NCC rectangular and cylindrical pipe silencers provide more effective, accurate and economical noise reduction solutions compared to other noise reduction methods, because all NCC products are derived from strict laboratory and field tests. In addition, NCC-made pipe silencers strictly control manufacturing tolerances and the use of noise reduction materials to achieve stable noise reduction effects.
NCC can provide acoustic solutions to solve environmental noise problems in mixed commercial/residential areas. It can provide all related noise acoustic analysis, ventilation pressure loss calculation, product structure verification, air and fluid simulation services.
Over the years, the continued success of our products and services has enabled the NCC brand to earn a consistent reputation for quality and performance among a wide range of customers, be they multinationals or independent family businesses. This is due to the expertise and passion of our Boheng people, as well as the excellence of our products.
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.
NCC Acoustics' silencers are rated under the working conditions of state-of-the-art acoustic research and development laboratories. Regardless of its size or configuration, our silencers are developed, tested, and rated according to the latest industry standards.
