💨 HydroAir Balboa Genesis Air Blower – G90-2HN-S (900W + 250W Heater, Electronic On/Off)

High-performance 1150W heated air blower delivering warm, invigorating bubbles for medium to large hot tubs – no cold air bursts

📝 Product Overview

The HydroAir Balboa Genesis G90-2HN-S represents the premium tier of the Genesis air blower range, combining a powerful 900W motor with an integrated 250W heating element for a total output of 1150W. This combination delivers what spa enthusiasts truly want: warm, comfortable bubbles without the shock of cold air bursts that can disrupt relaxation.

Designed for medium to large hot tubs and whirlpool baths supporting 8-15 air jets, the G90-2HN-S provides robust airflow of approximately 2,100 litres per minute at up to 2.4m head pressure. The electronic on/off control integrates seamlessly with spa control panels, while compatibility with external speed controllers offers the flexibility to tailor airflow intensity to personal preference.

The integrated heating element warms the air before it enters the water, eliminating the uncomfortable cold sensation that non-heated blowers can produce – particularly noticeable during cooler months or extended bathing sessions. This warm airflow enhances the overall hydrotherapy experience, making bubble massage genuinely relaxing rather than startlingly cold.

Housed in HydroAir’s signature robust blue polypropylene casing with IPX5 water-resistant protection, this blower is manufactured by HydroAir, a division of Balboa Water Group, according to European norms EN60335-1 with focus on EN60335-2-60. The automatic dry-out safety feature protects internal components by cycling the blower after use, extending operational lifespan.

🏠 Real World Applications

♨️ Premium Hot Tub Installations The G90-2HN-S is the choice for discerning hot tub owners who refuse to compromise on comfort. The heated airflow ensures bubbles feel warm and soothing rather than shockingly cold, transforming the bathing experience – particularly during autumn and winter months when the temperature contrast would otherwise be most noticeable.

🛁 Luxury Whirlpool Bath Systems High-end whirlpool baths with 8-15 air jets benefit from both the powerful airflow and warm air delivery. The electronic control integrates with bathroom control panels for sophisticated operation, while the heating element ensures consistent comfort throughout extended bathing sessions.

💆 Hydrotherapy & Wellness Centres Professional wellness installations demand heated airflow for client comfort. Cold air bursts are unacceptable in therapeutic settings – the G90-2HN-S eliminates this issue entirely while providing the robust performance commercial applications require.

🏨 Hotel & Hospitality Spa Facilities Hotels and resorts choose heated blowers to ensure guest satisfaction. The automatic dry-out feature reduces maintenance requirements, while the durable construction handles the extended duty cycles typical in hospitality environments.

🔄 Upgrade from Non-Heated Blowers Owners disappointed by cold air bursts from existing non-heated blowers find the G90-2HN-S transforms their spa experience. The standard 1.5″ BSP connection ensures compatibility while the heating element addresses their primary complaint.

🌡️ Year-Round Outdoor Spa Use For outdoor hot tubs used throughout the year, heated airflow becomes essential during cooler seasons. The G90-2HN-S maintains comfortable bubble temperatures regardless of ambient conditions, extending the usable season of outdoor installations.

🛠️ Installation Considerations

⚠️ Professional installation by a qualified electrician is essential

Electrical Requirements:

• Supply voltage: 230-240V AC, 50Hz
• Current draw: Approximately 5A (with heater engaged)
• 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
• Ensure electrical supply can accommodate the full 1150W load

Control Integration:

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

Heater Operation:

• The heating element automatically switches off if air temperature rises above approximately 50°C
• Per EN 60335-2-60: when a heating element is built into the device, the water temperature at the inlet should not exceed 50°C

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
• The heating element supplements air temperature but draws ambient air – avoid extremely cold intake locations

Plumbing Connections:

• Outlet: Rotatable 1.5″ BSP × 32mm union (included)

⚠️ 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.

Automatic Dry-Out Function: The built-in timer triggers automatic shutdown after approximately 30 minutes of operation. Following shutdown, the blower will briefly restart to purge moisture from the system, protecting internal components.

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.
