Vertical Circulation Fan
Negative pressure fan is the use of air convection, negative pressure ventilation cooling principle, is a natural inhalation of fresh air from the installation site – the door or window, the indoor hot air quickly forced out of the outdoor, any poor ventilation can be improved.

Product Description
The vertical circulation fan is to circulate the air in the vertical direction , reduce the temperature difference between the upper and lower indoors, and make the indoor temperature uniform.
Due to their ability to deliver consistent air circulation, vertical ventilation fans are more increasingly used to create a constant airflow at animal and plant level. This fan also mixes the warm air from the ridge of a building with cold lower air, helping you save on heating costs.

Installation Diagram:
1. Circulate the air in the chicken house vertically to reduce the temperature difference between the upper and lower sides of the chicken house ,facilitate the temperature control of the chicken house ,and increase the feed-to-meat ratio or feed-to-egg ratio.
2. Reuse the hot air on the top of the chicken house to reduce heating costs

Application for Greenhouse:
Through air circulation to optimize the heat distribution and to reduce the humidity in the greenhouse, providing low-speed flowing air for crops better growth, reducing energy costs.
1.Circulate the air in the greenhouse vertically to reduce the temperature difference between the upper and lower sides of the greenhouse, facilitate the temperature control of the greenhouse.
