GreenTech EC technology from ebm-papst delivers exceptional efficiency (up to 90% vs conventional asynchronous motors), drives better utilization of primary energy, and lowers thermal load – all extending your applications' service life. GreenTech products offer a variety of options, including monitoring (error codes, motor temperature, tach output, etc.), protection (against line undervoltage, phase loss, locked rotor, etc.), and speed-control options via PWM, DC voltage, or sensor input.

ACi4400 Series fans are a fully compatible alternative to classic 119 x 119 x 38 mm AC fans, with a technology upgrade to reduce energy costs. The series was designed to replace conventional AC fans that use low efficiency shaded-pole motors with GreenTech EC compact fans.

Compact W1G200 Series axial fans are based on the energy-saving motor (ESM) and offer high efficiency, energy savings, and more than 40,000 hours (4.5 years) of service life. The fans incorporate a plastic rotor, which is aerodynamically efficient and quiet.

The R3G190 Series features a RadiCal® impeller that has been optimized for low-loss flow of air through the blade channels. This innovative styling means no more drastic cross-sectional changes (a common source of losses in impellers), and results in increased aerodynamic efficiency and lower acoustic noise.
