Sand Proof Louver - Block Outdoor Sand and Dust From Entering

Product Description

Product Description

    The integrated design of the ventilating louver and dust filter adopts aluminum alloy material throughout.which can prevent corrosion caused by long-term exposure and extend the service life of the equipment.
 
    The single S-shaped structure of its blades ensures air ventilation while achieving reliable water and sand resistance.

Applicantion Scenarios

    Sand-proof louvers are widely suitable for various buildings in sandy and windy environments, with specific applications as follows:
 
  1. Desert Highway Service Areas & Border Posts: They protect indoor ventilation systems and electrical equipment, preventing sand and dust from blocking pipelines and abrading components.
 
  2. Mining Workshops & Inverter Rooms of Photovoltaic (PV) Power Stations in Gobi Deserts: While ensuring efficient heat dissipation and ventilation for equipment, they block the intrusion of mineral dust and sand particles, thus maintaining the stable operation of equipment.
 
  3. Exteriors of Civil Residences, Schools & Hospitals in Arid Areas: They can replace traditional window guards. On one hand, they keep indoor air fresh; on the other hand, they block outdoor sand and dust from entering, effectively improving the comfort of living and office spaces.

Our Advantages

The main features and benefits of NCC sandproof louvers are:

    1. Designed for arid, semi-arid and sandstorm-prone areas, it features sandstorm and abrasion resistance.

    2. Both the louver blades and dust filtration devices are made of aluminum alloy, which will not rust under any harsh environment.

    3. Has a service life of more than 20 years. Daily maintenance only requires regular and simple cleaning of the blade surface, resulting in extremely low maintenance costs.

    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 μm.

                                                                                                                b) COARSE - sand between 355 and 425 μm.

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.
