poultry shed ventilation fan

 The principle of ventilation and cooling of exhaust fan
The technology derived from Europe, standard and manufacturing process is whole in accordance with the European CAD/CAM. exhaust fan is installed in one side and evaporative cooling pad is installed in the other side ,then heat and exhaust inside will be taken away because of negative pressure, and fresh and filtered air will be pumped into through pad to make the air cool down by natural physical phenomenon----evaporation.
The combination of exhaust fan and evaporative cooling pad can sustain the factory temperature in less than 28 Degree and make air change 80--90 times per hour, no matter how high the original temperature is.

Application:
Our exhaust fan can be used in almost all places which need ventilation and cooling.
1. Industry: garment manufacturing factory, electronics, plastic, shoe, toy, hardware factory and so on
2. Commerce: hall, supermarket, hotel, net bar, recreational place, guesthouse.
3. Public: hospital, station, gym, school
4. Animal husbandry: poultry house, pig, chicken, rabbit, cow barn
5."Cooling pad + ventilation fan" tunnel ventilation is the most economical and efficient cooling way in summer. Reasonable design and installation of cooling pad with ventilation fan can control the temp at 30 degrees in the poultry house even at the hottest weather.
