RL90-18/50 ebmpapst 230V 121x121x37mm AC Centrifugal Blower

Description

The ebmpapst RL90-18/50 is an industrial-grade 230 VAC AC Centrifugal Blower designed for localized spot cooling and high static pressure ventilation. Constructed with a fiberglass-reinforced plastic (PBT) scroll housing, fiberglass-reinforced plastic (PA) impeller, and precision ball bearings, it has a total weight of 560 g and dimensions of 121 x 121 x 37 mm. Driven by a shaded-pole AC motor operating at 50 Hz, it draws a rated current of 0.14 A with an input power consumption of 19.0 W across an operating voltage range of 207 – 253 VAC. Operating at a nominal speed of 2450 RPM, it produces a max. air flow of 23.54 CFM (40.00 m³/h / 0.67 m³/min) and a max. static pressure of 19.37 mmH₂O (190.00 Pa / 0.76 inAq) with a sound pressure level of 51.0 dBA (5.6 Bel sound power level). Engineered for an operating temperature range of -20 to +70 °C and a life expectancy of 20,000 hours at 40 °C, it features IP20 degree of protection, Class I protection rating, Class B motor insulation, impedance overload protection, 310 mm TR 64 AWG 22 lead wire connection, and compliance with CE, CSA, UL, and VDE standards.
