Three Bubble Intensities Plus Massage Mode – All From a Single Air Button

📝 Product Overview

The Balboa/HydroAir Genesis G50‑2ANT‑S is a versatile 500W air blower featuring built-in 3-speed pneumatic control with pulsating massage mode, designed specifically for whirlpool baths and small hot tubs.

🏠 Real World Examples & Applications

🛁 Whirlpool Bath Upgrade

Ideal for residential whirlpool baths where adjustable bubble intensity enhances the bathing experience. Start with vigorous high-speed bubbles for invigorating massage, then gradually reduce to gentle low-speed relaxation – all controlled by a single air button mounted conveniently at bath-side. The massage mode adds therapeutic pulsation without any electronic complexity.

💆 Small Hot Tub Installations

Perfect for compact hot tubs requiring versatile air blower control without electronic spa packs. The 3-speed function allows users to customise their hydrotherapy experience based on preference and mood. Being non-heated, it’s particularly suited to well-insulated spas or warmer climates where air heating isn’t essential.

🔄 Pneumatic System Retrofit

An excellent upgrade for existing single-speed pneumatic blower installations. The G50‑2ANT‑S uses the same physical dimensions and connection style as other Genesis 500W models, making it a straightforward replacement that adds multi-speed functionality to your current setup without rewiring or new control systems.

🏢 Commercial Whirlpool Baths

Suitable for hotel bathrooms, B&B guest suites, and holiday let properties where simple, reliable operation is essential. The pneumatic control means guests can easily adjust bubble intensity without training, while the automatic 30-minute shut-off provides safety and energy efficiency.

♨️ DIY Spa Projects

Well-suited for home builders creating bespoke hydrotherapy installations. The pneumatic control eliminates complex electronics, while the 3-speed programme offers impressive functionality from minimal components. Combined with a standard air button and check valves, you have a complete, adjustable bubble system.

🛠️ 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
• Position near pumps or heaters if ambient warmth is desired (non-heated model)

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
• Protect from direct water contact at all times

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
• Automatic dry-out function activates 30 minutes after the blower is switched off, running for 5 minutes to purge moisture from the air system
• Never use as a portable unit or with separate portable mats
• Water flowing back from the bath must never contact the blower
