With years of deep expertise in the design and manufacturing of elevator cross-flow fans, we possess comprehensive capabilities spanning the entire process—from aerodynamic optimization, impeller design, and motor matching to dynamic balancing, noise control, and full-unit performance testing. Our products support the complete lifecycle of elevator ventilation systems, ensuring fresh air within the cabin alongside quiet, reliable operation.
We translate elevator ventilation requirements into quiet, efficient, and reliable airflow solutions — across analysis, design, manufacturing, testing, and delivery.
Complete cross‑flow fan systems for new elevator installations, from car ventilation requirement analysis and mounting‑space survey, through prototype validation to batch delivery, with full process engineering control.
Replace aging or failed cross‑flow fans in existing elevators with optimized airflow and noise performance — executed with minimal elevator downtime to ensure normal building operations.
High‑efficiency external‑rotor motors matched with custom‑profiled V‑shaped impellers, optimized through aerodynamic design and dynamic balancing, delivering low‑noise, high‑static‑pressure, and long‑lasting airflow performance.
Precision‑formed volute flow paths with integrated sound‑absorbing materials, combined with optimally positioned inlet/outlet openings, ensuring uniform cabin airflow, quiet operation, and passenger comfort.
Supports both manual and automatic speed selection modes, with optional temperature sensors and over‑current/over‑voltage protection circuits, compatible with a wide range of elevator control system interfaces.
Full inspection of noise, vibration, airflow, and insulation performance, accompanied by installation guidance and routine maintenance recommendations, ensuring stable fan operation throughout the entire elevator lifecycle.
Every cross‑flow fan we design is engineered as an integrated whole — impeller, motor, volute, inlet, and noise‑reduction structures work in perfect harmony.
Multi‑blade V‑shaped impeller, optimized through aerodynamic profiling and dual‑plane dynamic balancing, delivering high‑efficiency, low‑turbulence airflow delivery.
Integrated external‑rotor asynchronous or brushless DC motor, directly driving the impeller without belt transmission losses — compact, maintenance‑free, and highly reliable.
Precision‑formed spiral volute casing, with flow‑path curvature optimized via CFD simulation, effectively converting dynamic pressure into static pressure for superior air‑delivery efficiency.
Bell‑mouth inlet with an integrated guide ring, channeling airflow uniformly into the impeller to minimize vortex losses and intake noise.
Multi‑angle fixed guide vanes that straighten and direct the discharge airflow, preventing turbulent overlap and ensuring even air distribution throughout the elevator cabin.
Micro‑perforated sound‑absorbing material combined with a damping layer applied to the inner volute surface, suppressing broadband aerodynamic noise at both source and propagation paths.
High‑precision ball bearings paired with a hardened and tempered chrome‑plated main shaft, verified through strict concentricity testing, ensuring long‑term stable operation with minimal vibration.
Integrated wiring compartment supporting both manual and automatic speed selection modes, with optional temperature and over‑current protection modules, compatible with a wide range of elevator control systems.
Define airflow, static pressure, noise, voltage, and mounting interface specifications; review project timeline and quality requirements.
Determine impeller type and dimensions, motor selection, volute flow path, and inlet/outlet layout; output 3D models and design documentation.
Complete volute stamping/forming, impeller injection molding or sheet‑metal fabrication, main shaft machining, and end‑cover accessories production.
Complete stator winding, magnet bonding, bearing press‑fitting, and rotor balancing; verify electrical parameters and insulation performance.
Stack multi‑stage impellers onto the main shaft and secure; perform dual‑plane dynamic balancing to eliminate rotational vibration.
Every motor, impeller and electrical system is validated against international safety and performance codes — because in elevator ventilation, reliability is never optional.
