In what fields are irregular-shaped air showers generally used

As a customized product of the conventional air shower, the irregular-shaped air shower has a special structural design that can adapt to various complex scenarios. Its main application fields and scenarios are as follows:
I. Electronic Semiconductor Industry
Core scene:
Chip manufacturing workshop (such as photolithography machine area, wafer packaging line)
The contamination of particulate matter at the 0.1μm level needs to be controlled. The irregular-shaped air shower can be designed as L-shaped or U-shaped according to the layout of the clean area to avoid the interference of right-angle corners on the airflow and ensure the cleanliness level of ISO 5 (Class 100).
Precision electronic component assembly line
For long and narrow passages or embedded wall structures, custom-made ultra-thin cross-flow fan air shower rooms are designed to reduce space occupation while meeting the air shower requirement of an outlet wind speed of ≥25m/s.
Ii. Biopharmaceuticals and medical fields
Typical applications:
GMP sterile workshop (vaccine production, injection filling line) :
The 316L stainless steel material irregular-shaped air shower is adopted, combined with the arc design at the corner (to avoid the breeding of microorganisms in dead corners), and is linked with the transfer window and buffer room, meeting the FDA/GMP certification requirements.
Biosafety Laboratory (BSL-3/4) :
The air shower is designed as a dual-channel interlocking structure, with ultraviolet sterilization lamps and high-efficiency filters installed inside. The irregular-shaped pipes can be integrated with a negative-pressure exhaust system to prevent the leakage of bioaerosols.
Iii. Food and Baking Industry
Scene requirements:
High-temperature environment in the baking workshop
Customized high-temperature resistant irregular-shaped air shower (with a temperature resistance of ≥80℃), the fan is equipped with a heat dissipation device, and the shell is made of food-grade 304 stainless steel to prevent grease adhesion and bacterial growth.
Frozen food processing line
For low-temperature environments (-18℃), the structure of the air shower should be designed to prevent condensation. Special-shaped pipes can be arranged at an Angle to prevent frosting and clogging of the filter.
Iv. Aerospace and Precision Manufacturing
Special applications:
Aeroengine blade processing workshop
The irregular-shaped air shower, in combination with a three-stage filtration system (primary efficiency + medium efficiency + high efficiency), has a wind pressure of ≥600Pa, ensuring that the high-pressure airflow blows off the metal processing debris and meets the ISO 7-level cleanliness requirements.
Satellite Component Assembly Room
The modular irregular-shaped air shower is adopted, which can be disassembled and transported to the clean workshop for on-site assembly. The internal airflow simulates the microgravity environment of space, avoiding the deposition of particulate matter.
V. Chemical Engineering and Explosion-proof Fields
Security requirement scenarios:
Flammable and explosive workshops (such as lithium battery electrolyte preparation areas) :
The fan of the special-shaped air shower room needs to pass the Ex d IIC T6 explosion-proof certification. The pipeline adopts an anti-static grounding design to avoid explosion caused by static sparks, and at the same time adapts to the complex explosion-proof wall layout in the workshop.
Corrosive gas environment (such as electroplating workshops) :
The shell is made of PVC or fiberglass-reinforced plastic. The special-shaped pipes are lined with anti-corrosion coatings. The fan impeller is made of fluoroplastic to resist acid mist corrosion.
Vi. New Energy and Energy Storage Industry
Emerging applications:
Lithium battery cell assembly workshop
Customized special-shaped air shower for dust-free workshops, combined with dehumidification function (humidity ≤ 20%RH), to prevent moisture in the air from reacting with lithium metal. The structure of the air shower can be embedded in explosion-proof walls to save space in the clean area.
Photovoltaic module clean workshop
In response to the high-temperature environment of the lamination process, the air shower is designed as a dual-channel structure, with personnel and materials being blown and sprayed separately. The irregular-shaped pipes can be integrated with an exhaust gas treatment device to filter out the organic substances volatilized by the EVA film.
Vii. Other special scenarios
Nuclear power plant maintenance passage
The irregular-shaped air shower must meet the radiation protection requirements. The outer shell is equipped with a lead plate shielding layer, and the pipeline is designed as a labyrinth structure to prevent the spread of radioactive dust.
Cultural Relics Restoration Laboratory
The airflow velocity in the air shower is controlled at 15-18m/s (to prevent strong winds from damaging cultural relics). The irregular structure can be adapted to arched roofs or irregular walls. The interior is equipped with silent fans to reduce the interference of noise during the precise restoration work.
Apply the core logic of selection.
The essence of the field application of irregular-shaped air showers is the combination of "structural adaptability" and "functional customization" :
Space adaptation: Addressing scenarios where conventional air showers cannot be installed, such as L-shaped, U-shaped, and multi-story building passageways;
Environmental adaptation: Enhance materials and performance for special environments such as high temperature, low temperature, explosion-proof, and anti-corrosion.
Process adaptation: In line with the cleanliness and airflow requirements of precision processes such as semiconductor lithography and biological fermentation.
From the application cases in the above fields, it can be seen that the irregular-shaped air shower has extended from the traditional clean field to more industries with high customization demands. The core of its design is to balance "space limitations" and "purification efficiency" in complex scenarios.
