Smoke Studies and AP35 Ultrapure Fogger
In 2001 portable cleanroom foggers were introduced and now the AP35 LN2 fogger is a significant advancement with 3X more ultrapure fog volume, adjustable fog volume control, adjustable airflow control and wireless remote control. The AP35 uses liquid nitrogen and deionized water, sterile water or Water for Injection to create a very dense, ultra pure fog to provide superb visualization of airflow patterns, flow direction, turbulence and dead zones for up to 70 minutes in clean rooms, ISO suites, sterile rooms, barrier isolators and medical rooms. The AP35 provides 5 cubic meters ultrapure fog per minute with about 571 ml fog density each minute, superb for visualizing airflow and turbulence. More than 20-30 feet of air flow visualization is provided in the clean room using two 80mm fog outputs. 3D airflow modeling is accomplished very well and no contamination is created and no clean up of any kind is required after visualizing the airflow. The AP35 ultrapure LN2 fogger supports airflow visualization guidelines as defined by USP797 Insitu Airflow Analysis, ISO 14644-3, B7; Federal Standards 209E and its replacement ISO Standard 14644-1 and 14644-2.
