玻璃钢负压风机是运用空气对流，负压换气的原理来设计，使用玻璃钢负压风机，安装在通风不良的对向，可以将室内停滞不重的热气、异味、乌烟、秽气，在最短的时间内迅速排出室外。使室内温度降低到与室外温度相同，却能感觉到比室外更凉爽，使用玻璃钢负压负压风机之后，可以让空气动起来，每小时换气次数能够达到60~120次，可以给你创造一个通风流畅、空气清新、良好舒适的工作环境，彻底改善室内闷热、异味、乌烟、秽气等问题。
Glass fiber reinforced plastic negative pressure fan is designed by using the principle of air convection and negative pressure ventilation. It is installed in the opposite direction of poor ventilation, which can quickly discharge indoor stagnant hot air, peculiar smell, smoke and filth out of the room in the shortest time. The indoor temperature can be reduced to the same as the outdoor temperature, but it can feel cooler than the outdoor temperature. After using the glass fiber reinforced plastic negative pressure fan, the air can be moved, and the air exchange rate can reach 60 ~ 120 times per hour, which can create a smooth, fresh and comfortable working environment for you, and thoroughly improve the indoor sultry, peculiar smell, smoke, filth and other problems.
