🌬️ HydroAir Balboa Genesis Air Blower – G90-2AN-S (900W, Non-Heated, Pneumatic On/Off)

High-capacity 900W pneumatic air blower delivering powerful bubble massage for medium to large hot tubs – simple push-button operation

📋 Product Overview

The HydroAir Balboa Genesis G90-2AN-S is a high-capacity 900W air blower engineered for medium to large whirlpool baths and hot tubs that demand serious airflow. Housed in HydroAir’s robust blue polypropylene casing, this pneumatic blower delivers powerful bubble action through simple push-button control – no electronic spa pack required.

With approximately 1.21 HP of motor power, the G90-2AN-S steps up where smaller blowers reach their limits. Supporting between 8 and 15 air jets, this model suits larger domestic installations and light commercial applications where consistent, powerful airflow is essential for an invigorating hydrotherapy experience.

The pneumatic control system activates via an air button, providing reliable on/off operation without electronic complexity. For installations requiring variable speed functionality, this blower is compatible with external speed controllers, offering an upgrade path without replacing the unit itself.

While classified as non-heated, strategic positioning near pumps or heaters allows the unit to draw ambient warmth from surrounding components. This practical approach delivers comfortable air temperatures during operation without the additional power consumption of an internal heating element.

Manufactured by HydroAir, a division of Balboa Water Group, the Genesis range is built according to European norms EN60335-1 with focus on EN60335-2-60, meeting the rigorous safety standards required for electrical equipment in wet environments. The Genesis name has become synonymous with reliability in the spa industry worldwide.

🎯 Real World Applications

♨️ Medium to Large Hot Tub Installations The G90-2AN-S excels in hot tubs with 8-15 air jets where standard 700W blowers struggle to deliver adequate airflow. The increased 900W power ensures consistent bubble pressure across all jets, eliminating weak spots and providing an even, invigorating massage experience throughout the tub.

🛁 Large Whirlpool Bath Systems Premium whirlpool baths with extensive jet configurations benefit from the G90-2AN-S’s enhanced capacity. The powerful motor maintains strong bubble action even with longer pipe runs or complex plumbing layouts that would reduce performance in smaller units.

💆 Hydrotherapy & Wellness Applications For therapeutic installations where consistent, powerful bubble massage is essential, this blower delivers reliable performance. The robust airflow supports effective hydrotherapy treatments in rehabilitation settings, wellness centres, and dedicated therapy pools.

🔄 Upgrade from Underpowered Blowers When existing 500W or 700W blowers fail to deliver sufficient airflow for larger jet systems, the G90-2AN-S provides a direct upgrade path. The standard 1.5″ BSP connection and compact dimensions ensure compatibility while delivering significantly improved performance.

🏠 Luxury Residential Spas Homeowners with larger spa installations appreciate the G90-2AN-S’s ability to power extensive air jet systems without compromise. The pneumatic control integrates seamlessly with traditional air button systems favoured in high-end residential applications.

🔌 Variable Speed System Potential For installations requiring adjustable airflow, this blower’s compatibility with external speed controllers offers flexibility. Start with standard pneumatic operation and add variable control later without replacing the blower unit.

🛠️ Installation Considerations

⚠️ Professional installation by a qualified electrician is essential

Electrical Requirements:

• Supply voltage: 230-240V AC, 50Hz
• Current draw: Approximately 3.9A
• Cable: 1m bare-end supply cord provided
• Wire colours comply with EN60335-2-60 (Brown = Live, Blue = Neutral, Yellow/Green = Earth for Class I units)
• Installation must include a fixed wiring switch with minimum 3mm contact separation in each pole

Mounting Position:

• Suitable for mounting below whirlpools and spas
• Secure using three screws through the integrated rubber feet
• Must not be accessible to bathers without use of tools
• Position must be protected from flooding
• Ensure location allows future access for inspection and maintenance

Ventilation Requirements:

• Install in a well-ventilated location
• Avoid cold air intake as this causes cold air injection into the bath water
• For warmer air output, position near pumps, heaters, or other warm spa components where possible

Plumbing Connections:

• Outlet: Rotatable 1.5″ BSP union with 32mm tail-piece (included)
• Pneumatic tubing: 3mm internal diameter flexible tubing required for air switch connection

⚠️ Critical Water Protection: Install either a double air loop with one check valve, OR two check valves, positioned above maximum water level to prevent water backflow into the blower. Water contact with the blower must be avoided at all times.

Variable Speed Control: If connected to an external variable speed control box, ensure the blower runs at high speed for a minimum of 5 seconds at startup.

Thermal Protection Note: If the thermal protection activates, the blower will not restart until power is disconnected and reconnected AFTER the unit has cooled to room temperature.

Maintenance: No special maintenance required. The intake filter can be cleaned by removing the two screws at the rear of the blower to access the base.
