The greenhouse negative pressure fan accelerates the flow of air in parallel directions into vertical air flow, which can improve the ventilation effect in the greenhouse. Moreover, this type of fan does not require electricity, has no noise, and can operate for a long time, discharging hot gas, smoke, water vapor, etc. from the greenhouse. What are the advantages of greenhouse fans?
1、 To avoid wasting power, the equipment uses temperature differences and natural wind to rotate the equipment. It can rotate continuously with only a slight breeze or a temperature difference inside and outside the shed, without any need for electricity at all; The sensitivity of the device is very high.
2、 The greenhouse negative pressure fan has a long service life, which can be used for at least ten years; Moreover, the installation is convenient, and the negative pressure fan can be operated without a motor, with light weight and high exhaust efficiency.
3、 Maintenance free, negative pressure fan adopts fully sealed bearings, requiring no lubrication, and the equipment is sturdy and durable; High efficiency, requiring only a small amount of wind to effectively improve the temperature and humidity inside the shed.

When installing a negative pressure fan, the wall on this side of the fan must be properly sealed. Especially there should be no gaps around the fan. The most ideal method for installing a negative pressure fan is to close all the walls and nearby doors and windows on this side of the fan, and open the doors and windows on the opposite wall of the fan to ensure that the airflow flows in a straight line. The installation of negative pressure fans is a very important project, which has a significant impact on the future use of negative pressure fans. Below, the editor will give you some installation suggestions for negative pressure fans, hoping to be helpful to everyone.
Notes for Installation of Negative Pressure Fan
Before installation
Before installing the negative pressure fan, it is necessary to carefully check whether the negative pressure fan is intact and undamaged, whether the fastening bolts are loose or detached, and whether the impeller collides with the fan cover. Carefully inspect the fan blades or louvers for any deformation or damage during transportation.
When selecting the air outlet environment for installation, it should be noted that there should be no large obstacles within 2.5-3M of the opposite side of the air outlet.
During installation
3. Stable installation: When installing the negative pressure fan, attention should be paid to the horizontal position of the fan and adjust it to a stable level with the foundation plane. The motor must not tilt after installation.
When installing the negative pressure fan, the adjusting bolts of the motor should be in a convenient position for operation. Adjust the belt tension for ease of use.
When installing the negative pressure fan bracket, it is necessary to ensure that the bracket is level and stable with the foundation plane. If necessary, angle iron should be installed next to the negative pressure fan for reinforcement.
After installation
After installation, check if there are any remaining tools and debris inside the negative pressure fan. Use your hand or lever to move the fan blades and check for any signs of tightness or friction, as well as any items that hinder rotation. Only then can you proceed with the test run.
7. If there is vibration of the negative pressure fan or abnormal sound of “buzzing” or other abnormal phenomena in the motor during operation, the machine should be shut down for inspection. It should be repaired before starting up for use.
After the installation of the negative pressure fan, the surrounding sealing should be checked. If there are gaps, they can be sealed with a solar panel or glass adhesive.
