RFB2008N RISUN 5V DC Micro Blower 20mm

Description

The RISUN RFB2008N is a Micro Blower (Centrifugal Blower) with dimensions of 20 x 20 x 8.5 mm. It operates on a nominal voltage of 5.0 VDC. The blower achieves a high speed of 14,000 RPM, consuming 0.625 W of power and drawing a maximum current of 0.145 A. It delivers an air flow of 1.51 m³/h (0.89 CFM) and a maximum static pressure of 73.6 Pa (0.294 inAq). This two-wire fan is protected by an IP58 rating and includes Lock Rotor and Auto Restart protection, making it ideal for extremely compact, high-pressure ventilation in portable electronics.
