Product Overview: DWEX (WSP) Side Wall Fan

The WEXD series fan adopts advanced forward swept blades, low-noise external or internal rotor fan dedicated motor direct drive, and a square shell design that can be easily installed on concrete walls, brick walls, or light steel pressed wall panels. The square rain cover structure is firm and has a beautiful appearance. It has the characteristics of low noise, large air volume, reliable operation, wide range of performance parameters, and easy installation, and is widely used for side wall ventilation and air exchange in factories, mines, workshops, and civil and commercial construction projects. According to the requirements of the conveying medium, it can be made into anti-corrosion and explosion-proof types.

The WEXD (WEX) series fans are generally used for side wall exhaust, equipped with a 45 ° rain cover (or specially manufactured to 60 °) and insect proof mesh (to prevent insects from flying into the workshop through lights at night). The side wall air supply fan model can be made into DWSP (WSP) according to the needs, equipped with a 90 ° rain cover (windproof, rain proof, dust proof) and insect proof net (can prevent insects from flying into the workshop through lights at night). Accessory selection: Gravity check air valve (to ensure that the workshop remains isolated from the outside when the fan is not turned on), please specify when ordering.

Experimental verification

1、 Introduction to Tianhong Commissioned Experimental Laboratory (a large domestic wind turbine inspection laboratory):

1: Our laboratory has passed the qualification review of the Energy Efficiency Labeling Management Center of China National Institute of Standardization and obtained the qualification of Energy Efficiency Testing Laboratory for Ventilation Fan Energy Efficiency Labeling. After the fan products are tested by the center, they can be directly registered online and labeled with energy efficiency labeling based on the test report, and then produced and sold.

2: Our laboratory has 198 quality inspection projects for fan products, and the parameters have passed national laboratory accreditation and metrological certification.

2、 The power performance and noise testing laboratory ensures the accuracy of the results through the following methods:

1. Strictly follow standards such as ISO 5801 (GBT 1236), ISO 13350 (GBT 19843), ISO 5802 (GBT 10178) for design, construction, and testing operations;

2. The aerodynamic performance test adopts advanced multi nozzle method, replacing the traditional pitot static pressure tube to test flow rate, further improving accuracy;

3. The laboratory extensively uses new precision testing equipment and measuring devices;

4. Laboratory equipment and measuring tools have undergone strict calibration and regular re inspection and self calibration;

5. Multiple national level laboratories in China have conducted multiple "same machine inter laboratory comparisons" and participated in the capacity verification activities of ventilation fan testing laboratories carried out by national institutions.

3、 In addition to aerodynamic performance and noise detection functions, the laboratory also has the following testing capabilities:

1. Conduct impeller overspeed test according to JB/T 6445 Industrial Ventilation Fan Impeller Overspeed Test.

2. Conduct fan vibration testing in accordance with standards such as JB/T 8689 "Vibration Testing and Limits for Ventilators".

3. Conduct thrust testing on tunnel jet fans in accordance with the ISO 13350 standard for performance testing of industrial ventilation fans and jet fans.

Ensuring the efficiency of Tianhong's product research and development, reliable quality control, and improving the accuracy and authenticity of technical data.
