Dongguan Baihong Purification Equipment Co., Ltd. was established in 2011 in Dalang, Dongguan, Guangdong, China. The company specializes in the research, development, manufacturing, and supply of cleanroom and air purification equipment.
Its main products include air showers, cargo air showers, FFU fan filter units, pass boxes, clean benches, clean booths, and other cleanroom equipment. These products are used in industries such as electronics manufacturing, new energy batteries, food processing, pharmaceuticals, and optoelectronics.
Over more than a decade of development, Baihong Purification has gradually expanded from a cleanroom equipment manufacturer focused on air shower production into a supplier with capabilities covering product development, sheet metal processing, equipment assembly, quality inspection, customization, and overseas supply.
1. More Than 10 Years of Development in Cleanroom Equipment Manufacturing
Baihong Purification was founded in 2011 and initially focused on the manufacturing of air showers and related cleanroom equipment.
As customer requirements and cleanroom applications evolved, the company gradually expanded its product range to include cargo air showers, FFU fan filter units, pass boxes, clean benches, clean booths, and other cleanroom products.
These products are used in different controlled-environment applications, including electronics factories, battery manufacturing facilities, food processing plants, pharmaceutical production areas, and optoelectronic manufacturing.
Since 2016, Baihong Purification has continued to upgrade its manufacturing capabilities by introducing automated and precision processing equipment, including laser cutting systems. These upgrades have helped improve sheet metal processing efficiency and production consistency.
2021: Manufacturing and Facility Upgrade
In 2021, the company completed a RMB 2.88 million capital increase and launched a comprehensive factory upgrade project.
The project included:
- Renovation and upgrading of 24 employee dormitory rooms.
- Expansion of office facilities, including a general office area, business reception room, and R&D workspace.
- Installation of water-cooled air-conditioning systems in the production workshop.
- Introduction of laser cutting, laser welding, and CNC bending equipment.
The investment was aimed at improving both the working environment and manufacturing infrastructure, while providing stronger production support for standard and customized cleanroom equipment.
2. Integrated Manufacturing Process for Cleanroom Equipment
As a cleanroom equipment manufacturer in Dongguan, Baihong Purification has developed an in-house manufacturing process covering several key production stages.
The main manufacturing processes include:
- Laser cutting
- CNC bending
- Laser welding
- Sheet metal fabrication
- Equipment assembly
- Finished-product inspection
This manufacturing structure allows the company to handle different equipment configurations according to project requirements.
For example, air shower specifications can be customized according to the available cleanroom space, personnel flow, material requirements, door configuration, and application environment.
Depending on the application, Baihong Purification can supply:
- Single-person air showers
- Double-person air showers
- Multi-person air showers
- Cargo air showers
- Automatic air showers
- Customized air shower systems
Material options and structural configurations can also be adjusted according to project requirements, including stainless steel construction and different equipment dimensions.
For international customers, customization can be combined with export-oriented documentation and equipment configuration requirements.
3. Product Development, Patents and Quality Management
Technical development has been an important part of Baihong Purification’s long-term growth.
The company currently holds 24 granted patents and 11 registered trademarks. It also obtained recognition as a National High-Tech Enterprise in 2022, with certificate number GR202244002108.
The company has also obtained CE certification for applicable products and has developed experience in serving overseas customers.
For international projects, equipment supply may involve not only the physical product but also technical documentation, product specifications, operating instructions, and other project-related materials.
This provides a foundation for Baihong Purification to serve customers outside China who require cleanroom equipment for different manufacturing environments.
4. Serving Different Cleanroom Applications
Cleanroom equipment requirements vary significantly between industries.
In electronics and semiconductor-related manufacturing, equipment may need to be integrated with personnel and material flows in a controlled production environment.
In battery and new energy manufacturing, cargo air showers and customized equipment may be required for material transfer areas.
Food processing facilities may focus on personnel hygiene control and contamination reduction, while pharmaceutical and medical-related applications can involve more specific cleanroom configurations and operating requirements.
Baihong Purification therefore focuses on supplying equipment according to the actual application rather than using a single standard configuration for every project.
The company can provide both standard cleanroom equipment and non-standard customized equipment, depending on the customer’s layout, dimensions, material requirements, and operating conditions.
5. From Dongguan Manufacturing to International Equipment Supply
After more than ten years in the cleanroom equipment industry, Baihong Purification continues to focus on manufacturing as the foundation of its business.
The company’s development has progressed from individual equipment production toward a more complete manufacturing and supply system covering:
Product Development → Sheet Metal Processing → Welding & Fabrication → Assembly → Inspection → Equipment Supply
This structure allows Baihong Purification to respond to different requirements for air showers, cargo air showers, FFU fan filter units, pass boxes, clean benches, and other cleanroom products.
Looking ahead, the company plans to continue investing in manufacturing automation, digital management, product development, and quality control.
With its manufacturing base in Dongguan, Baihong Purification aims to provide reliable cleanroom equipment and customized solutions for customers in China and overseas markets.
