WEXD Explosion proof Wall Axial Flow Fan Low Noise Industrial Exhaust Fan

WEXD seriesExplosion proof wall axial flow fanExplosion proof fan (hereinafter referred to as "explosion-proof fan") is a derivative product of WEX, and its explosion-proof performance complies with the provisions of GB3836.1-2010 "Explosive Environment Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Environment Part 2: Equipment Protected by Explosion proof Shell". It is made into an explosion-proof type with the explosion-proof mark "Exd Ⅱ BT4 Gb".

2. Side wall fans are generally used for side wall exhaust, equipped with a 45 ° rain cover (or specially manufactured to 60 °) and insect proof nets (to prevent insects from flying into the workshop under light 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.

3. The side wall fan adopts forward swept blades and low-noise external or internal rotor fan motor direct drive. The square shell design 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.

1. Before installation, it is necessary to carefully check whether the ventilation fan has been damaged or deformed due to packaging and transportation. If there is any damage or deformation, it should be repaired properly before installation can proceed.

2. During installation, it is important to check for any looseness in the connecting parts. The gap between the blades and the air duct should be even and there should be no rubbing or collision.

3. Check whether the insulation performance of the motor is good, and the ground resistance should be greater than 20M Ω. The fan should be reliably grounded.

4. After installation, a trial run must be conducted first, and formal use can only be allowed after normal operation.

5. When wiring or repairing explosion-proof ventilation fans, it is strictly prohibited to open the cover with power on! It is strictly prohibited to damage the explosion-proof device

6. Before using the explosion-proof ventilation fan, it should be checked whether there is an explosion-proof mark and explosion-proof certificate number, and whether the explosion-proof mark is suitable for the operating environment.

7. The fan should be inspected regularly, and any damaged parts should be replaced promptly.
