RAFAVENT RF-AW SERIES
Wall-Mounted Axial Fans — Technical Selection Data
Direct-drive axial fans for free-air or low-resistance wall, panel and framed-opening supply or extract applications.
RAFAVENT Engineering Calculation — Preliminary Selection — Non-Certified. Values are calculated at standard air density 1.20 kg/m³ and are not laboratory-certified ratings. Airflow, shut-off pressure and sound figures are not simultaneous guarantees. Final manufacture and selection require the project duty point and approved production drawing.
Construction and application
- Square galvanized or painted steel wall plate with protective guard.
- Direct-drive aluminium or engineered composite/steel axial impeller, dynamically balanced during production.
- Normal clean-air service; ambient duty basis −20 to +50 °C unless a project-specific motor and material review states otherwise.
- Wall or panel mounting; provide unobstructed inlet, make-up air and suitable weather protection where exposed.
Model selection table
Recommended Q and Ps columns describe the intended selection envelope; they are not the opposite corners of one guaranteed operating point. Estimated sound is free-field A-weighted sound pressure at 3 m, uncertainty ±6 dB(A), before wall reflection, guards, louvers or system effects.

Technical documents and dimensions
Final dimensions, connection details, materials, motor data and project drawings are issued for the selected configuration after engineering review.
Installation and maintenance
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.
