HTF Series Fire-fighting Smoke Exhaust Axial Fan
The HTF series is suitable for fire smoke extraction and daily ventilation in venues such as hotels, restaurants, shopping malls, cinemas, stadiums, schools, auditoriums, high-end residential buildings, and industrial & mining enterprises. It also offers an optional dual-speed motor: operating at low speed during normal times for routine ventilation, while automatically switching to high speed during a fire—triggered by the electrical control system—to swiftly exhaust smoke within 30 minutes, ensuring safe evacuation of occupants.
The fan is designed for conveying air or other non-flammable, non-corrosive gases; the gas must be free of sticky substances, and the concentration of dust and hard particulate matter should not exceed 150 mg/m³.
• When ventilating, the intake air temperature must be ≤ 80 ℃;
• During fire smoke extraction, it can operate continuously at 280°C for ≥ 30 minutes.
