Negative-Pressure Fan Working Principle 1. Ventilating Principle The negative-pressure fan is used to exhaust air indoor, so the indoor air pressure is lowered, then there is a negative-pressure zone and the air outdoor will flow into the house for the air pressure difference; 2. Cooling Principle A. Cooling by air exchange: the fan exhausts the hot air indoor to even the temperature between indoor and outdoor; B. Combine with the evaporative cooling pads to reach a good ventilating-cooling effect.

Important Terms for Fan Selection Principle ★ Air Delivery: It is the amount of air that a fan will move under different conditions; also expressed as volume of air movement per unit time and the standard unit is cubic feet per minute (cfm). ★ Static Pressure: It is the pressure difference that a fan creates between the inside and outside of a mechanically ventilated structure. Fans create a vacuum in a house by exhausting air. The indoor environment with a lower pressure than outdoors will draw air in. This is a negative pressure system. ★ Fan Efficiency: It is the air delivery amount that a fan will provide per unit of electricity used and the standard unit is cubic feet per minute per watt (cfm/W).
