Quiet Performance & Precision Control

At the core of the K1-100 is the IceCap EVair 400 pinwheel pump, delivering efficient air and water mixing while maintaining quiet operation.

The pipeless output design allows for smooth, splash-free water exit below the sump waterline while offering precise control over water level and performance.

A multi stage bubble dispersing chamber increases contact time, improving foam stability and waste removal efficiency.
