Our Innovations

Industry Focused Products!

Smoke Exhaust Damper

The smoke exhaust damper responds rapidly to smoke or heat signals, enabling quick discharge of smoke and hot gases during fire events. Compared with standard designs, it delivers lower air leakage, superior sealing, and dual-mode (remote/manual) control. Fabricated with galvanized steel, it ensures stability in high-pressure and high-temperature conditions.

Integrated Air Grille Unit

The integrated air grille unit combines air supply with lighting, sprinklers, and detection modules in a unified panel, delivering superior space utilization and architectural aesthetics. Compared with traditional separate installations, it ensures faster on-site assembly, centralized maintenance, and a refined visual effect. Constructed with high-strength 6063 aluminum alloy and electrostatic powder coating, it offers excellent corrosion resistance and long-term durability.

Fire Damper

The fire damper is engineered to automatically close under high temperatures or fire alarm signals, effectively preventing flame and smoke spread. Compared to conventional dampers, YaoAn adopts advanced riveting and H62 brass bearings for enhanced strength, sealing, and service life. Built with high-temperature galvanized steel, it guarantees fire resistance and safety compliance.

Volume Control Damper

The volume control damper enables precise manual or motorized regulation of airflow, ensuring optimal balance in ventilation systems. Compared with conventional dampers, it offers smoother operation, lower pressure loss, and better compatibility with automation systems. Made from corrosion-resistant galvanized steel, it provides reliable durability.

Louver Air Diffuser

The louver air diffuser features adjustable blades for precise airflow control and uniform air distribution. Unlike single-blade grilles, its synchronized mechanism enables smooth regulation with improved comfort and efficiency. Made from extruded aluminum alloy with high surface finish, it ensures lightweight strength and seamless integration with architectural interiors.

Silencer

The silencer applies advanced acoustic chambers and fiberglass absorption materials to effectively reduce airflow noise with minimal pressure drop. Compared with regular silencers, it offers superior noise attenuation, validated by acoustic simulation analysis. Its galvanized steel shell and micro-perforated inner lining ensure structural integrity and sound performance.

Air Damper

The motorized air damper offers highly accurate airflow modulation via smart actuators, supporting integration with building automation systems. Unlike manual dampers, it ensures real-time adjustment, improved energy efficiency, and safer system control. Constructed with heavy-duty galvanized steel, it provides long-lasting performance.

Sound Attenuation Plenum Box

The sound attenuation plenum box combines static pressure stabilization with acoustic noise reduction. Compared to standard plenum boxes, it offers better airflow uniformity and stronger sound absorption due to internal fiberglass lining. Manufactured with galvanized steel and sealed joints, it ensures acoustic comfort and system efficiency.

Motorized Fan

The motorized fan utilizes aerodynamically optimized impellers and precision balancing to deliver high airflow efficiency, low vibration, and low noise. Compared with conventional fans, it achieves 20–30% performance improvement and enhanced operational stability. Its frame is made of galvanized steel with industrial-grade bearings for long service life.
