Product Description

The advantages and key points of using Negative Pressure Fan for ventilation and cooling in summer workshops:

Generally, in summer, the temperature in the workshop is high and the ventilation is poor. The installation of Traditional Ceiling Fans is not ideal. Traditional fans have small air volume and large power output, and the installation effect is also not good. Negative pressure fan can help you solve the problem of stuffiness.

The installation height of negative pressure fan in Industrial Fans should be high, because the workshop temperature is high and the temperature difference is large. The negative pressure fan is installed below, and the hot air has already risen to the roof. So for workshop cooling, the installation position should be high, and the air inlet should be installed large enough to not be less than 1:4 compared to the fan outlet. The position of the air inlet should also be installed reasonably, and the direction and specific location should be determined based on the actual situation of the workshop.

In addition, the ventilation frequency should also be set well, and only 10-20 ventilation designs are required for the workshop. If a negative pressure fan is needed to cool down, it needs to be designed at least 50 times.
Industrial Exhaust Fan

Attention should also be paid to the selection of negative pressure fan for ventilation and cooling in the workshop. Belt type negative pressure fan should not be installed because the belts will quickly age under high temperatures and will not be damaged in a long time. High temperature motors should also be used because the workshop temperature is high, and the motor may also experience temperature rise during operation. It is best to choose die-cast aluminum fans for the fan blades, as engineering plastic fans will quickly deform due to high temperatures.

The distance between the fan water curtain and the wall should be greater than 30CM to avoid obstruction of airflow entering the wet curtain on that side. There are generally two types of fan water curtain ventilation methods: vertical and horizontal. Horizontal ventilation has a large airflow cross-sectional area and low wind speed, which can easily cause large dead corners. However, vertical ventilation has a small airflow cross-sectional area, high wind speed, and very small dead corner area. If conditions permit, advanced longitudinal ventilation methods should be used as much as possible.
