🌬️ Balboa Genesis Air Blower – G120‑2AN‑S (1200 W, Non-Heated, Pneumatic On/Off)

Powerful pneumatic bubble blower delivering 2600 L/min airflow for large hot tubs and swim spas – no control panel needed 💨

📋 Product Overview

The Balboa Genesis G120‑2AN‑S is a high-performance 1200 W air blower engineered for large hot tubs, swim spas, and commercial whirlpool baths. Part of the renowned HydroAir Genesis range manufactured by Balboa Water Group in Denmark, this pneumatic model delivers exceptional bubble massage performance without requiring an electronic control system.

Operating via a simple air push-button, the G120‑2AN‑S provides effortless on/off control while generating powerful airflow of approximately 2600 litres per minute. This makes it ideal for systems running 8–15 air jets, creating an invigorating hydromassage experience. The blower draws ambient air from its surroundings, meaning strategic placement near warm components like heaters or pumps can provide naturally warmer bubble delivery for enhanced comfort.

Designed for reliability and longevity, the Genesis series features automatic dry-out functionality to protect internal components from moisture damage, thermal overload protection, and IPX5-rated splash-resistant construction. Whether you’re upgrading an existing pneumatic system or installing a new large-capacity spa, this blower delivers professional-grade performance backed by European manufacturing standards.

🛠️ Installation Considerations

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

Electrical Requirements

• Supply Voltage: 230–240 V AC, 50 Hz
• Current Draw: Approximately 5.2 A
• Cable: 1 m bare-end supply cable provided
• Wiring Colours (Class I): Earth = Yellow/Green, Neutral = Blue, Live = Brown
• Isolation: Fixed wiring switch with minimum 3 mm contact separation in each pole required

Mounting & Positioning

• Suitable for mounting below whirlpools and spas
• Secure using three screws through the rubber mounting feet
• Position in a well-ventilated location protected from flooding
• Avoid cold air intake – position near warm components where possible for warmer bubble delivery
• Must not be accessible to spa users without tools
• Ensure access is maintained for future inspection and maintenance

Pneumatic Connection

• Connect 3 mm internal diameter flexible tubing from blower to air button
• Air button located at rear of blower housing

Plumbing Requirements

• Rotatable 1½″ BSP × 32 mm union included for flexible alignment
• Critical: Install either a double air loop with one check valve, OR two check valves, above maximum water level to prevent water backflow into the blower

Thermal Protection

• If thermal protection activates, power must be disconnected and reconnected only AFTER the blower has cooled to room temperature

Dry-Out Function

The automatic dry-out activates 30 minutes after the blower stops, running for 5 minutes to purge moisture from the air system. This feature is integral to pneumatic models and helps protect internal components.
