Negative pressure fan is a cooling principle that utilizes air convection and negative pressure ventilation. It naturally sucks in fresh air through doors or windows, quickly and forcefully expelling hot indoor gases from the outside. It has the characteristics of high air volume, low noise, low energy consumption, smooth operation, long service life, and high efficiency. The air outlet is equipped with self hanging louvers, which can prevent outdoor natural wind and rainwater from flowing back. This product can be divided into three types based on material: galvanized sheet, stainless steel, and fiberglass, which are not easy to rust. Widely applicable for wall exhaust in industrial and mining enterprises, factory workshops, breeding venues, agricultural greenhouses, and entertainment venues.
