CleanRoom Fogger Model CRF-4

The Clean Room Fogger (CRF4), often referred to as a smoke generator or DI water Fogger, using DI Water or WFI water
(pharmaceutical water for injection) during a typical 45 minute fog cycle. Water is converted to fog at about 170ml / minute, producing
≈ 1.25 cubic meters of fog / minute and 10-15 visible airflow distance to visualize airflow in pharmaceutical ISO suites, sterile rooms,
barrier isolators, compound pharmacies and semiconductor clean rooms. The CRF4 fogger is designed to provide much more fog
volume to visualize airflow, patterns and turbulence with on/off fog control. The fog output is about 68 degree F, providing a visible fog
vapor composed of microscopic DI water droplets (fog) at a nominal 5μm droplet size. 16 Meg Ohm, pure DI water is the typical water
used to produce the pure fog. Distilled water or Water for Injection (WFI) can also be used. The fogger cost is much lower than
ultrapure foggers, yet offers as much fog as the lower volume, LN2 foggers. The CRF4 fogger uses 35 ultrasonic transducers
converting over 170ml water to fog per minute, providing the highest fog density, and the very best visible airflow of any ultrasonic
fogger produced in the world. A Low Water sensor protects the transducers during operation. The display provides water fill level, and
the touch pad control allows airflow volume to be adjusted, as well as fog volume produced. The CRF4 fogger enclosure is stainless
steel to provide a sturdy external design; while providing water cooling for the internal ultrasonic transducers, and also provides quick,
easy wipe down of the fogger after use. A Handle is provided to lift the fogger and help the user when draining water at completion of
fog task.
A standard power supply is provided at 110VAC, or 220VAC can be ordered. A flexible, transparent, 5 Meter fog hose is provided.
Several useful options are provided, such as Fog Curtain Wand to create a wide fog curtain pattern. A Wireless Remote Control is
available to place the fogger in a closed clean room or sterile room to operate the fogger remotely from the other side of the wall. The
Rolling Carry/Storage Case is useful for parts storage as well as transport. Semiconductor Cleanroom or Pharmaceutical ISO Suite,
Sterile Room or Medical Room use. Y Adaptor allows two fog outputs, while the T adaptor allows for extra wide fog curtain wand. The
LED Light Boost provides superb contrast between the fore ground of fog and the background clean room.
