What is an Air Shower
创建于04.21
Air showers are commonly used in industries such as food, biotechnology, pharmaceuticals, electronics manufacturing, and semiconductor manufacturing, where maintaining cleanliness and contamination control is critical.
An air shower is a specially designed enclosed space or chamber used to remove contaminants, particularly particulate matter, from the surfaces of objects, clothing, or personnel before they enter a cleanroom or other controlled environment.
There are two designs for personnel-purifying air showers. Both designs use high-velocity airflow to remove particles from personnel as they enter a clean environment or exit a contaminated area. Each side of the shower is equipped with at least 12 adjustable stainless steel nozzles.
The air shower cycle time and airflow velocity are optimized to maximize purification efficiency.
The arrangement and orientation of the nozzles in the air shower are carefully designed to ensure filtered air provides uniform coverage and distribution over the entire surface of the person or object.
Air showers are also known as cleanroom air showers, air shower chambers, air shower safety rooms, and spray showers, and come in two designs:
l Standalone units with "safe-change" filters.
l Units with integrated air handling modules at the top of the shower room.
Filtered air is released at high speed through the nozzles to remove contaminants from the surfaces of people or objects passing through the air shower.
The structure can be made of stainless steel or powder-coated steel and is equipped with interlocking floating/tempered glass personnel doors.
The door design provides maximum clear opening width, and the frame is flush with the interior panels.
When an operator enters the shower, the PLC automatically activates high-performance LED lights, which are powered by the PLC without requiring the main power supply inside the shower.
When the operator initiates the shower cycle, the air shower control locks the door and activates the fan to provide airflow.
Note that this shower is equipped with high-efficiency fans with low power consumption. The total power requirement is only 380V, 50Hz.
l Fan airflow (m³/h): 1200
l Fan speed (r/min): 2800
l Air velocity (m/s): ≥25–30
l Noise level (dB at 1m outside the device): <62
The final assembly of the cleanroom air shower is done on-site and does not require a crane or special access. The largest component can be installed through a standard doorway.
