NCC Silencing Air Duct is a necessity in air handling systems. The emergence of high-performance HVAC equipment has led to unacceptable low-frequency and high-frequency noise pollution, which has created a need for stricter noise control in air conditioning systems. High-performance mufflers offer the most effective and economical solution, and air handling component manufacturers provide more reliable noise data. Therefore, using silencers accurately rated under operating conditions helps achieve the required noise standards. NCC's silencing air ducts are rated under the working conditions of the most advanced acoustic research and development laboratory. Regardless of its size or configuration, our silencing air ducts are developed, tested, and rated in accordance with the latest industry standards.

Effective noise reduction
It can significantly reduce the noise generated during the operation of the air duct system, providing a quiet and comfortable indoor environment.
Improve air quality
While reducing noise, it does not affect the normal circulation of air, ensuring a good ventilation effect and thereby improving indoor air quality. 
Energy-saving and efficient
The optimized air duct design reduces wind resistance and lowers the energy consumption of the fan, helping to save energy costs.,
Strong stability
It has good compression and deformation resistance capabilities and can maintain good performance and shape during long-term use.
Good fire performance: Made of fireproof materials, it can prevent the spread of fire to a certain extent and improve the fire safety of buildings.
Long service life
High-quality materials and excellent manufacturing processes give it a long service life, reducing the frequency of replacement and maintenance.

Laboratory Testing

NCC Acoustic Laboratory - A Laboratory Professionaly Committed to Serving Customers

      We exert every ounce of our strength to construct a high-end, avant-garde laboratory endowed with autonomous control capabilities.   For all bespoke products, be it in terms of specifications, dimensions, or acoustic requisites, prior to entering the mass production phase, we shall enforce rigorous and meticulous pre-production sample testing procedures.   Only upon thorough confirmation that all indicators are up to par will we invest a considerable amount of human and material resources to embark on mass production endeavors, thereby effectively guaranteeing that each and every batch of large-scale goods delivered to clients possesses outstanding quality.

  The fabricated product samples are positioned within the spacious window of the laboratory and securely fastened through professional sealing measures.   Through precise adjustment of the relevant parameters and concurrent utilization of advanced and precise apparatuses for comprehensive and profound testing, it is ultimately ensured that the products can fully comply with the exacting requirements of customers.
    As depicted in the illustration, the external noise of the laboratory attains 80.1 dB, while through random measurement, the internal acoustic laboratory drops to 36.4 dB or even lower.   The elevated standard of sound insulation not only ensures the accuracy of the experimentation but also furnishes a robust guarantee for the test outcomes.
