Electronically Commutated. Artfully Controlled.

The Phoenix ECS takes our Phoenix EC 4″ fan and adds a built-in speed potentiometer. This allows for 100% controllability, enabling you to dial in the exact vacuum pressure needed for the specific slab. Whether you need to reduce noise or fine-tune suction for seasonal changes, the ECS provides the ultimate “set it and forget it” experience with precision speed control.

Engineered for efficiency, the Phoenix ECS features a Swiss-engineered motorized impeller designed for newer homes with porous sub-slabs (gravel). Built for footprints between 500–2,200 sq. ft., this 4″ fan delivers consistent, whisper-quiet radon mitigation. With its EC motor technology, it consumes a fraction of the power used by traditional fans while offering superior longevity.
