Smoke Studies Fogger

Smoke Studies Fogger or Cleanroom Fogger is a specialized device for airflow visualization, smoke studies, turbulence mapping, and leak detection in controlled environments. It reveals airflow patterns, laminar flow disruption, reverse flow, and dead air zones in pharmaceutical suites, ISO cleanrooms, compounding pharmacies, and semiconductor facilities.

 Ultrasonic foggers use piezoelectric transducers to atomize deionized (DI) water or Water for Injection (WFI) into microscopic water droplets. These water foggers support localized visualization around critical equipment, clean benches, biological safety cabinets (BSCs), gloveboxes, and barrier isolators without requiring liquid nitrogen.

Ultrapure liquid nitrogen (LN2) foggers combine liquid nitrogen with DI or WFI water to produce dense white fog. Their high fog volumes support long-distance visual tracking in larger cleanrooms and sterile processing areas. CO₂ foggers, glycol foggers, and portable handheld foggers provide additional options for HVAC balancing, localized airflow checks, and fume hood testing, depending on contamination requirements.

Airflow visualization studies support containment testing, cleanroom qualification, requalification, and contamination control. Video documentation records airflow around operators, equipment, and critical processes for assessment against applicable ISO 14644-3, EU GMP Annex 1, and USP <797> requirements.

Select a cleanroom fogger by comparing fog output, fog density, operating duration, portability, water compatibility, and coverage for the intended smoke study.
