Silencing static pressure box (louver)

Detailed introduction of soundproof static pressure box (louver)

The soundproof static pressure box is a necessary accessory for the air supply system to reduce dynamic pressure, increase static pressure, stabilize airflow, and reduce airflow vibration. It can make the air supply effect more ideal. It mainly uses glass wool or other sound-absorbing materials. The surface of the static pressure box is covered with sound-absorbing materials, which can eliminate the airflow noise at the air outlet and prevent crosstalk between adjacent rooms. The soundproof capacity is 5-10dB (A). ZHXS.XJY-2 type is suitable for long return air outlets with a B-side width of less than 200mm.
The soundproof static pressure box is an essential accessory for the air supply end. The main air duct is supplied through a hose or directly connected to the diameter of the static pressure box. A valve is installed here to control the air volume entering the static pressure box, increase the system's static pressure, stabilize the airflow, and make the airflow organization more reasonable, achieving the ideal air conditioning effect. Using glass wool or other sound-absorbing materials, the surface of the static pressure box is covered with sound-absorbing materials, which can eliminate the airflow noise of the air outlet and prevent crosstalk between adjacent rooms. The noise reduction capacity is 5-10dB (A). ZHXS.XJY-2 type is suitable for long return air outlets with a width of 200mm on the B side.
