CRF4 Portable Fogger supports ISO 14644-3, USP797, Federal Standards 209E, ISO 14644-1 and 14644-2 airflow guidelines Compare Foggers at hhttps://appliedphysicsusa.com/cleanroom-fogger-comparison/ Request Quote at https://appliedphysicsusa.com/contact-us/ The CRF4 is a portable clean room fogger that can use deionized (DI) water, sterile water or water for injection (WFI) to generate 1.25 cubic meters of pure fog per minute at 187 ml fog density per minute to provide from 10 to 15 feet visible fog distance. If you are comparing another fogger to the CRF4, how much fog volume and fog density does the other fog generator produce? Do you need airflow visualization in barrier isolaters, RABs or clean rooms? The CRF4 is ideal to visualize airflow in pressurized clean areas, such as glove boxes and barrier isolators. Becuase the CRF4 can be operated by remote control from outside a clean area, and becuase the CRF4 is relatively compact in size, it can be inserted inside or beside a glove box or isolator, allowing the fog volume and air flow velocity to be adjusted remotely. If space allows the CRF4 to be inserted inside the clean area, insert the CRF4 inside the clean area. If space is not available in the glove box or isolator, construct a pressurized, holding box next to the glove box or isolator. After placing the CRF4 inside the pressurized box, ensure pressure is maintained after closing. Cut two 80mm holes between the clean area and box, allowing air to be pulled in from the box and allowing fog to be directed into the top of the glove box or isolator. Connect the 80mm fog hose to the 80mm fog inlet of the glove box or isolator; and operate the CRF4 from outside using wireless remote control. The CRF4 is designed to tune the fog output to your airflow dynamics, providing up to 10 to 15 feet visible airflow. The CRF4 would be used in smoke studies of semiconductor clean rooms, ISO suites, sterile rooms, bio-safety cabinets, RABs and medical rooms. Airflow guidelines ISO 14644-3, USP 797, Federal Standards 209E and its replacement ISO Standard 14644-1 and 14644-2 are supported for airflow recovery tests. https://appliedphysicsusa.com/product/crf4-cleanroom-fogger/ Applied Physics provides clean room foggers to visualize airflow turbulence, patterns, velocity, and dead zones during smoke studies. The CRF4 produces almost as much pure fog as ultrapure foggers, which use LN2 and DI water. It includes adjustable airflow, adjustable fog volume and wireless remote control, which is not found on other ultrasonic foggers. The advantage of the CRF4 is the fog density generated at 187 ml per minute, which is higher than any other smoke machines in the world. When you look at the different smoke generators available, it is important to determine how much fog volume the fogger produces? How much fog density is generates? And the typical visual distance of the fog in typical sterile room operation. All foggers provided some form of direct control of the fog, but does your smoke generator offer wireless remote control of the fog operation, so that it can be used inside a closed area. CRF4 uses 35 ultrasonic piezo devices to generate a pure fog of 1.25 cubic meters / minute with 187 ml of fog density for 10-15 feet of visible fog. The CRF4 can be turned on or off at will, and refilled with DI Water, Sterile Water or WFI Water as needed. The fog volume can be adjusted higher to 1.25 cubic meters fog / minute or lowered to 0.5 cubic meters fog per minute, and the airflow can be adjusted from 10% to 100% airflow to fit your clean room air flow dynamics. The CRF4 does not use LN2, yet produces as much fog as the smaller LN2 foggers and the fog output can be adjusted; for a lower cost than any LN2 ultrapure fogger. The only maintenance is to drain water and to air dry the water cavity immediately after each fog study. In order to create larger volumes of fog, 35 ultrasonic devices are used, which vibrate at high frequencies, generating high volumes of vapor droplets at a diameter of 5 to 8 microns. The fog vapor is suspended just above the water line, and then captured by the internal airflow and directed outside the fogger into the clean room or clean area. Attach a Y Adaptor to direct two air flows upwards into the clean room. Or attach a 5 meter fog hose to direct fog as needed. The Y Adaptor can also be plugged into the tip of the 5 meter fog hose. If you prefer a 50mm fog hose output, a dual kit is available and provides two, 5 meter x 50mm hoses, each with a 0.6 meter fog wand attached, is available.

Or touch the down arrow to decrease the airflow. If fog volume needs to increase or decrease, go into mode control and adjust from 25% fog volume to 100% fog volume during operation.
