RAFAVENT RF-ID-MF SERIES
Compact direct-driven mixed-flow units for circular duct supply and extract duties.
Galvanized or coated steel cylindrical casing, mixed-flow impeller, downstream guide vanes and direct drive.
Removable service section and external terminal box; provide safe access without loading the adjacent duct.
Flexible connectors and independent supports are recommended. Any-orientation installation requires verified support, drainage and terminal-box access.
Single-phase basis through Ø315; three-phase basis from Ø350. EC execution is an engineered option, not a general claim.
Preliminary clean-air duty −20 to +50 °C. Not for grease, abrasive dust, smoke control, ATEX or certified high-temperature duty unless separately documented.
Standard impeller series Ø200, Ø250, Ø280, Ø315, Ø350, Ø400, Ø450 and Ø500.
Selected motor includes a preliminary 15% margin. Estimated sound at 3 m has ±6 dB(A) uncertainty before duct, attenuation, room and installation effects.
Open a model to view its six-point preliminary Q–Ps curve.
Confirm airflow, static pressure, air density, temperature, duct diameter, upstream and downstream straight length, mounting orientation, service access, voltage/phase, speed-control method, operating range, permissible sound level and conveyed-air composition before order.
Final dimensions, connection details, materials, motor data and project drawings are issued for the selected configuration after engineering review.
