Air Shower also provides and effective air lock system which restricts the clean area in the event of door opening.
Air shower consists of cabinet, stainless steel door (cold steel), pre-filter, HEPA filter, pan, plenum chamber, nozzle, interlocking control panel, operation panel, sensing equipment, etc.
Cold steel is used for the air shower’s cabinet, and stainless steel is used for the bottom. As to different customer’s requirement, air showers with different materials or sizes can be designed and supplied.
Principle of Working
As the person enters the shower room, the start switch activates the pre-selected shower time to produce flood of high velocity low pressure clean air through the fourteen concentric nozzles which washes away dust particles and other contamination adhere to the body and the same is swept away through the filtration media provided at the floor level exhaust of the equipment. The electronic timer also activates magnetic locking system of the unit which is synchronized with the Air Shower timing for entry and exit. High efficiency Micro-filtration medias are used for cleaning & recycling of the clean air in the Air Shower upto efficiency to produce Class 100 or Class 10000 clean air.
