Product Description

Product Description

The louver and dust filter are integrally designed, which facilitates the disassembly and installation of the filter.
The louver is made of aluminum alloy with a Polyester Powder Coating (PCC) surface, ensuring it won't rust in any harsh environment.
A comprehensive solution integrating rainproof, waterproof, snowproof, sandproof, and dustproof functions is provided.
The installation method is optional: external or internal (anti - theft design).
Protection level: IP54.

 

Structure

Application
 

NCC sand louvers are used in ventilation works.

Transformer/substation sound insulation room, radiator, boiler room

Ventilation louvers for radiators in construction machinery

Air intake air intake in the data center

Water pump room air intake

The vent on the soundproof enclosure

Fan vent

Ventilation system Air intake Air intake for outdoor units such as cooling towers

 

Our Advantages

The main features and benefits of NCC sandproof louvers are:

·NCC is the first and currently the only manufacturer in China whose louver series products have passed AMCA (Air Moving and Conditioning (Control) Association)  certification.

·Equipped with weatherproof sealing plate to prevent rain and snow infiltration.Equipped with rainproof and rust-proof material selection and surface treatment process.

·Louver ventilation improves indoor air quality.The modular design makes the louvers suitable for "vents" of any size.
It can be used as an independent barrier around the equipment or combined with building walls.Composed of prefabricated parts, it can be assembled in the field quickly and without welding.

·The horizontal layout of the sand shutter not only reflects the beauty, but also enhances the sand and dust prevention performance.Effectively prevent sand and dust from entering the room and adjust the indoor temperature and humidity.

·With steel structure design ability, with wind, snow load calculation ability, improve indoor safety.Meet anti-theft requirements and standards.

NCC's louvers have an energy-efficient aerodynamic design and very low pressure drop characteristics. The robust all-metal construction ensures the long service life of the NCC louvers.

The specification shown in Table 2 matches very closely desert type sand and dust, and illustrates an overall grade. Other grades of sand can also be used for the tests and are specified as follows:

a) FINE - sand between 106 and 150 um.              b) COARSE - sand between 355 and 425 um.

 

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.
