🌀 Balboa Genesis Air Blower – G50‑2AN‑S (500W, Non‑Heated, Pneumatic On/Off)

Simple, Reliable Bubble Power – One Press, Pure Relaxation

ℹ️ Product Overview

The Balboa/HydroAir Genesis G50‑2AN‑S is a straightforward, dependable 500W air blower with pneumatic on/off control, engineered for whirlpool baths and small hot tubs where simplicity and reliability matter most. One press of a standard air button activates powerful bubble massage; another press turns it off – no electronics, no complexity, just proven performance.

Encased in HydroAir’s signature compact blue polypropylene housing, the G50‑2AN‑S delivers approximately 1,800 litres per minute of airflow at 1.8m head pressure, providing vigorous bubble action for 8–15 air jets. The rotatable outlet and included union fitting make installation straightforward, while the pneumatic control eliminates the need for electronic spa packs or control boards.

As a non-heated model, this blower is the economical choice for installations where warm-air injection isn’t required, or where the unit benefits from ambient warmth in the equipment bay near pumps or heaters. Manufactured by HydroAir (a division of Balboa Water Group) to European safety standards EN60335-1 and EN60335-2-60, the G50‑2AN‑S delivers the trusted Genesis quality that spa professionals rely on across the UK and Europe.

🎯 Real World Examples & Applications

🛁 Whirlpool Bath Installations

The ideal choice for residential whirlpool baths requiring reliable, no-fuss bubble operation. The pneumatic control integrates seamlessly with bath-side air buttons, providing instant bubble massage at the touch of a finger. Perfect for straightforward installations where adjustable speed isn’t needed.

An excellent like-for-like replacement for ageing or failed pneumatic Genesis blowers. The G50‑2AN‑S maintains the same physical dimensions, connection style, and control method as previous models, making swap-outs quick and straightforward without plumbing or wiring modifications.

🏠 Budget-Conscious Spa Upgrades

The non-heated, single-speed design offers an economical entry point into the Genesis range. For installations where warm air injection isn’t essential – particularly in well-insulated spas or warmer climates – this model delivers excellent bubble performance at a lower price point.

🏢 Holiday Let & Rental Properties

Well-suited for self-catering accommodation where guests need simple, intuitive controls. One button, one function – guests can enjoy bubble massage without instruction manuals or complex control panels. The robust Genesis construction handles frequent use reliably.

⚡ Simplified DIY Projects

Perfect for home builders creating custom hydrotherapy installations. The pneumatic control eliminates electronic complexity, requiring only an air button, flexible tubing, and basic plumbing. Combined with appropriate check valves, you have a complete, reliable bubble system.

💡 Ambient Heat Benefit

Although non-heated, the G50‑2AN‑S can benefit from ambient warmth when positioned near pumps or heater units in the equipment bay. This natural warming effect can reduce the temperature differential of injected air without the additional power consumption of a dedicated heating element.

🛠️ 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: 230-240V AC, 50Hz
• Current Draw: Approximately 2.2A (500W)
• Cable: 1m bare-end supply cord (Class I or Class II wiring options)
• Isolation: Installation must include a fixed wiring switch with minimum 3mm contact separation in each pole
• Wire Colours: Brown (Live), Blue (Neutral), Yellow/Green (Earth – Class I only)

Mounting Position

• Suitable for mounting beneath whirlpool baths and hot tubs
• Secure using three screws through the rubber feet
• Must not be accessible to bathers without use of a tool
• Ensure adequate ventilation to prevent overheating
• Consider positioning near pumps or heaters if ambient warmth is desired

Plumbing Connections

• Outlet: Rotatable 1½” BSP × 32mm union (included)
• Pneumatic Control: 3mm internal diameter flexible tubing to air-button
• Critical: Install double air loop AND check valve (or two check valves) above maximum water level to prevent water backflow into the blower

Ventilation & Clearance

• Position in a well-ventilated location
• Avoid areas prone to flooding or direct water spray
• Ensure blower remains accessible for future inspection and maintenance
• Avoid cold air intake locations as this affects air temperature entering the water

Important Safety Notes

• Thermal protection will shut down the motor if overheating occurs; power must be disconnected and reconnected after cooling to room temperature before restarting
• Never use as a portable unit or with separate portable mats
• Water flowing back from the bath must never contact the blower
• If the power supply cord is damaged, it must only be replaced by the manufacturer, service agent, or similarly qualified person
