When a cleanroom project requires hundreds of FFU (Fan Filter Unit) systems, the key challenge is not only manufacturing capacity, but also production consistency, quality control, and reliable delivery.
Baihong Purification recently completed a bulk cleanroom equipment supply project for an electronics PCB manufacturing cleanroom project in Shanghai, China.
The project included 279 FFU fan filter units, along with stainless steel air showers, pass boxes, and PVC rapid doors. All equipment was manufactured, inspected, and prepared for shipment at Baihong’s production facility in Dongguan.
Project Overview
Project Type: Bulk cleanroom equipment supply project
Application: Electronics PCB manufacturing cleanroom
Supplier: Baihong Purification
Manufacturing Location: Dongguan, China
Delivery Location: Shanghai, China
Main equipment supplied:
| Equipment | Specification | Quantity |
|---|---|---|
| FFU Fan Filter Unit | 1175 × 575 × 320 mm housing; 1170 × 570 × 69 mm filter | 276 units |
| FFU Fan Filter Unit | 575 × 575 × 320 mm housing; 570 × 570 × 69 mm filter | 3 units |
| Double-Person Double-Blow Air Shower | SUS304 stainless steel structure | 3 units |
| Pass Box | SUS304 stainless steel structure | 6 units |
| PVC Rapid Rolling Door | Cleanroom supporting equipment | 13 units |
The complete order was manufactured and delivered as a coordinated equipment package rather than a single-product shipment.
Manufacturing Process for Bulk FFU Production
For large-volume FFU orders, production consistency is essential.
Each FFU requires multiple manufacturing steps, including:
- Sheet metal cutting;
- CNC bending;
- Fan and electrical component assembly;
- Filter matching;
- Final inspection before shipment.
At Baihong Purification, FFU housings are manufactured using a riveting process supported by automatic rivet feeding equipment.
This production method helps improve assembly efficiency and maintain consistent workmanship during batch manufacturing. The riveted structure also provides convenience for future maintenance or equipment relocation.
Coordinated Production of Multiple Cleanroom Equipment
This Shanghai project involved more than FFU units.
Along with 279 FFUs, Baihong also supplied air showers, pass boxes, and PVC rapid doors.
Different cleanroom equipment requires different manufacturing processes:
- FFU production focuses on airflow components, housing structure, and filter installation;
- Air shower production involves stainless steel fabrication, nozzle arrangement, and electrical assembly;
- Pass box production includes structural fabrication and interlock system installation;
- Rapid doors require size matching and operation testing.
Managing multiple equipment categories within one project requires effective production planning, material preparation, and quality inspection procedures.
Quality Control from Manufacturing to Shipment
For cleanroom equipment projects, production completion is only one part of delivery.
Before shipment, all equipment must go through:
- Quantity verification;
- Appearance inspection;
- Packaging protection;
- Shipment preparation.
For this project, all equipment was inspected and packaged at Baihong’s Dongguan factory before being transported to the Shanghai project site.
A reliable cleanroom equipment supplier should not only provide individual products, but also have the ability to coordinate manufacturing, inspection, and delivery for complete equipment packages.
