What is the difference between cleanroom air outlet and return vents?

Many people can not distinguish between the clean room air outlet and return vent, do not know the specific difference them, in fact, as the name suggests clean room return vent is the clean room air return device, air outlet is the clean room air supply device.The following to talk about the specific differences. Cleanroom high-efficiency air  outlet: Cleanroom air outlet will be configured with high efficiency filters, generally become a high efficiency air supply outlet. High-efficiency air outlet is a clean room terminal filtration device, it can be said that it is to meet the purification requirements of the key, is currently widely used in medicine, electronics, food and other industries.It is the key to meet the purification requirements, is now widely used in medicine, electronics, food and other industries.I do not know if you have ever understood the structure of the high-efficiency air measuring port, many high-efficiency air outlet  is used in the face-to-face structure, so that it is easy to produce around the seam leakage,DERSION developed a patented technology, high-efficiency air  outlet using a one-piece box structure design, is the line across the structure of the air supply outlet steel plate is directly inserted into the sealing strips, if it is a liquid tank is directly inserted into the jelly glue, so that you can Zero leakage in the true sense of the word. This compact overall structure design, not only save the colour steel plate material, installation of high-efficiency air supply outlet installation is easier and faster. 2.Steel Return Vents Return Vents can be said to meet the clean room air volume indispensable products, the traditional clean room return vents use aluminium screws to fix the outer frame, with aluminium louvre return grille.This return vents without a filter, and if the return air volume is large back to the air louvre will have noise and easy to deform, in order to solve these problems caused by the disturbance, DERSION cleanroom return vents generally  use the steel return air inlet. We innovate on the basis of the original, not only firm and durable, but also beautiful and generous.
