Both the doors of our material handling Tower flow air showers are interlocked and magnetically operated. They are permanently energized and open instantly when the open door push is pressed. Once the user enters the air shower cubicle, he/she can start the shower cycle from the inside. The shower cycle is programmable and can be set as per the requirements of the industry. Both the doors of the unit remain locked till the shower cycle continues, to prevent the entry of external contaminants while the air shower is operational. Once the Tower flow air shower cycle is completed, the personnel can exit through the exit door. The one-way mode of operation allows the user to enter the air shower cubicle, but he/she cannot exit through the entrance door, therefore controlling the traffic patterns into and out of the controlled environment chamber. Moreover, the pre-purge function of our modular air showers allows the unit to self-clean in a power-on mode. The pre-purge time is also programmable and can be set between **3 minutes. Air shower principle is based on subjecting the personnel through adequate velocity of clean air coming through a pre filter assembly.

 

The air present in the air shower cubicle is continuously circulated through the filter assembly, comprising of pre-filters and HEPA filters. The filter assembly physically entraps the contaminating particles and removes them from the air circulation. The efficient fans and blowers blow the filtered air into the air shower cubicle through adjustable nozzles at appropriate face velocities. The turbulent air streams produce enough shearing effect to loosen the dust particles and other particulate matters from the external surfaces, causing their wash down with the air stream. The air shower cubicle is maintained at a slightly higher pressure as compared to the outside to prevent the contaminating particles from entering the cubicle when the unit is at rest.  Air Shower specifications are in accordance with the US Federal Standards.
