Product applications
An air curtain is a powerful fan that creates an invisible high-speed air barrier at entrances. It isolates interior and exterior air environments, maintaining temperature separation. By preventing conditioned air from escaping and blocking dust, smoke, and flying insects, it significantly saves energy.
Adjustable Guide Louver
Our new guide louver design can be adjusted to direct air flow in various directions, enhancing flexibility.
High-Quality Ball Bearings
We use high-quality ball bearings instead of oil bearings, ensuring longer lifespan, smoother operation, and quieter performance.
100% Copper Wire Motor
Our motor uses pure copper wire with low temperature rise, ensuring consistent and reliable operation without failure.
Low-Noise Multi-Blade Impeller
The unequal pitch and multi-blade impeller design reduces noise and vibrations, providing a quieter environment.
