Centrifugle Fan ( Push-Pull Style)
Breeding chicken used push-pull fan through negative pressure ventilation, to ensured air quality and environmental stability in poultry houses, it is core device in breeding chicken environmental control system.
In breeding chikens,high temperature differences and high ammonia level can easily lead stress reactions in animals, then affecting efficiency of growth and health levels. Hansong Brand push-pull fan are designed for these questions. We according to aerodynamic principle, and work in conjunction with cooling pad, air inlet, and environmental control system to achieve directional airflow circulation, and exchanging air rapidly within the shed, and expelling ammonia, moisture, and heat in time, keeping stable environment inside the shed.
Working Principle Explanation
The push-pull fan adopts axial flow type blade design. When the fan is running,motor will drives six blades to rotate at high speed, creating a negative pressure environment inside the chicken coop,it will force outdoor fresh air to flow in evenly through the side wall inlet or cooling pads; simultaneously, stale air inside the chicken coop is forced out from the fan outlet quickly, achieving efficiency air circulation and temperature control.
Product Features and Advantages:
Compared with traditional exhaust fan, push-pull fan with 1100KW input power, can achieve 48,000 m³/h airflow output, and reduce energy consumption by 30% and expanding the coverage area to 150m2. Accoridng to real-world testing data shows that, in temperature of 30 degrees, continuous operation for 2 hours can lower the temperature inside livestock to below 26°C and reduce relative humidity from 85% to 65%. Its special design eliminates the need for disassembly during maintenance, improving maintenance efficiency by 50%, making it especially suitable for environments requiring frequent cleaning,for example chicken coops and pigsties.

Application
Hansong Brand push-pull fan widely used in breeding chicken rearing houses,laying houses,Negative pressure ventilation poultry houses,and new or renovated breeding chicken farming projects.
FAQ
1: Why does the push-pull fan suitable for breeding chicken farm?
Because breeding chickens are required high stable environment. Push-pull fans can remove harmful gases and moisture quickly, keep air quality good, reduce stress, and improve production.
2: What is the difference between push-pull fan and traditional exhaust fans?
Push-pull fans have automatic louver, provided good sealing when fans stopped ,and preventing back flow air, making them more suitable for requiring stable environmental control poultry houses.
3: How to calculate fans quantity are needed?
We need to calculate the ventilation volume according to houses’s length, width, and stocking density. then can provide fan quantity configuration plan for you.
4: Can it be used with cooling pads?
Yes. Push-pull fans usually used with evaporative cooling pad systems to form complete ventilation and cooling system.
5: Is it complicated for daily maintenance?
No,it’s easy. mainly involving regular inspection of belts,motors and cleaning dust.
6: Can it be connected to automatic environmental control system?
Yes. The push-pull fan can be connected with environmental control system, automatically starting and stopping according to temperature and humidity, achieving automatic management.
