The importance of negative pressure centrifugal fan. Basic elements of negative pressure ventilation: It is to assemble a negative pressure centrifugal fan at one end of an independent space, which may be able to provide external ventilation system equipment. Aluminum alloy doors and windows are opened at the front or far side of the centrifugal fan as the air inlet, allowing air to circulate in the positive direction of the fire exhaust fan, and allowing the gas in this area to undergo convective heat transfer. This is called negative pressure ventilation—— In short, discharging is negative pressure ventilation.

Importance of negative wind pressure equipment

(1) Immediately remove excessive heat generated in the workshop;

(2) Immediately remove industrial waste gas and odors from the workshop;

(3) Immediately remove smoke and dust from the workshop;

(4) Immediately remove excessive moisture from the workshop to reduce discomfort with corrosion management methods for equipment;

(5) Improve the oxygen content in the workshop, enhance work efficiency and production capacity;

(6) Ventilation in the room can prevent the gathering of influenza viruses.
