Air Showers are self contained chambers installed at entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space. Personnel and materials entering or exiting the controlled environment are "scrubbed" by high velocity ULPA-filtered air jets with velocities of 24-26 m/s (4724-5118 fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.
Esco is a leader in air showers for demanding applications in the micro-electronics, semiconductors, pharmaceutical, spraypainting, lab animal research and food markets. Esco filed its first Air Shower patent in the 1980’s and since then has installed thousands of units in diverse markets worldwide. The present Esco Air Shower is a third-generation product and features a field-programmable microprocessor control that offers the maximum application flexibility of any unit on the market.
Features:
- High velocity shower jets in excess of 24 m/s ensure efficient scrubbing action to remove particulate matter.
- Vertical airflow feature removes residual particulate contamination in chamber.
- Operating modes can be programmed in the field.
- Microprocessor controller supervises all functions.
- Mini-pleated ULPA filtration achieves >99.999% typical efficiency for particle size between 0.1 to 0.3 microns.
- A disposable pre-filter with 85% arrestance extends the life of the main filter.
- An emergency stop button is mounted on both sides of the shower.
- Indicator lights mounted on both sides of the air shower exterior regulate traffic flow in and out of the cleanroom.
- Permanently lubricated direct drive centrifugal blowers are used in conjunction with stainless steel air nozzles.
- Vertical Airflow System continues to purge the chamber of any remaining particulates following the high velocity air cycle.
- Improved direct drive centrifugal blowers:
- Vacuum impregnation for higher motor protection
- Thermal overload protection is wired internally
- C Class F motor
- Dual frequency (50/60 Hz) compatible
