Negative galvanized box fan greenhouse cooling exhaust fan

A negative pressure galvanized box fan is a type of fan commonly used in greenhouses for cooling and ventilation purposes. It helps maintain optimal temperature and air circulation inside the greenhouse, promoting healthy plant growth.

The fan is typically made of galvanized steel, which provides durability and resistance to corrosion in the humid and corrosive environment of greenhouses. The negative pressure system creates a pressure difference between the inside and outside of the greenhouse, facilitating air exchange.

The cooling exhaust fan works by drawing hot and stale air from the greenhouse and expelling it outside. This helps remove excess heat, humidity, and gaseous by-products produced by plants such as carbon dioxide. Fresh air from outside is then drawn into the greenhouse, aiding in cooling and providing essential oxygen for the plants.

The negative pressure galvanized box fan is often installed strategically at one end or both ends of the greenhouse to ensure proper air circulation. It can also be integrated with other ventilation systems, such as louvers or automatic controls, to optimize temperature and humidity levels.

Overall, the negative pressure galvanized box fan plays a crucial role in greenhouse cooling and ventilation, creating a favorable environment for plant growth and maximizing productivity.
