9393020003 ebmpapst vacuum pump fan

Description

The ebmpapst 9393020003 is a high-precision 24 VDC medical-grade centrifugal fan, specifically engineered for highly dynamic pressure requirements in respiratory and vacuum applications. This unit utilizes a 5-blade specialized turbo impeller driven by a high-speed brushless DC motor, reaching an exceptional 18130 RPM to ensure rapid pressure modulation. Its structural integrity is anchored by a medical-grade fiberglass-reinforced plastic housing and a high-performance ball bearing system designed for extreme rotational speeds. The 3-wire configuration provides a Speed Sensor (FG) for closed-loop monitoring, making it a critical component for CPAP machines, ventilators, and medical vacuum pumps where precise air delivery and ultra-fast acceleration are mandatory.
