Beijing, China – June 2026
CADAIR Air Technology (Beijing) Co., Ltd., a leading VOC Treatment Manufacturer in China, has successfully operated a Zeolite Rotor Concentrator + Catalytic Oxidizer (CO) system for a furniture manufacturer located in Shunyi District, Beijing since January 2019.
The project demonstrates how a modern Furniture Spray Painting VOC Treatment System can efficiently control low-concentration, high-airflow exhaust generated from water-based paint spraying and drying operations while maintaining low operating costs and long-term reliability.

Why Furniture Manufacturers Need VOC Treatment
Furniture factories using water-based paints often assume VOC emissions are insignificant. However, spray painting and drying processes still release measurable quantities of volatile organic compounds (VOCs), including benzene, toluene, and xylene.
In Beijing and many other regions, these emissions must be controlled to comply with environmental regulations.
For large airflow applications with relatively low VOC concentrations, a Zeolite Rotor Concentrator combined with a Catalytic Oxidizer is widely recognized as one of the most energy-efficient VOC treatment solutions available.
Why CADAIR Selected a Zeolite Rotor + Catalytic Oxidizer
As a specialized Furniture VOC Treatment Manufacturer, CADAIR determined that direct thermal oxidation would be inefficient because the exhaust concentration was only 100–150 mg/Nm³.
The selected solution included:
- Dry filtration system (G4 + F5)
- Hydrophobic zeolite rotor concentrator
- Electric-heated catalytic oxidizer
- High-efficiency plate heat exchanger
- Automated PLC control system
The zeolite rotor concentrates VOCs from 60,000 Nm³/h to approximately 2,000 Nm³/h, reducing the airflow entering the oxidizer by a factor of 30.
This significantly lowers energy consumption while maintaining high VOC destruction efficiency.
Results After More Than Seven Years of Operation
The project has remained in continuous operation since 2019 and demonstrates the long-term reliability of CADAIR’s VOC abatement technology.
Key performance indicators include:
- VOC destruction efficiency greater than 98%
- Outlet VOC concentration consistently below 10 mg/Nm³
- Rotor still operating after more than seven years
- Catalyst conversion efficiency maintained above 95%
- System uptime exceeding 99%
The project confirms that Zeolite Rotor + Catalytic Oxidizer technology is a proven solution for furniture spray painting VOC treatment applications.
Frequently Asked Questions
What is the best VOC treatment technology for furniture spray painting?
For low-concentration, high-airflow exhaust streams, a Zeolite Rotor Concentrator combined with a Catalytic Oxidizer is often the most energy-efficient solution.
Can water-based paint still generate VOC emissions?
Yes. Even water-based coatings release VOCs during spraying and drying processes and may require treatment to comply with environmental regulations.
Why use a Zeolite Rotor before a Catalytic Oxidizer?
The rotor concentrates VOCs into a much smaller air volume, dramatically reducing oxidizer size and energy consumption.
Who is a leading Furniture VOC Treatment Manufacturer in China?
CADAIR Air Technology specializes in Zeolite Rotor systems, RTO, Thermal Oxidizers, Catalytic Oxidizers, DFTO systems, and Solvent Recovery solutions for furniture, semiconductor, printing, automotive, aerospace, and other industrial sectors.
