Description
The ebm-papst RLF35-8/14N (also known as RLF35814N) is a high-speed compact DC centrifugal blower engineered with an integrated scroll housing and a single-inlet forward-curved impeller measuring 51 x 51 x 15 mm (2.01 x 2.01 x 0.59 in). Operating on a nominal 24 VDC supply across a broad 14 to 28 VDC range, this radial blower delivers an aerodynamic performance of 5.7 CFM (9.6 m³/h) and achieves up to 6700 RPM while consuming just 4.3 W. The assembly features fiberglass-reinforced PBT plastic construction, precision dual ball bearings, electronic locked-rotor auto-restart, and reverse-polarity protection for maximum operational reliability under thermal stress.
Key Features
- High-Pressure Centrifugal Design: Forward-curved motorized impeller generates focused static pressure and radial discharge from compact 51x51x15mm housing.
- Precision Ball Bearing System: Engineered for maintenance-free continuous operation delivering an L10 service life rating of 60,000 hours at 40°C.
- Comprehensive Motor Protection: Integrated solid-state electronics safeguard the winding circuitry against reverse polarity connection and blocked rotor stall conditions.
- Robust Composite Housing: Glass-fiber reinforced plastic casing and impeller resist thermal distortion and mechanical stress in demanding enclosures.
- Wide DC Supply Window: Operates reliably between 14 VDC and 28 VDC, accommodating voltage fluctuations across industrial bus rails.

Applications
The ebm-papst RLF35-8/14N centrifugal blower is optimized for spot cooling across densely packed electronics where high static back pressure is required to force airflow through narrow ducting or restricted heatsinks. Common OEM installations include telecommunications transceivers, network router switches, small-format laboratory instrumentation, and embedded single-board industrial computing enclosures. It is also routinely deployed as a drop-in replacement blower for thermal management modules in precision medical devices and industrial drive logic controls.
