Product Description
NCC is a leading manufacturer of noise cancelling louvers worldwide, with sturdy, durable, and high-performance products that have been applied multiple times worldwide. The application scenarios of NCC noise cancelling louvers include:
Air inlet of ventilation system Air inlet of outdoor units such as cooling towers
Machine room air inlet Data center vents
Water pump room air inlet
Transformer/substation sound insulation room heat sink boiler room
Ventilation louvers for construction machinery radiators
Ventilation openings on soundproof enclosures
Wind turbine vent
Dimension & Appearance 
All doors are equipped with connecting locks, latches and handles (samples available or customized upon request)
The sound insulation door can be equipped with bird and insect screens as required
Doors can be coated with polyester powder coating
It can be galvanized steel, stainless steel, or aluminum
The main characteristics and advantages of NCC acoustic louvers are:
Equipped with weather resistant sealing plates to prevent the infiltration of rain and snow
The modular design can make the louvers suitable for use with any size of "vent"
It can serve as an independent barrier around equipment or be integrated with building walls
The blades of the silencing louver are arranged horizontally, reflecting aesthetics and enhancing acoustic performance
It can be equipped with stainless steel or galvanized bird nets, as well as insect nets
Meet anti-theft requirements and standards 
NCC's anechoic louver has an energy-efficient aerodynamic design and a very low pressure drop characteristic. The sturdy all metal structure ensures a long service life for NCC's noise reduction louvers. If necessary, we can also provide necessary supporting steel structures and provide comprehensive installation services.

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.
