Ultrasonic foggers are strongest when control, portability and repeatable localized delivery matter.

How ultrasonic fog is generated

Piezoelectric elements oscillate at ultrasonic frequency and atomize water into a visible aerosol. The resulting fog can be routed through hoses and wands to the point defined in the protocol. Output depends on the number and performance of the piezo devices, water level, temperature, electronics and airflow through the unit.

Where ultrasonic systems fit best

• Fume hoods and laminar-flow workstations
• Biosafety cabinets
• Glove boxes and barrier isolators
• RABS interventions
• Small and medium cleanroom areas
• Doorway, pass-through and localized turbulence studies

They are especially attractive when the facility wants on-demand operation without handling cryogenic liquid.

Water quality and operating discipline

Follow the manufacturer’s instructions for approved water. Applied Physics specifies DI water, sterile water or WFI for current CRF platforms. Do not assume ordinary tap water is acceptable. Drain, dry and maintain the reservoir as instructed to reduce residue, biofilm and avoidable failures.

Applied Physics CRF selection

CRF2 supports localized studies. CRF3 increases coverage for small cleanrooms and barrier systems. CRF6 provides substantially higher output through dual 80 mm outlets for medium-area studies.
