May 22, 2019 Industry News 364 views

Cleanliness refers to the amount of dust (including microorganisms) in the clean air

The air cleanliness of the clean room generally requires the following tests to draw conclusions:

l   Idle, static test

The clean room has been installed, the clean air conditioning system is in normal operation, and the indoor production equipment and operators are not in place.

Or the clean room purification air conditioning system is already in normal operation, the process equipment has been installed, and the test is carried out without production personnel in the room.

l   Run, dynamic test

The clean room has been tested under normal production conditions. The detection of air volume, wind speed, positive pressure, temperature, humidity, and noise in the clean room can be carried out in accordance with the relevant regulations of general use and air conditioning.
