Product Details

    Product Description

    Sound Elimination Louver contain Arc Sound Elimination Louver and Oblique Sheet Type Sound Elimination Louver.

    Arc sound elimination louver is riveted with upper and lower sound absorber, arc sound absorber and side plate, and sound absorber is the pore plate externally wrapped with melamine and other sound absorption materials. Arc sound elimination louver is applicable to various air vents of plants.

    Arc sound absorber adopts oval louvre blade design, and has small ventilation resistance, and upper blade can prevent the entry of rainwater, and lower blade can effectively absorb the noise; it is characterized by fireproof, rainproof and dampproof property and good-looking appearance.

    Oblique sheet type sound elimination louver is riveted with upper and lower sound absorber, oblique sheet sound absorber and side plate, and sound absorber is the pore plate externally wrapped with melamine and other sound absorption materials. Oblique sheet type sound elimination louver is applicable to various air vents of plants.

    Oblique sheet type sound absorber adopts rhombic louvre blade design, and its ventilation resistance is larger than that of arc sound elimination louver, and sound elimination effect is better than that of arc sound elimination louver. Upper blade can prevent the entry of rainwater, and lower blade can effectively absorb the noise; it is characterized by fireproof, rainproof and dampproof property and good-looking appearance.

    1. For commercial buildings and industrial plants, large air flow must be taken into account, and these airs are used for cooling and supplying air compressor or generator, and for ventilation and air conditioning system.

    2. In many ventilation systems, the equipment will make strong noise while producing airflow, so the problems encountered by designers and engineers are to allow ventilation, and prevent the transmission of noise outwards. Especially lower pressure drop requirements and effective noise prevention requirements are very important evaluation standards. At the meantime, the economy, good-looking appearance and practicability as required by architect should also be taken into account.

    3. Air vent of factory workshop, air inlets of cooling tower, compressor room, power station, substation, exhaust chamber, diesel engine unit room, parking lot, air conditioning unit, natural ventilation area and condensing unit, air inlet and outlet window of equipment room, ventilation & heat dissipation window of sound insulation hood of strong noise equipment, and local air vent of sound barrier.

    Standard design, multiple models, dimensions and exterior finishes are suitable for all industrial and commercial engineering projects with ventilation and noise reduction requirements.

    Laboratory

    As the key environmental protection laboratory in Sichuan Province, our acoustical laboratory covers 521 square meters, and is composed of reverberation chamber, sound insulation chamber, silencer dynamic evaluation laboratory and impedance tube laboratory. The laboratory now is the largest noise control technology and acoustic material research & test center in southwestern China, and leads domestic noise control field. Silencer dynamic evaluation laboratory now is the largest silencer test platform in China. 

    Our laboratory is designed by architectural acoustics design team from Tsinghua University based on relevant national standards and by reference to well-known acoustical laboratories at home and abroad. Main measurement instruments are manufactured by B&K, Denmark (a measurement instrument manufacturer ranking No.1 in the world, and providing noise and vibration solutions). The laboratory conforms to the testing conditions of CMA (China Metrology Accreditation), and has issued the reports conforming to CMA requirements for customers, and especially plays an irreplaceable role in the development of new productions and the detection of product quality. 

    Our laboratory has established a resource sharing and advantage complement relationship with several institutions, e.g. Architectural Physics Laboratory of Tsinghua University andAcoustics Institute of National Institute of Measurement and Testing Technology, etc., and does business with them in product R&D, performance detection and other fields.  

    The objectives of our laboratory are to correctly evaluate the sound absorption, sound insulation or sound elimination property of each kind of noise reduction product or structure with various measurement methods, support the design and optimization of noise reduction scheme, and ensure the noise of noise reduction engineering really meets the standard!
