Product Overview: The Longyu Silencer Static Pressure Box is manufactured by Dezhou Longyu Air Conditioning Equipment Co., Ltd. It is constructed from galvanized materials into a square or cylindrical shape, lined with sound-absorbing material and an interior perforated plate, with external flanges on both ends.
Working Principle: Based on the principle of air molecules impacting the pipe wall to generate static pressure, when airflow enters the static pressure box, the space expands, velocity decreases, and part of the dynamic pressure is converted into static pressure. The sound-absorbing material inside the box absorbs sound waves, while the external surface reflects sound waves, thereby reducing noise.
Product Functions
Dynamic to Static Pressure Conversion: Converts part of the dynamic pressure into static pressure, improving air supply efficiency and enabling air to be delivered farther.
Noise Reduction and Silencing: Internal sound-absorbing materials and special structure effectively absorb and block noise, reducing wind noise, with a noise reduction capacity of up to 10-20 dB(A).
Uniform Air Distribution: Provides uniform pressure to branch pipelines, ensuring even air supply from outlets.
Reduction of Dynamic Pressure Loss: Minimizes dynamic pressure loss in ventilation and air conditioning systems, enhancing overall system performance.
Universal Connector: In ventilation systems, it can be used to connect ventilation ducts for transitions such as square to round, round to square, diameter changes, right-angle turns, and multi-pipe junctions, simplifying the system.
Product Features
Excellent Sound Absorption: Utilizes high-quality sound-absorbing materials to effectively absorb and block various types of noise.
Simple Structure: Square or circular design with external flanges, offering a straightforward structure that is easy to install and maintain.
Easy Installation: Can be conveniently installed at suitable locations in ventilation systems according to actual needs.
Application Range: Widely used for noise reduction in equipment and machine tools, connecting axial fans for sound absorption and noise reduction, various indoor spaces, mines, and ventilation and smoke exhaust systems in chemical workshops.
