VKF Inline Axial Duct Fan
VKF low pressure axial fans are designed for duct installation with connecting flanges, providing high airflow for supply and exhaust ventilation systems.
VKF inline axial duct fan model range
Simplified VKF selection groups based on the catalog series. Final model selection should confirm airflow, pressure, duct size, voltage, frequency, noise, and site conditions.
| Model Group | Mounting | Voltage | Frequency | Max Airflow | Power Range |
|---|---|---|---|---|---|
| VKF 200-300 | Inline duct flanges | 1 phase 230V / 3 phase 400V | 50/60Hz | 875-2,390 m3/h | 55-178 W |
| VKF 350-450 | Inline duct flanges | 1 phase 230V / 3 phase 400V | 50/60Hz | 2,590-5,350 m3/h | 140-325 W |
| VKF 500-630 | Inline duct flanges | 1 phase 230V / 3 phase 400V | 50/60Hz | 5,380-12,400 m3/h | 220-979 W |
| VKF 710-800 | Inline duct flanges | 3 phase 400V | 50Hz listed | 12,000-25,000 m3/h | 700-1,850 W |
Flanged inline axial fan for ducted supply and exhaust ventilation
The VKF inline axial duct fan is a low pressure axial fan in a steel casing, designed for installation into ventilation ducts by means of connecting flanges. It is used where high airflow is required at relatively low system resistance.
VKF fans are suitable for combined supply and exhaust ventilation systems in industrial, commercial, warehouse, and MEP duct applications. The fan is fitted with an external terminal box mounted on the casing for electrical connection.
For Saudi Arabia projects, selection should be reviewed by airflow, duct size, static pressure, voltage, frequency, controller requirement, and installation environment.
Key features for VKF inline axial duct fans
The VKF series is built for ducted ventilation systems where direct inline axial airflow, flanged connection, and project-ready selection are required.
