Fully Automatically Cleanroom Equipment Air Shower for Clean room Enterance

Air Showers have become an integral component of the modern cleanroom because their benefits more than pay for the small amount of space they occupy. With their interlocking doors and automatic cycling, air shower systems act as traffic guards, controlling passage into and out of the cleanroom.

The following is a list of cleanroom air showers offered by CleanAir Solutions:

E-Series Economy Air Shower

S-Series Standard Air Shower

V-Series VLF Air Shower (provide vertical flow at 100FPM)

L-Series Low-Height Air Shower

Sample Configurations for Air Shower Systems

Air Shower Design Specifications

Air Showers clean micro particles off personnel and equipment as they enter or exit a cleanroom. Upon exit, cleanrooms are envelope sealed when the unit automatically switches into an airlock. They can also be used to remove hazardous contaminate from personnel when exiting facilities

Not to be ignored is the psychological impact a cleanroom air shower creates: Personnel are reminded with every passage that they are entering a controlled environment, while prospective clients are assured of your quality control standards when they enter your facility.

Personnel Entry Clean Air Shower

Designed to remove surface contamination from personnel entering a cleanroom. The air shower is automatically actuated upon entry-releasing a bath of clean air from the side walls and ceiling. After a timed duration, the shower shuts off and allows exit. The HEPA filtered air is 99.99% efficient on .3 microns, and is recirculated for containment. Available in two configurations: Model S (straight-thru, illustrated), and model L (providing right angle passage). Parts Pass Thru Air Showers for Cleanrooms also available.

Air Shower Specifications

Filter: Twelve inch HEPA (High Efficiency Particulate Air) type, PSL challenged, zero probed. Minimum efficiency of 99.99% at .3 microns.

Pre-filter: One inch bonded polyfiber media minimizes surface-loading. Low wall return to HEPA filter atop unit. Quick release grille.

Airflow: Air velocity at nozzle is minimum 6000fpm.

What are the features required in a proper air shower design?

Let us not lose site of the fact that an air shower, if incorporated, should be part of an engineered” entry system” and is not designed as a watch dog to compensate for poor protocol, but as a tool to control contamination levels within the cleanroom, just as the garment itself should be considered. At all times we must remember, the garment is the tool within the cleanroom which comes in closest contact, and in contact most often, to the product. Features which the authors believe should be part of a properly designed air shower are:

Filtration which is the guiding premise of cleanroom design, should not be overlooked in air shower design. It should not be assumed that air showers recirculate clean air, therefore they do not require filtration themselves. Air showers, as cleanrooms, should follow the basic concept of filtering and moving air, to both remove contamination from the garment and extracting the removed contamination from the environment. The authors suggest the use of ulpa filtration 99.9995 % efficient @ .12 micron.

Airflow should as a minimum range between 6000 to 7500 feet per minute (fpm), or the equivalent to 60 to 90 miles per hour, to insure turbulent enough air to dislodge surface particulate from a clean room garment. There have been studies done which proclaim the advantages of still higher velocities, that of up to 12,000 fpm, and or lower velocity, as low as 90 to 150 fpm which approach laminar airflow design levels. As neither of these alternative tests have been documented, the authors could not evaluate their effectiveness; however, it is their opinion that airflow upwards of 12,000 fpm may be of substantial speed to actually impregnate particles on cleanroom garments and low velocity air showers (90 to 150 fpm) although effective in preventing the infiltration of particulate into the cleanroom during the entering process (acting as more as an air lock than an air shower) will not dislodge particulate which has settled on the garment. It should be noted that the 6000 to 7500 fpm rate is suggested as part of a design which incorporates multiple points of impact and is widely accepted by air shower manufacturers.

Cycle time is considered to be the most critical aspect of air shower effectiveness. Studies have suggested that a minimum of 20 seconds is required to properly remove contamination from garments. More intriguingly, our own studies tend to indicate garments in the second and third day of use require longer air shower cycle times to remove contamination. These findings suggest a “smart” air shower design utilizing a real time clock and calendar to increase cycle time during the later stages of garment use, or better still an air shower design utilizing particle count technology to control exit, would most probably produce a benefit which far outweighs the additional cost.
