RL90-18/06 ebmpapst 115V 121mm AC Centrifugal Fan

Description

The ebmpapst RL90-18/06 (Model: VHS0090XQHCS / PN: 9214014024) is a professional-grade 115 VAC centrifugal fan featuring a forward-curved impeller, designed for high-pressure cooling in industrial control systems and infrastructure. Operating on a 115 VAC supply at 50/60 Hz, this unit delivers a dual-rated performance of 21/21 W with an effective output power of 1.37/2.37 W. Within its 121 x 121 x 37 mm glass-fiber reinforced PBT scroll housing and sheet steel base, it maintains a nominal speed of 2450/2550 RPM, generating 42 m³/h (24.7 CFM) of radial airflow. Engineered for durability, the RL90-18/06 features ball bearings and an IP20 protection rating, providing a robust thermal solution for environments from -30 °C to 85 °C.
