AP35 LN2 Ultrapure Fogger (Part # AP35)

AP35 LN2 Ultrapure Fogger is used in smoke studies and airflow visualization Studies in small semiconductor clean rooms, small pharmaceutical ISO Suites and industrial clean rooms. Ultrapure foggers combine nitrogen and water vapor to form a dense, ultrapure fog to visualize airflow turbulence; using liquid nitrogen and water (De-ionized water, WFI [water for injection] or sterile water. Below is a selection of foggers and performance details for each fogger, which you can match to your requirements for your smoke studies.

LN2 Ultrapure Fogger such as the AP35 uses 13.5 Liters of Di-Water, Sterile Water, or WFI Water. The AP35 has a 35 Liter LN2 Dewar. The Fog is produced by allowing the LN2 to boil, which occurs at room temperatures, thus releasing a nitrogen vapor. The nitrogen vapor is directed into the water cavity, which has a dual water heater that controls water temperature from 55C to 70C. The heated water emits water vapor, which then combines with the nitrogen vapor to form a very dense, highly visible fog. This fog is directed into your airflow by fog hose or fog rake to visualize airflow for smoke studies. The ultrapure fog is composed of 2-3 micron fog vapor droplets, and is very dense in visibility. Ultrapure fog is used to visualize airflow turbulence, airflow patterns, airflow uniformity and to locate dead airflow zones in clean rooms and around equipment.
