inver-CORE Silence
New Generation Technology
Twin-Rotary
The twin rotors work together to balance the movement to minimize vibration for higher efficiency & quieter operation.
Centrifugal Fan
It only runs at half the speed of a conventional blade fan. Not only greatly reduce the mechanical noise but also provides sufficient airflow.
"Air Blower" Duct Design
This design greatly reduces the wind noise of pool inverter heat pump and speed up the efficiency of the air energy exchange.
Intelligent Control System
Cubic Intelligent Control System insures all parts work together smoothly and efficiently.
inver-CORE Silence Features
Multi-backward-curved blades with large-diameter impeller
design. At the same airflow rate, the larger impeller achieves air
delivery at lower rotational speeds. Reduced speed means less air
disturbance and significantly decreased blade-tip vortex noise.
Backward-curved blades reduce airflow impact and trailing vortex
intensity, effectively lowering broadband noise. The multi-blade
structure increases blade-passing frequency while reducing load
per blade, resulting in smoother airflow.
- Ultra-quiet performance: 46–52 dB(A) at full load (1m)
- Low rotational speed for quiet airflow
- Low rotational speed for increased lifespan
- Less noise from reduced air turbulence
Same Decibel,
Quieter Feel.
The unique “Air Blower” duct of the CUBIC centrifugal fan effectively converts dynamic airflow into static pressure, significantly reducing wind turbulence and high-frequency hiss. Its carefully engineered geometry provides smooth airflow transitions, minimizing blade-to-tongue interaction noise. The result is a stable and gentle airflow, enhancing overall acoustic comfort and energy efficiency.
- Smooth airflow reduces noise
- Eliminates harsh, high-pitched sounds
- Provides stable and gentle air delivery
