Mayair Technology Supports Historic Maiden Flight of CZ-10B Carrier Rocket

A Milestone for China’s Reusable Commercial Spaceflight

On July 10, the Long March 10B (CZ-10B) carrier rocket successfully completed its maiden launch from the Hainan Commercial Space Launch Site, delivering payloads into preset orbit and achieving net-capture controlled recovery of its first stage at sea.

As China’s flagship reusable heavy-lift liquid rocket, this mission marks a major step toward low-cost, high-capacity and reusable commercial space operations. Behind this national engineering breakthrough, Mayair’s air purification solutions have been deployed across rocket R&D and final assembly clean environments, providing aerospace-grade air quality safeguards for the manufacturing of this critical equipment.

Project At a Glance

• Mission: Maiden flight of CZ-10B reusable carrier rocket, with verified sea-based first-stage recovery
• Mayair Scope: Full-spectrum air filtration for AHU fresh air systems in R&D and final assembly facilities
• Technical Solution: Progressive 3-stage filtration (pre / medium / high efficiency) for clean environment protection
• Industry Significance: Validates Mayair’s high-end clean technology for national-level aerospace engineering

Mission Recap: CZ-10B Makes Breakthrough in Reusable Rocket Technology

Developed by the China Academy of Launch Vehicle Technology, the CZ-10B adopts a 5-meter-diameter two-stage tandem configuration, with a total length of approximately 63 meters and a takeoff thrust of 890 tons.

• First stage: Powered by LOX/kerosene propellant, designed for recovery and reuse
• Second stage: Equipped with new-generation LOX/methane engines
• Payload capacity: 16 tons to LEO in reusable configuration
• Application scenarios: LEO satellite internet constellations, commercial satellite launches, deep space exploration

The successful sea-based net-capture recovery technology demonstrated in this mission significantly reduces the overall cost of space launches, accelerates the iteration of China’s rocket recovery technology, and lays a solid technical foundation for future manned lunar landing and deep space exploration programs.

How Mayair Powers Precision Aerospace Manufacturing

Precision aerospace production imposes extreme requirements on environmental cleanliness — even micron-sized dust particles can affect the performance and reliability of precision components. To meet these strict standards, Mayair provided a complete graded filtration package for the project’s AHU fresh air systems.

Progressive 3-Stage Filtration System

Filter media of different efficiency grades are arranged sequentially inside air handling units, creating a layered protection system:

1. Pre-filters: Capture large particulate matter at the air intake, extending the service life of downstream filters
2. Medium-efficiency filters: Intercept fine dust particles to reduce load on high-end filter media
3. High-efficiency filters: Deliver terminal purification to meet the strict cleanliness requirements of aerospace manufacturing

This step-by-step design not only ensures stable and consistent clean air performance, but also slows the wear of high-value filter elements, lowers long-term operation costs, and supports uninterrupted stable operation of the entire fresh air system.

From semiconductor ultra-clean workshops to aerospace final assembly plants, Mayair develops and manufactures all filtration products to industrial-grade reliability standards. This CZ-10B project marks another successful deployment of Mayair’s high-end clean technology in national key projects, following proven track records in semiconductors, life sciences and lithium battery new energy sectors.

Shared Craftsmanship: Chinese Manufacturing Joins Hands for Deep Space Exploration

The pursuit of excellence and continuous exploration defines the spirit of China’s aerospace industry. The same dedication to technical refinement and long-term industry focus drives Mayair’s development.

As an air purification enterprise listed on the STAR Market, Mayair holds hundreds of independent intellectual property rights. Its core filter media and clean air systems are fully independently developed and mass-produced domestically, serving high-end precision manufacturing chains worldwide.

This partnership with the CZ-10B program represents the aligned progress of a local clean air leader and China’s aerospace industry — a vivid example of coordinated advancement across China’s advanced manufacturing ecosystem.

Moving forward, Mayair will continue to deepen core clean air technology, deliver more reliable product performance and scenario-specific customized solutions, and support more national key projects and high-end manufacturing scenarios, advancing alongside Chinese manufacturing to explore further into deep space.
