The exhaust fan realizes the automatic opening and closing of the fan louvers through the automatic control system, achieving dust-proof, waterproof and beautiful effects. It has low noise, large air volume, low power consumption, and obvious cooling effect. It can be used for both blowing and exhausting. It is the best choice for cooling and ventilation in factories and other places.
Cooling pad is an efficient and economical cooling method through evaporation. Hot and dry air enters the room through the cooling pad. Since the inner hole wall of the cooling pad is evenly covered with water film, when the outdoor fresh air passes through the cooling pad, the water on the cooling pad will absorb the heat in the air and evaporate, making the fresh air The temperature drops and the humidity increases, completing the cooling process, making the air in the factory cool and moist.

1. Generally speaking, it is best to install the equipment on the exterior wall of the building to shorten the convection distance as much as possible.
2. The equipment can be installed on the wall or window sill, but the installation environment should ensure smooth and fresh air. The cooling pad should not be installed at the exhaust outlet with smelly or peculiar gases. If there are no windows or doors for sufficient ventilation, wall holes must be opened for exhaust ventilation to ensure the required air volume of the factory.
3. The exhaust fan is installed 1m~1.5m away from the ground to ensure convection at an appropriate height and create a refreshing environment.
4. There are generally two installation methods of exhaust fan + cooling pad ventilation system: vertical and horizontal.
5. Make sure that the installation position of the exhaust fan cooling pad system is stable and the frame structure is strong enough to support the weight of the entire equipment and maintenance personnel.
1. Before installation, first weld the bracket with angle steel. Its reference size is determined by the size required for on-site installation, and fix it at the location to be installed with six M10 expansion screws and two M10 wall bolts.
2. Due to the safety of people entering the machine during maintenance and the need for the stability of the fan itself, it is advisable to use 40*40*4 or 50*50*4 angle steel.
3. The installation drawing should be used as the standard during installation, and the drawing should be optimized and installed based on the actual conditions of the installation site.
4. The specific installation steps of exhaust fan cooling pad are as follows:
The first step is to remove the window where the exhaust fan or cooling pad is to be installed, and clean the inner frame of the window.
The second step is to install the exhasut fan or cooling pad. Before installation, first weld the bracket with angle steel. The fan and cooling pad must be installed horizontally, and the fixing screws must be strong and reliable. After installing the cooling pad, be sure to seal the edges with glass glue to avoid affecting the convection effect.
Next, the exhaust fan is installed on the longitudinal window sill of the water cooling pad convection. After the fan is installed and fixed, a protective net must be installed at the air outlet to prevent people from coming into contact with the wind wheel and causing danger.
The third step is to arrange the water pipes and water tank pumps according to the construction drawings and actual conditions.
1. Each exhaust fan is suitable for cooling a room of 70-100㎡.

2. Before using the exhaust fan + cooling pad system, check whether there are paper scraps, dust and other debris in the cooling pad and pool. They should be cleaned 6-10 times per year during use. The cooling pad is rinsed directly with the faucet. The water added to the pool should be tap water or other clean water to keep the pipelines smooth and the cooling pad high efficiency.
3. The motor is the heart of the fan. If a malfunction occurs, cut off the power supply immediately and ask an electrician to repair it promptly. When installing, be sure to connect the ground wire to ensure personal safety. Be careful when disassembling the impeller to prevent the blades from deforming and colliding with the box.
4. The float valve in the pool or water tank should ensure that it can automatically replenish water when the water level reaches the lower limit, and cut off the water when the water level reaches the upper limit. If the float valve control fails and it is found that there is a lack of water in the pool or water is dripping even when it reaches the highest water level, it should be adjusted or replaced in time.
5. If it is found that the water supply to the cooling pad is insufficient or uneven, check whether there is a lack of water in the pool, whether the water pump is running, whether the water supply pipeline and the water pump inlet can pass water, whether the small holes in the water supply pipeline are blocked, and check whether the spray Is the water pipe located in the center of the cooling pad? The normal water spray height should be greater than 80mm.
6. Since the fan is a low-pressure type (both static pressure and dynamic pressure are small), it is not possible to use an extended pipe at the outlet of the exhaust fan of the blinds to supply air over a long distance.
7. The circuits of fans and water pumps should be controlled centrally, and the control switches should be installed indoors.
8. After the louver exhaust fan is installed, the rainproof louver cover should be fastened to prevent the cover from being blown off by strong winds.
9. When the cooling pad is not in use in winter, drain the water in the pool or water tank, and wrap the cooling pad and box with plastic cloth or cotton cloth to prevent wind and sand from entering the room.
