Experience warm, soothing bubble massage with whisper-quiet performance – the perfect upgrade for whirlpool baths and compact hot tubs 💨

📋 Product Overview

The HydroAir Genesis G50-2HN-S is a premium 500W heated air blower engineered for whirlpool baths, spas, and small hot tubs.

🛠️ Installation Considerations

⚠️ Professional Installation Recommended – All electrical work must be carried out by a qualified electrician in accordance with national wiring regulations.
