Product Analysis: ebm-papst RL90-18/14 N
The ebm-papst RL90-18/14 N is a high-performance DC centrifugal fan (blower) from the RL90 series. Designed for 24V DC operation, this unit is significantly larger and more powerful than the RL48 series, featuring a 121mm scroll housing. It is the component of choice for applications requiring directed, high-pressure airflow, such as in air-conditioning systems, burner air intake, or large telecommunications racks.
Key Specifications
- Nominal Voltage: 24 V DC (Operating range 12..28 V).
- Dimensions: 121 mm x 121 mm x 37 mm.
- Airflow: Approx. 40 m³/h (depending on back pressure).
- Housing: Scroll housing of fiberglass-reinforced plastic (PBT).
- Impeller: Forward-curved plastic impeller.
- Bearing System: Ball bearings.
- Noise Level: 58 dB(A).
Application Notes
The RL90-18/14 N utilizes an external rotor motor with fully integrated commutation electronics. This ensures a compact design relative to its output. The blower design creates high static pressure, allowing it to force air through dense filters or heat sinks where standard axial fans would fail. It is protected against blocking and reverse polarity.
