2000-6000m3/h.
PRODUCT DETAILS
First, the structural characteristics
It is made of a combination of sound absorbing cotton and glass wool covered galvanized microplate. Because the inner and outer tubes are made of galvanized sheet, it has the advantages of firmness, durability, beautiful appearance and strong rust resistance.
Second, performance
The muffler has a low R=10~15dB/m, the resistance system e-0.4 has an intermediate frequency R=15~25dB/m, the high frequency R=25~30dB/m, and the resistance loss: H=§V3r/0.2§(Pa).
