The air shower serves as a critical passage for individuals entering and exiting cleanrooms. It helps reduce contamination caused by people or goods moving between different areas. By using high-purity, filtered air, it effectively removes dust particles that could otherwise enter the clean environment. The system ensures that airborne particles are captured through primary and high-efficiency filters, maintaining a controlled and sterile atmosphere within the cleanroom.

1. Purpose:

Ensure the safety of the air shower and maintain the cleanliness of the cleanroom environment.

2. How to use the air shower:

(1) Personnel entering the cleanroom should remove their outer clothing in the changing room and take off items like watches, phones, and accessories.

(2) Enter the inner dressing area and wear cleanroom garments, including hats, masks, and gloves.

(3) Once inside the air shower chamber, the stainless steel door automatically closes, and the system activates via infrared or heat sensing. The air shower runs for approximately 15 seconds (pre-set at the factory). Note: Do not open both doors simultaneously during operation, as this may damage the electronic lock system. The two chambers are electronically interlocked for safety.

(4) After the air shower cycle completes, exit the chamber and proceed into the cleanroom.

3. Air shower management:

(1) The air shower must be managed by a responsible person who regularly replaces the primary filter every three months.

(2) Replace the high-efficiency filter (with partition) every two years.

(3) Handle the doors gently when opening or closing them.

(4) Avoid touching switches or adjusting the voice prompt system during normal operation.

(5) If the air shower malfunctions, turn off the emergency stop switch immediately and contact maintenance personnel. Under normal conditions, do not use the manual start button.

The Role and Classification of Air Showers

An air shower, also known as a wind shower, clean air shower, purification chamber, or air shower room, is a vital component in maintaining cleanroom standards. Its main function is to remove dust and bacteria from personnel or objects before they enter the clean area. In dynamic environments, humans are the primary source of contamination, so it's essential to blow away any particles on clothing with clean air.

Definition: An air shower is a versatile local purification device used to clean people or cargo before they enter a clean area. High-efficiency filtered air is sprayed from nozzles to remove dust from surfaces.

Classification by blowing method: Top air shower, single-sided, double-sided, triple-sided, double-double, double-triple, multi-side, multi-person, corner, and more.

Classification by material: Stainless steel, steel, color steel, or hybrid materials.

Classification by automation level: Intelligent voice, automatic door, explosion-proof, fast rolling door models.

Classification by use: Human shower, cargo shower, air shower channel, etc.

Main Components of an Air Shower

The air shower/cargo shower series is a flexible purification device installed between non-clean and clean areas. When people or goods pass through, the clean air blown out removes dust and prevents it from entering the clean zone. The front and rear doors are electronically interlocked, acting as air locks to prevent unfiltered air from entering.

1. The air shower consists of components such as the cabinet, stainless steel door, high-efficiency filter, blower, distribution box, and nozzles.

2. The base is made of steel plate, bent and welded, with a white paint finish.

3. The cabinet is constructed from high-quality cold-rolled steel, with electrostatically sprayed surface for durability and aesthetics. The inner bottom is made of stainless steel for easy cleaning.

4. Customization is available for materials and dimensions based on customer needs.

The role of the air shower is to serve as a necessary purification equipment for personnel entering the cleanroom. With powerful clean air, it sprays all directions through rotating nozzles, removing dust, hair, and other debris from clothing. This reduces pollution from movement in and out of the cleanroom. The interlocked doors also act as an air lock to prevent external contaminants from entering, ensuring a high-standard clean environment for production of quality products.

Chapter Four

What Is the Purpose of the Air Shower?

The air shower is a necessary passage for people or goods to enter and exit the cleanroom, functioning as a sealed airlock chamber. It uses high-efficiency filtered air to spray from multiple directions, removing dust and particles from surfaces. The air is then filtered again through primary and high-efficiency filters before being recirculated. To achieve optimal performance, the air shower can be designed with a wind speed exceeding 25 m/s. It offers modular assembly options, allowing customization to fit various cleanroom sizes and needs.

Common Knowledge About Air Showers

1. Introduction

An air shower is a highly versatile purification equipment used to clean people or cargo before entering a clean area. High-efficiency filtered air is sprayed through nozzles to remove dust and debris from surfaces.

2. Other Names of the Air Shower

Also known as wind shower, clean air shower, purifying air shower, air shower room, blowing room, air shower door, dust removal room, shower room, air shower corridor, and air shower machine.

3. Classification of Air Showers

By blowing method: Top, single, double, triple, double-double, double-triple, multi-side, multi-person, corner, etc.

By material: Stainless steel, steel, color steel, or hybrid structures.

By automation level: Intelligent voice, automatic door, explosion-proof, fast rolling door types.

By usage: Human shower, cargo shower, air shower channel, etc.

4. Structure Description

The air shower consists of a cabinet, stainless steel door (or painted/colored steel door), coarse filter, high-efficiency filter, fan, static pressure box, nozzle, interlock controller, operation panel, and induction device.

5. Role of the Air Shower

The air shower is essential for personnel entering a cleanroom. It uses strong, purified air from rotating nozzles to remove dust, hair, and other particles from clothing, reducing contamination risks. The interlocked doors function as an air lock, preventing unclean air from entering the clean area. This helps maintain strict dust-free standards, ensuring the production of high-quality products in a controlled environment.
