Wento RFC4-035 XLB (SS) 350 mm Stainless Suction Axial Fan – 1,370 RPM, 138W, 2,980 m³/h

Wento RFC4-035 XLB (SS) is a 350 mm suction axial fan with stainless steel blades. It is designed for cold room evaporators, condensing units and ventilation applications in humid/corrosive environments; in saline, acidic and condensing environments where standard galvanized blades corrode, the stainless (SS) blade construction provides a long service life.

Stainless Blades: The Fan for Humid and Corrosive Environments

• 2,980 m³/h airflow — strong suction in the 350 mm class; balanced noise/performance at 1,370 rpm.
• Suction (draw-through) direction: Draws air toward the motor side; the correct direction for draw-through mounting on evaporator and condenser coils.
• IP54 protection: Motor protected against dust and water splashing from any direction — safe in cold room condensation.
• Wire guard protected: Ready to mount; the guard feet are screwed directly to the housing.
• Documented efficiency: Static efficiency grade 61.4% (ErP measurement category A).

Technical Specifications and Installation Notes

• Model: Wento RFC4-035 XLB (SS)  |  stainless blades
• Blade Diameter: 350 mm  |  Air Direction: Suction (draw-through)
• Speed: 1,370 rpm (4-pole)

• Efficiency: Static 61.4% (measurement category A)

• 🔧 Verify the air direction before replacement. If you fit a suction fan in place of a blowing fan, coil efficiency drops; check the direction arrow on the old fan's label.
• Blade diameter + speed + direction must all match; if you are looking for a 1,370 rpm suction equivalent for a 350 mm opening, this fan is a direct replacement.
• Check the capacitor connection: The run capacitor of single-phase motors is in the terminal box; keep the same capacitor value when replacing.
• Do not scratch the stainless blades: Do not put load on the blade edges during installation; if the balance is disturbed, vibration shortens bearing life.
