In the fan system and the greenhouse pad, a detailed description of the performance of this system and these fans is presented. In this section, we will give you a brief description of different types of greenhouse exhaust fans, features, and the price of the greenhouse fan.
First of all, we need to know the name of the greenhouse exhaust fan, which, in contrast to the blower fan, by absorbing the air; it puts air out of the environment.
These fans cool the air in addition to refreshing and exhausting the air in the greenhouse suction, which is wetted through the cellulosic pad or through the air in the greenhouse absorbed by the moisture mist system.
This air suction is carried out through high-power engines that open the damper by using air force of the air (weight fan) or centrifugal (clutch fan).
The greenhouse fan in the sizes 100, 120 and 140 with different powers are produced, which is the most powerful exhaust fan 140, which, of course, the suction power of the fan, different companies different from each other, you can see the types of them with full specifications in the online store of the Mazrae Bekr.
The types of greenhouse exhaust fans in terms of the mechanism:
1. fan 140 type of damper weight
2. fan 140 clutch or damper clutch
The difference between these two types of fans is that in a Fan damper, the damper opens with air pressure, but in the clutch fan, the clutch mechanism, as soon as the fan is turned on. In the wet areas, this fan can be used to reduce or dehumidify the greenhouse and change the air in the greenhouse.
When choosing a greenhouse fan, you should be careful:
being isolated when it’s off, stamina, durability, volume, and so on.
Calculate the number and type of fan appropriate for each greenhouse
The calculation of the number and type of each greenhouse depends on a number of factors, which will be referred to below by some of them:
1. Minimum and maximum air temperature in the greenhouse
2. Relative humidity of the area
3. Light intensity flux based on luxury
4. Intensity and direction of wind direction of the region
5- The required temperature
6- Fan height
7. Width of the pad or thickness
