Products Description

Airport terminals are huge, tall, and always crowded - and they cannot afford fan noise or drafts that disturb passengers waiting at gates. This geared-motor HVLS fan is designed for large public tall spaces. A Nord (Germany) integrated gear-motor runs quietly and maintenance-free at roughly 50 rpm (max 55–100 RPM by model), with a Danfoss (Denmark) or ABB (Switzerland) variable-frequency drive rated for long-hour, high-temperature, dusty duty. Aviation aluminum-magnesium alloy airfoil blades and a streamlined tail wing keep drag and noise low while pushing a wide vertical air column down to passenger level, where it spreads into a 1–3 m horizontal layer at a gentle, adjustable 1–5 m/s. A single unit covers 2,000+ m², so a large concourse needs only a few fans. Dual-row deep groove ball bearings at the shaft sleeve protect the gear oil seal, and VFD auto alarm and stop on abnormality protects safety in a public space.

Public infrastructure buyers need equipment that is engineered to the building rather than plopped into it. We manufacture to customer technical drawings and prototypes, adapting blade diameter, mounting configuration, and voltage to the terminal's roof structure and power supply. Drawing-based manufacturing ensures the fan integrates with the building's architecture and operations from day one.
