RAFAVENT RF-AX-SE SERIES
Direct-drive cylindrical axial fans for ducted general ventilation and low-to-medium pressure industrial supply or extract systems.
Rolled or welded steel cylindrical casing with inlet and outlet flanges; short and long casing options.
Direct-drive aluminium axial impeller; production balancing and vibration acceptance required before dispatch.
External terminal box and internal motor support; mounting feet, flexible connectors, guards, anti-vibration mounts and silencers available by project.
Normal clean-air duty basis −20 to +50 °C. No smoke, ATEX, marine or high-temperature certification is claimed for this preliminary series.
Recommended Q and Ps describe the intended selection envelope and are not opposite corners of a guaranteed operating point. Estimated free-field A-weighted sound pressure at 3 m has ±6 dB(A) uncertainty before duct, reflection, guard, silencer and system effects.
Open a model to view its six-point preliminary Q–Ps curve.
Confirm airflow, total static pressure, duct diameter, installation orientation, straight inlet/outlet conditions, voltage and phase, control method, temperature, corrosion class, permissible sound level and accessories before order.
Final dimensions, connection details, materials, motor data and project drawings are issued for the selected configuration after engineering review.
Provide level support, flexible connections, guarded drive components, alignment checks and safe maintenance access. Follow the approved project-specific O&M document.
Selection tables and calculated curves on this page are preliminary engineering guidance, not certified RAFAVENT test ratings. Confirm the operating point and controlled documents before order.
