Product Description
Anti-Sand Louvers are purpose-built functional building ventilators for sandy environments, combining ventilation, lighting, and sand-proofing in one.
⦿Anti-sand louvers, characterized by their specialized blade angle configurations and streamlined structural design, achieve efficient interception of airborne sand and dust particles (encompassing fine sand, dust, etc.) while maintaining unobstructed air circulation.
⦿In terms of materials, aluminum alloy is predominantly utilized, subjected to anti-corrosion treatments. which possesses lightweight and rust-resistant ability, and can withstand sand friction, UV exposure and extreme temperature difference.,
⦿In terms of structure, the tilt angles of the blades are precisely calculated, ensuring they neither impede ventilation nor compromise the maximum sand-blocking efficiency. The frame design prioritizes load-bearing capacity and installation stability, making it suitable for high-wind-pressure areas.
Application Scenarios
Targeted solution to sand and dust problems:
· Civil Building Protection Solutions
Suitable for residential buildings, commercial buildings, and hotels in arid regions, they effectively control sand and dust intrusion into indoor spaces and maintain the cleanliness of living environments.
· Energy Facility Protection Systems
Provide professional protection for outdoor equipment rooms in wind farms, photovoltaic arrays, and petrochemical plants, ensuring that key equipment such as generator sets and electrical control units are protected from sand and wind erosion.
· Transportation Infrastructure Protection Measures
Ensure the normal operation of tunnel ventilation systems and communication base stations along railways and highways, preventing pipeline blockages and equipment performance degradation caused by sand accumulation.
Our Advantages
· It typically adopts corrosion-resistant and wear-resistant aluminum alloy materials, capable of withstanding long-term sand erosion, ultraviolet radiation, and featuring a long service life with low maintenance costs.
· The ventilation louver and dust filter are integrated in design, making the disassembly and installation of the cotton filter convenient.
· The blades feature a single S-shaped structure, with both waterproof and sandproof functions.
· The installation methods include external mounting and internal mounting,it can be flexibly adapted to building structures and equipment layouts.
· The filter cotton includes white cotton and black cotton,the replacement of filter components is convenient.

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.
