Greenhouse exhaust fan

In the section of greenhouse fan system and pad, detailed explanations about the efficiency of this system and these fans were provided. In this section, we will give a brief explanation about the types of greenhouse exhaust fans and the specifications and price of the greenhouse fan at your service.

First of all, we need to know the meaning of the word greenhouse exhaust fan. Exhaust Fan is a technique that, unlike blower fans, draws air in and out of the environment.

These fans cool the ambient air in addition to refreshing and removing the old air by sucking the greenhouse air which is humidified by passing through the cellulose pad system or by sucking the greenhouse air which has absorbed the moisture by the misting system.

This air suction is done by powerful motors that open the dampers using air force (weight fan) or through centrifuge (clutch fan).

Greenhouse fans are produced in dimensions of 100, 120 and 140 with different powers, of which the exhaust fan 140 is the most powerful, although the suction power of different companies differs from each other. In the Mazrae Bekr online store, you can see their types with full specifications.

Types of exhaust greenhouse fans in terms of mechanism:

1- 140 fan of weight damper type

   2- Fan 140 with clutch or damper with clutch

The difference between these two types of fans is that in a damping fan or damper, the dampers open with air pressure, but in a clutch fan, the clutch mechanism opens the dampers as soon as the fan is turned on, which can be done in wet areas. The fan was also used to reduce or drain the greenhouse moisture and change the greenhouse air.

When choosing a greenhouse ventilator, its isolation when it is off, endurance, durability, volume, etc. are important points that must be paid attention to.

Calculate the number and type of fan suitable for each greenhouse

Calculating the right number and type of each greenhouse depends on a series of factors, some of which we will mention below:

1- The minimum and maximum temperature of the greenhouse

2- Intensity of light radiation flow based on luxury

Relative humidity of the area-3 

4- Intensity and direction of wind flow in the region

5- Required temperature

6- Fan height

7- Pad width or thickness

8- Structure height

9- Length and width of the greenhouse opening

10- The height of the culture bed

11- Type of fan in terms of suction power, engine speed, fan dimensions, etc.
