Axial fans configured for direct installation on walls, panels or framed openings where the system requires free-air supply or extract.
Documentation workspaceRAFAVENT wall-mounted axial fan — representative direct-drive configuration.
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.

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.

Selection requirements
Confirm airflow, total system resistance, supply/extract direction, voltage and phase, operating temperature, corrosion exposure, control method, permissible sound level and required accessories before order.
Technical documents, dimensions and service
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.
Information required before selection
Required airflow and static pressure
Operating temperature and conveyed-air composition
Installation orientation, space and connection details
Electrical supply, control method and duty pattern
Sound, material and environmental constraints
Request an engineering selection
Send the duty point, installation arrangement, operating conditions and available drawings for a project-specific selection.
