Are Air Showers Worth The Money?
DO AIR SHOWERS REALLY REDUCE CONTAMINATION? CAN THEY BE COST JUSTIFIED?
The efficacy of air showers in the contamination control process has been a source of debate for several years.
Tests have been conducted which prove the effectiveness of air showers. The tests do show that an air shower does reduce particulate. For the most part, reduction in particulate matter is dependent upon the particle size, the type of garment worn, the cycle time, and directly relates to the air shower design and how it is used and maintained.Air Shower Cheap Price Food Industry Class 100 Clean Room
DOES THE USE OF AN AIR SHOWER JUSTIFY ITS COST?
As a percentage of the total cost of the modern cleanroom, the cost of an air shower is virtually insignificant. In any application where contamination is critically important-such as life science, biomedical, pharmaceutical, parenteral drug, microelectronics, aerospace and precision manufacturing-air showers should be considered essential equipment.
If its use could eliminate contamination of one expensive batch of pharmaceutical chemicals or the rejection of one semiconductor wafer, for example, it is money well spent. Perhaps millions of dollars could be saved.Working Principle Of The Air Shower
In addition, from a psychological point of view, having operating personnel pass through an air shower before entering the work area, reinforces the fact that cleanliness to the operation is essential. This, hopefully, reinforces the concept that protection of the product from personnel is a significant concern.
AN AIR SHOWER CAN BE AN INTEGRAL PART OF THE CONTAMINATION CONTROL PROCESS BECAUSE IT CAN MINIMIZE THE AMOUNT OF CONTAMINANTS BROUGHT INTO THE CLEANROOM FROM THE OUTSIDE:
An air shower is nothing more than a device meant to limit the contamination brought into a controlled area such as a cleanroom. It works by moving air over the worker at a specific high velocity for a specified period of time. In a properly designed air shower, particles are driven off and away from the body and deposited on the upstream side of the HEPA or ULPA filters.
Air Showers have been used effectively in the cleanroom industry for over thirty-five (35) years and have been instrumental in reducing the level of contamination brought into the cleanroom.
Normally positioned between the cleanroom and the outside environment, an air shower is a chamber equipped with a blower unit, interlocking doors, HEPA filters and prefilters, a recirculating air system and multiple air nozzles. Various size nozzles are arranged on the walls and ceiling in a predetermined pattern for the most effective removal of loose particles, dust, or other particulate matter from the garments.Customised All Types Of Food Factory Air Showers
Filtered air is blown through the nozzles directly against the individual standing within the air shower, creating a flapping and shearing effect designed to remove loose contaminants prior to entering a change room, wash room, ante-room or cleanroom. The air is sucked taken from the chamber, stripped of its contaminants through the filtration system, and recycled back to the air shower to continue the cleaning job.
Today’s air shower is equipped with a powerful blower unit, solid state electrical control panels complete with safety monitors and emergency shut-down capabilities that may be activated from both the interior and exterior of the unit.
