In fact, when analyzing the working performance of the clean module FFU , the main indicators which need to refer to include air quantity, overbottom pressure, noise and efficiency. There are correlations and mutual constraints between these parameters. That is, if you want to improve one of the performance parameters of the clean module FFU, you may need to reduce other part of performance parameters.
Next, we will share some main elements in this regard. In fact, we mainly judge the air quantity of the clean module FFU according to the sectional wind velocity. Considering the use requirements, it is generally reasonable to keep the sectional wind velocity in the range of 0.35 to 0.45 meters per second. For FFU with a specification of 1200 * 600 mm, the range of air quantity is about 910 to 1150 m3 per hour.
