CTF (380V) - Three Phase Horizontal Throw Roof Type Radial Fan
The CTF (380V) Horizontal Throw series is the ideal three-phase roof-mounted radial fan for ventilation systems where the motor must be fully protected from the exhaust airstream. By positioning the motor completely outside the airflow path, this series provides continuous operation at up to 120°C — making it the preferred choice for kitchens, industrial applications, and any environment where hot, oily, or chemically aggressive exhaust air would damage a conventional motor. The discharged air is directed horizontally away from the building.

Areas of Use
The CTF (380V) Horizontal Throw series is specifically engineered for applications where conventional roof fans with internal motors would be at risk from the exhaust airstream — including hot, oily, humid, or fume-laden air. Its external motor design and horizontal air discharge make it the correct choice for demanding commercial and industrial rooftop ventilation. Use these high-protection roof radial fans confidently in:
- Commercial and industrial kitchen exhaust ventilation systems
- Industrial process ventilation with hot or chemically aggressive exhaust air
- Oily exhaust air environments in manufacturing facilities and workshops
- Any application requiring continuous operation with high-temperature airstreams up to 120°C
- Offices, retail spaces, and industrial buildings requiring robust rooftop exhaust
Key Features & Specifications
External Motor Design — Up to 120°C Continuous Operation: The motor is positioned entirely outside the airflow path, protecting it from the damaging effects of hot, oily, humid, or chemically aggressive exhaust air. This design enables reliable continuous operation at airstream temperatures up to 120°C — far beyond the capability of conventional internally-motored roof fans.
Horizontal Air Discharge: The discharged exhaust air is directed horizontally away from the building, preventing re-entrainment of exhaust air through nearby fresh air intakes and ensuring effective dispersion away from the rooftop and building facades.
Heavy-Duty Galvanized Steel Construction: The robust body is manufactured from high-quality, corrosion-resistant galvanized steel, ensuring excellent structural durability and long-lasting performance in all weather conditions and demanding rooftop environments.
Backward-Curved Radial Blades: Equipped with high-efficiency, backward-curved radial impellers that deliver powerful, stable airflow and high static pressure across a wide range of operating conditions — even in duct systems with significant resistance.
Three-Phase 380V Motor: Driven by a robust three-phase 380V motor, providing the high power density, reliability, and duty-cycle performance required for continuous industrial and commercial rooftop ventilation applications.
Suitable for Oily & Aggressive Kitchen Exhaust: Specifically recommended for commercial kitchen exhaust systems where oil-laden, high-temperature air would rapidly degrade a standard internal motor — ensuring long service life and minimal maintenance requirements in the most challenging kitchen environments.
