    Why RF-250 Excels in Smoke Ventilation?

    1. Instant Emergency Activation

      • Achieves full speed in seconds, ensuring rapid window opening for smoke extraction.

      • High stall torque (306 g-cm) overcomes initial resistance in window mechanisms.

    2. Robust Design for Critical Environments

      • Wide voltage tolerance (6V–28V) guarantees operation during voltage fluctuations.

      • Class F insulation withstands high temperatures in fire scenarios.

    3. Smart System Integration

      • Compatible with fire alarm interfaces for automated triggering.

      • Low standby current (0.47A at peak efficiency) reduces energy waste.

    4. Compact & Lightweight

      • Minimal space requirements (22mm diameter) for retrofit installations.

      • Aluminum housing enhances heat dissipation in continuous duty cycles.

    Typical Applications

    • Industrial: Factory skylights, warehouse vents

    • Commercial: Shopping mall atriums, office building smoke shafts

    • Public Spaces: Hospitals, stadiums, subway stations

    • High-Rise Buildings: Complies with international smoke control standards
