🫧 HydroAir Balboa Genesis Air Blower – G90-2NN-S (900W, Non-Heated, Electronic On/Off)

Powerful 900W electronic air blower with spa pack integration – robust bubble performance for medium to large hot tubs

📋 Product Overview

The HydroAir Balboa Genesis G90-2NN-S is a high-powered 900W air blower engineered for medium to large hot tubs and whirlpool baths that demand serious airflow combined with modern electronic control. Housed in HydroAir’s signature durable blue polypropylene casing, this blower delivers robust bubble action through seamless integration with electronic spa control systems.

With approximately 1.21 HP of motor power, the G90-2NN-S provides the muscle needed for installations with 8-15 air jets where standard blowers fall short. The electronic on/off control connects directly to spa packs and control panels, enabling automated operation, programmable cycles, and touchpad activation – ideal for contemporary spa setups.

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 and complexity of an internal heating element.

For installations requiring adjustable airflow intensity, this blower is fully compatible with external variable speed controllers – offering an upgrade path without replacing the unit itself. The rotatable outlet union simplifies plumbing alignment, while the IPX5-rated housing ensures reliable operation in humid spa environments.

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.

🎯 Real World Applications

♨️ Medium to Large Hot Tub Systems The G90-2NN-S excels in hot tubs with 8-15 air jets where electronic spa packs control all functions from a central touchpad. The powerful 900W motor ensures consistent bubble pressure across all jets, while the electronic control enables programmable blower cycles and combination programmes with pumps.

🛁 Large Whirlpool Bath Installations Premium whirlpool baths with extensive jet configurations benefit from the G90-2NN-S’s enhanced capacity. The electronic control integrates with sophisticated bathroom control systems, while the robust motor maintains strong bubble action even with longer pipe runs.

🔌 Spa Pack Controlled Systems For installations where a central spa pack manages all equipment, this blower provides seamless integration. The electronic on/off design allows relay-controlled activation, enabling features like timed bubble cycles, combination pump/blower programmes, and touchpad operation.

🔄 High-Power Upgrade Projects When existing 500W or 700W blowers fail to deliver adequate airflow for larger jet systems, the G90-2NN-S provides a substantial upgrade. The standard 1.5″ BSP connection ensures compatibility while delivering significantly improved performance.

⚡ Variable Speed System Potential Owners seeking adjustable airflow can pair this blower with an external speed controller. This approach provides upgrade flexibility – start with basic on/off operation and add variable control later without replacing the blower unit.

🏢 Commercial & Rental Property Installations Holiday lets and rental properties with larger hot tubs benefit from the combination of powerful performance and spa pack integration. The electronic control enables simple operation for guests while the robust construction handles frequent use.

🛠️ 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
• Requires external spa controller or switch for operation

Control Integration:

• Connects to electronic spa packs via relay output
• Compatible with manual or programmable control interfaces
• Can be paired with external variable speed controllers for adjustable intensity
• If connected to external variable speed control, ensure blower runs at high speed for minimum 5 seconds at startup

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

Plumbing Connections:

• Outlet: Rotatable 1.5″ BSP union with 32mm tail-piece (included)

⚠️ Critical Water Protection: Installing a 32mm check valve is strongly recommended to prevent water ingress and eliminate gurgling sounds. Install either a double air loop with one check valve, OR two check valves, positioned above maximum water level.

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.
