CTF (380V) Three Phase Vertical Throw Roof Type Radial Fan
The CTF (380V) Vertical Throw series is the ideal three-phase roof-mounted radial fan for ventilation systems requiring both external motor protection and vertically directed air discharge. By combining an externally mounted motor with a dedicated air router that directs discharge airflow straight upward, this series provides reliable continuous operation at up to 120°C while keeping discharged exhaust air well clear of the rooftop and all adjacent building surfaces — the definitive choice for demanding commercial kitchens, industrial facilities, and hot air intake applications.

- Count on rapid, reliable global delivery.
- Backed by 24 years of expertise.
Areas of Use
The CTF (380V) Vertical Throw series is specifically designed for applications where both motor protection from the exhaust airstream and vertical air discharge are critical requirements. Its unique upward-throw design makes it the preferred choice wherever horizontal discharge could cause re-entrainment or contamination issues. Use these specialized roof radial fans confidently in:
- Commercial kitchen exhaust systems requiring vertical air discharge
- Industrial ventilation with hot or aggressive exhaust air up to 120°C
- Applications where horizontal discharge would cause re-entrainment of exhaust air
- Manufacturing facilities and workshops with oily or chemically laden exhaust
- Buildings and rooftops where upward exhaust discharge is architecturally or technically required
Key Features & Specifications
Vertical Air Discharge via Integrated Router: Features a dedicated air router that directs all discharged exhaust air vertically upward, ensuring maximum dispersion well above the rooftop and eliminating any risk of exhaust air re-entering nearby fresh air intakes or contaminating adjacent building surfaces.
External Motor Design — Up to 120°C Continuous Operation: The motor is positioned entirely outside the airflow path, providing full protection from hot, oily, humid, or chemically aggressive exhaust air. This enables reliable continuous operation at airstream temperatures up to 120°C — far exceeding the capability of standard internally-motored roof fans.
Heavy-Duty Galvanized Steel Construction: The robust body is manufactured from high-quality, corrosion-resistant galvanized steel, ensuring excellent structural integrity and reliable long-term performance across all rooftop environments and weather conditions.
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 — maintaining consistent performance even as system conditions vary over time.
Three-Phase 380V Motor: Driven by a robust three-phase 380V motor, providing the high power density, reliability, and continuous duty performance required for demanding commercial and industrial rooftop ventilation applications.
Ideal for Oily Kitchen & Industrial Exhaust: The combination of external motor protection and vertical discharge makes this series the definitive solution for commercial kitchen exhaust and aggressive industrial ventilation — protecting both the motor and the building from the effects of oil-laden, high-temperature exhaust air.
