More

MayAir Technology (China) Co., Ltd. is a subsidiary of MayAir Group, and its registered brand is "MayAir". MayAir is committed to promoting the development of the air purification industry and improving the global air quality.

Since its establishment in 2001, MayAir, which is based in China, has used industrial-grade ultra-clean technology in commercial and public spaces.

From air intake to exhaust, from filter unit package to complete equipment to system integration, we continue to innovate to meet the growing demand for clean air products. The main business of MayAir is in air purification products. It also focuses on research and development, production, and sales of atmospheric environment treatment products.

The products are mainly used in cleanroom air purification. Due to the demand for air purification in the public medical and healthcare industry after the outbreak of the COVID-19 epidemic, MayAir vigorously promotes research and development, production, and sales of medical air purification equipment. MayAir gradually develops and accumulates technologies in atmospheric environment treatment and actively develops the market for industrial dust removal, oil mist removal, and VOCs treatment.

MayAir focuses on semiconductors, biopharmaceuticals, public health care, industrial dust removal, VOCs treatment markets,etc. Its products comprising fan filter units, high-efficiency, low-medium efficiency, chemical, electrostatic, and air purifiers are used for dust removal, oil mist removal, and VOCs treatment.

Its products can be used for cleanroom air purification, indoor air quality optimisation, and atmospheric pollution emission control.

The subdivision of downstream applications is mainly for the semiconductors, biopharmaceutical and food industry. It is also used in medical institutions, large commercial buildings, public places, home environments, industrial dust removal, VOCs treatment, etc.

MayAir has set up seven domestic production bases and two overseas production base. They are the Nanjing production base(three), Zhongshan production base, Chengdu production base, Tianjin production base and Wuxi production base. Meanwhile, its oversea production base is located in Malaysia and Canada. The total production plant area exceeds 50,000 square meters. The company is now one of the largest suppliers of the air purification industry in the country.

PRODUCT FEATURES

 

  • Modular design for enhanced flexibility
  • Professionally laser-welded construction
  • Frame available in coated steel or stainless steel
  • Equipped with PAO injection and sampling ports, supporting filter scanning
  • 100% factory tested; on-site testing services available
  • Optional accessories include polypropylene replacement bags, pressure gauges, biosafety dampers, and pre-filters

 

STRUCTURAL FEATURES

 

  • Modular Configuration for Flexible Assembly Based on Airflow and Installation SpaceThe BIBO system consists of multiple filter unit modules, assembled according to airflow requirements. Each module features a standardized size and structure. Core components include pre-filters, HEPA filters, service doors, change-out bags, scanning detection devices, and biosafety shut-off valves. Auxiliary elements such as pressure gauges, PAO aerosol dispersion units, and quick-connect ports ensure complete system functionality. These modules can be arranged flexibly to accommodate site constraints.
  • Versatile Biosafety Shut-off Valve OptionsThe BIBO system connects to the exhaust duct via biosafety shut-off valves, available in both rectangular and circular configurations to match customer ductwork requirements.
  • Precision Welding for Structural ReliabilityEach BIBO module is fabricated with CNC cutting, CNC lathe processing, and full-seam welding. Specially designed clamping mechanisms secure the filters in place, ensuring optimal sealing performance and structural strength.

 

APPLICATIONS

 

The BIBO system is widely used in high-containment or hazardous exhaust scenarios, including:
 
  • Chemical and biological (CB) protection
  • Chemical, biological, and radiological (CBR) defense
  • Nuclear, biological, and chemical (NBC) containment
  • Hospital isolation rooms and pharmaceutical equipment
  • Microelectronics production and food processing facilities
  • Biological research and genetic engineering laboratories
  • Industrial emission control and chemical processing systems
  • Animal disease research labs and radioactive isotope handling
  • Nuclear power plants, D.O.E. facilities, and military bases
 
The BIBO containment system ensures pollutants are not released during operation. All filter installations, replacements, and testing are conducted within a sealed change-out bag, fully isolating the filter unit from personnel and the surrounding environment, protecting both workers and public health.
 

PRODUCT TESTING

 

In accordance with JG/T497-2016, GB19489-2008, and GB50346-2011 standards, every MayAir BIBO system undergoes comprehensive factory testing to ensure compliance with required safety protection levels. These tests include pressure resistance, enclosure leak tests, PAO scanning, and more. Each unit is delivered with accompanying BIBO and filter test reports.
Optional features such as manual or automatic PAO scanning, biosafety-sealed valves, and fumigation ports enable on-site leak detection and ventilation system decontamination based on customer requirements. MayAir BIBO systems have successfully passed P3/P4 biosafety compliance, performance testing, and disinfection validation, with inspection reports certified by accredited third-party institutions.
