Cone Fan (Butterfly Sytle)

In longitudinal ventilation systems, for chickens, It allows for faster airflow and air path longer, resulting in more evenly ventilation to everywhere in the poultry houses. Many high standard breeding farms upgrading their environmental control equipment,and usually choose this solution.

Specifications and Working Principle

When the normal exhaust fan starting work, the airflow will easily diffuse at the fan outlet, the extraction efficiency will weakening .

But this butterfly type cone fan, through its conical structure, will exhausts the airflow gathers, accelerates, and directly,reducing turbulence and backflow, results in stronger negative pressure effect and allows longer airflow distance.

Product Advantages

Actual improved extraction efficiency by 15%–30%

At the same power output,Hansong Brand butterfly cone fan achieves stronger ventilation effect . 

Extended the airflow path

This fan allows fresh air flow from the cooling pad end to the exhaust fan end all the way, resulting in more uniform ventilation.

Reducing airflow turbulence and backflow

Our butterfly cone fan improved the stability of negative pressure system.

More suitable for long distance breeder houses

The poultry house longer, the effect will be more obvious.

Working with evaporative cooling pad, air guide and air inlet perfect

When this fan work with cooling pad,air guide and air inlet,it is will form a high efficiency longitudinal ventilation system.

Applications

It is widely used in long-distance breeder rearing houses,layer houses,environmental control poultry houses,and some projects which required enhanced negative pressure

Frequently Asked Questions (FAQ)

1. Does the cone fan improve ventilation really?

Yes, It can improve exhaust efficiency significantly, especially in long poultry houses.

2. What is the difference compared to normal centrifugal push-pull fan?

Normally the centrifugal fans diffuse exhaust air, but the cone fan concentrate, accelerate, and direct exhaust air.

3. What is the length of poultry house is suitable?

When the poultry house is longer than 60 meters, The effect is very noticeable.  the longer the house, the more recommended it is.

4. Can it be combined with FRP exhaust fan?

Yes, many high-end projects use this combination : FRP fan and butterfly cone fan.

5. Does it will increase power consumption?

No, at the same power,it will improve ventilation efficiency level, making it more energy saving.
