Installation and Maintenance of Casals Ventilation Fans


In the poultry industry, Casals Ventilation fans play an important role in achieving the highest productivity of birds in the yard. This is because day length and light intensity are often precisely controlled. Therefore, the light coming from outside the building is undesirable. For this reason, so-called Casals Ventilation Fans are designed to prevent light from entering the fan during operation. This article briefly introduces how to use ventilation fans for audiences. Light effect on the fan.

Find the Balance Between Light Transmittance and Air Resistance

A logical side effect of limiting light is to limit airflow. This is why Casals Ventilation fans are created with the following scales:

  • Light transmission resistance

  • Wind resistance

The dynamically shaped blades reduce airflow resistance. The ventilation fan is vertical to prevent dust and condensate from collecting. If not specified, it can eventually negatively affect the air flow.

Installation and Maintenance

The robust, easy-to-understand design of the Casals Ventilation fans allows for quick assembly and installation on all box and cone fans. The ventilation fan can be placed directly in front of the exhaust fan. Or in other words, it is connected to the suction side of the fan.  For example, it can be placed in the air inlet.

Measure the Properties of Various Ventilation Fans. Use A Wind Tunnel

Ventilation Capacity residual performance of the Casals Ventilation fans can be found by plotting the original fan characteristic curve with the ventilation fan resistance curve. The intersection of the fan function (the gray line) and the light-trap resistance curve (the red line) gives a new performance of the light-trap fan at 0 Pa (the black line). )

Calculation of Fan Efficiency

This article is part of the Casals Ventilation fans. In addition to the content of this blog, we also benchmark the performance of different types of fans. With ventilation fans under different conditions, we will explain what you need to pay attention to you read more
