Air Shower is an enclosed entry chamber where personnel pass through high-velocity filtered air before entering a cleanroom or lab. The air jets run at 20 m/s or higher, about 66 ft/s, and dislodge dust and loose particles from clothing. HEPA or ULPA filters clean the air before the air reaches the nozzles, and the nozzle layout is adjustable. Cycle time is adjustable. Photoelectric sensors are listed, and interlocking doors keep both doors from opening together. Emergency stop buttons and automatic door locking are also listed. Tunnel layouts are also used. Pharmaceutical, biotech, semiconductor, food, aerospace and hospital facilities use air showers at cleanroom entries.
Frequently Asked Questions
1 What is an Air Shower?
An Air Shower is a cleanroom device designed to remove loose particles and other pollutants thereby maintaining a contamination-free environment.
2 How does an Air Shower work?
It works by utilizing high-velocity air jets to blow away dust particles & other contaminants from the surface.
3 What kind of air filter is used in Air Shower?
It utilizes High-Efficiency Particulate Air (HEPA) filter to trap fine particles and ensures that the air used in shower is free of contaminants.
4 Is Air Shower safe to use?
It is engineered with safety features such as emergency stop buttons and automatic door locking mechanisms to prevent accidents.
5 Can Air Shower remove all types of contaminants?
It is effective in removing loose particles, dust and other airborne contaminants.
6 What kind of maintenance does the Air Shower require?
Regular maintenance includes cleaning of filters, checking for airflow blockages and ensuring proper functioning of air jets.
Selection Guide for Air Shower
Air Shower is used to remove loose particles from personnel or equipment before entering cleanroom environments. When selecting an Air Shower, consider key factors like the type (personnel, material, or tunnel), traffic volume, and entry/exit configuration (straight-through, L-shaped, etc.). Make sure the size fits your users or equipment, and choose durable materials like stainless steel or powder-coated steel. Look for HEPA or ULPA filters with high-efficiency blowers delivering air at 20–25 m/s through adjustable nozzles. A PLC or microprocessor-based control system with interlocked doors enhances safety and performance. Check for adjustable cycle time, suitable power supply, low noise levels, and compliance with cleanroom standards (ISO, GMP). Optional features, such as UV lights, access control, or voice prompts, can further increase functionality.
Understanding Air Shower: Purpose, Process, and Benefits
Air Shower is a self-contained chamber that uses high-velocity, HEPA- or ULPA-filtered air jets to remove dust, particles, and microbial contaminants from personnel or equipment before they enter a cleanroom. Installed at cleanroom entry points, it serves as a controlled environment between a non-sterile area and a sterile zone, helping maintain the integrity of the cleanroom environment.
Our Air Shower works typically at speeds of 20–30 m/s—are activated to dislodge particles from clothing or surfaces and are engineered with advanced features that enhance both contamination control and user experience. The system typically consists of:
Air Shower is essential in industries where product sterilityand contamination controlare critical. In pharmaceutical manufacturing, they ensure that personnel entering cleanrooms do not bring in contaminants that could compromise sterile drug production. Within the biotechnology and life sciences sectors, Air Shower protect sensitive biological experiments and cell cultures from environmental interference. The semiconductor and electronics industry relies on it prevent static and particle contamination that could damage microchips or delicate components. In food and beverage processing, it helps in maintaining hygiene by reducing the risk of airborne contamination during production. The aerospace and defence industries use this system to guarantee a particulate-free environment for the assembly of high-precision instruments. Lastly, in hospitals and medical facilities, our Air Shower is deployed in isolation rooms and surgical areas to control microbial loads and ensure patient safety.
