High-Duty Boxed Axial Fans
Product overview
Packaged axial fan modules integrated into rigid protective or acoustic enclosures for high-duty supply and extract applications.
RAFAVENT AXIAL FAN SUBFAMILY

RAFAVENT RF-HDB SERIES
Direct-drive axial fan modules packaged inside rigid steel enclosures for protected, serviceable or acoustically treated supply and extract duty.
Galvanized or painted double-skin steel enclosure with removable service panels; acoustic infill, weather protection and base frame are project options.
Internal direct-drive tubular axial fan module with aluminium impeller; production balancing and vibration acceptance required before dispatch.
Flexible internal connections, anti-vibration mounts, guards, access doors and external terminal box are configured 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 and represents the internal fan-module baseline before enclosure attenuation, duct reflection, guards and system effects. Final box envelope, mass, insertion loss and external duty require project-specific calculation.
Open a model to view its six-point preliminary Q–Ps curve. Curves represent the internal fan module; enclosure components and connections add resistance that must be included in final unit selection.
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.
