Clean Room Humidity Levels

What are the determining factors that will decide the level of cleanroom you need or if your operations would be better suited with a controlled environment instead.

Clean room humidity levels. Usually temperatures below 21 degrees celsius 70 degrees fahrenheit have a 2 rh band. The primary authority for clean room classifications is the international organization for standardization or iso. For successful construction drying humidity levels should fall between 25 and 55 with temperatures between 60 and 70 degrees f. In theory for an entire room to reach iso 6 air cleanliness you need to enter the cleanroom via an iso 8 ante room then go through an iso 7 to finally get into the iso 6 as shown in the image.

The smart fog es 100 system your humidification solution for clean rooms can be operated with clean levels of water and air according to the customer s requirements. Common cleanroom guidelines state that relative humidity rh levels in cleanrooms should remain between 30 40 rh year round. This will ensure temperature humidity and cleanliness levels are all effectively satisfied. Humidity airflow.

Iso 14644 1 cleanroom standards. In reality however you can reach an iso 6 clean room with 1 recommendation is 2 airlock. The humidity sensor the smart fog es 100 and accurately and reliably maintain the humidity without wetness. Hepa filters extricate 99 99 of all contaminants that are 0 3µm in diameter or larger.

Other hygrometers may also be used for specific applications. The air inside is constantly recirculated through high efficiency particulate air hepa filters. When maintained properly and in the right environment these filters can last upwards of 7 years before they have to be replaced. Controlling the humidity in your cleanroom is crucial not only to meet government and company specifications but to protect the integrity of your processes and product if the humidity is too high bacterial growth can flourish metal products or equipment can corrode photolithographic degradation can occur and condensation and water absorption can occur.

Rent or buy spot coolers to reduce humidity. A well designed barrier isolator is an alternative to an iso class 5 class 100 lafw device in an iso class 8 clean room. Understanding cleanroom humidity levels. The barrier isolator should be supported by adequate procedures for operation maintenance monitoring and control.
