Product Description Product DescriptionNCC 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 We can provide acoustic louvre solutions to combat environmental noise problems in mixed commercial / residential areas, carrying out all relevant noise surveys and acoustic analysis.Detailed PhotosOur acoustic louvred screens result in a high performance solution to unwanted levels of noise, without the need for additional architectural cladding. Our AdvantagesNCC acoustic louvres are multi-purpose, permitting air to flow, whilst shielding the environment from unwanted noise.Our louvres are available in an array of standard modular sizes, meaning that a wide range of performance requirements can be met. By using our range of acoustic louvres, it overcomes architectural consistency issues, especially where space is limited. 1,Rugged all-steel galvanised construction. Stainless steel, aluminiumand other materials are also available.2,Inert, vermin-proof, weather-rated non combustible acoustic fill.3,Shaped splitter blade for maximum noise reduction with minimum pressure drop.4,Perforated splitter underside for maximum sound absorption.5,Weather stop inhibits rain/snow entry.6,300mm deep single banked systems and 600mm deep for the double banked system.7,Available in a variety of durable, attractive finishes,such as vinyl coated steel, polyester powder paint, anodised aluminium, galvanised and stainless steel.8,Modular sizes enable assembly of rectilinear louvre 'walls' of almost any size.9,Louvre blade orientation blocks horizontal line of site, enhancing both aesthetics and acoustic performance.10,Bird guards are available in galvanised or stainless steel, insect screens can also be supplied.Product ParametersSilencer--Sound Transmission Loss(dB) PageSilencer TypeFace VelocitySelf Noise(Lw)DIL,dBat250HzPressureopinN/m2Length(mm)Length(mm)m/sdB900150021003000900300016NFS5452231374714217718NFM53615233039476020N335152331419012222NSM33114212938507824NES533141931415511026NMS53612172332254728NFL53214172229202530NML5309141925122232NL53781316231217Laboratory TestingNCC 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.CertificationsPackaging & ShippingAll our packing with Rubber clip board,don't need to do fumigation.
