Advanced Cooling Solution
The backward-curved impeller of the R1G220-AB71-02 does not require a scroll housing to function effectively. This allows for installation in plenum chambers or custom ducting. The EC motor runs cooler than AC equivalents, extending the lifespan of the bearing system. The integrated electronics provide a tacho signal for continuous monitoring of fan health.
