Product Description
Suction Blade FI 254 mm, Angle 28° – ebm-papst 73814-2-3634
ebm-papst 73814-2-3634 is a metal suction blade (air flow direction: suction) designed for iQC series EC motors. 254 mm diameter and 28° blade angle provide high flow efficiency at low noise levels – ideal for evaporators in refrigerated display cases, refrigerated cabinets, and low-temperature chambers.
Features › Benefits › Advantages: Aluminum construction is corrosion-resistant and lightweight, extending blade life and reducing motor load. 28° angle provides optimal balance between air flow and noise level, lowering operating costs and improving equipment comfort.

Applications and Key Benefits
- Efficient Cooling: 28° blade angle optimizes the ratio of air flow to power consumption – the blade delivers maximum air through the evaporator at low noise levels.
- Durable Aluminum Construction: Aluminum sheet is resistant to moisture, condensate, and cleaning agents used in food refrigeration, eliminating corrosion risk.
- Direct Mounting (drop-in): The blade is a direct replacement (1:1) for older Q series and shade-pole motors – no additional adapters required beyond standard M4 flange.
- Wide Compatibility: Fits iQC 3608, iQC 3612, and iQC 3612+ motors, and once mounted, supports all EC motor operating modes (ROS, ROD, two-speed operation).
- Suction Direction (V): Draws air through the evaporator from the cooled space side, ensuring even temperature distribution in the unit and reducing blade icing.
