YFW-3000

Hard-bearing balancing machine for dynamic balancing of fan impellers and blowers

The YFW-3000 is a hard-bearing balancing machine designed for medium and small fan manufacturers. With the capacity to balance impellers up to Ø3000 mm in diameter, it is ideal for testing and correcting unbalance in large fan rotors. Its integrated machine base allows balancing of multiple impeller sizes with ease, while offering the full functions of a general-purpose balancing machine. The system is easy to install and calibrate, delivers accurate and rapid measurements, and provides clear data display.

Features

Part of the YFW hard-bearing series, built with a horizontal universal joint structure, designed as an upgraded version of the YYW balancing machine series.
While maintaining the same rotor mass range as comparable YYW hard-bearing balancing machine models, it expands both the maximum rotor diameter and the drive power capacity, improving accuracy and versatility.
Retains all the functionality of general-purpose balancing machines while being optimized for fan impeller testing.
Well-suited for fan manufacturing plants, where reliable and precise impeller balancing is critical.
