🌀 CG Air 900 Watt Heated Air Blower (SLO-3-90) | 1.2HP with 300W Ceramic Heater — Premium Warm Air Bubble Massage

Experience the ultimate in hot tub luxury with pre-warmed air bubbles — this powerful 1200W combined output blower with integrated ceramic heater delivers soothing, body-temperature bubble massage for unparalleled comfort.

ℹ️ Product Overview

The CG Air 900 Watt Heated Air Blower represents the premium choice for discerning hot tub owners who refuse to compromise on comfort. Manufactured by CG Air Systèmes inc. in Canada, this high-performance blower combines a powerful 1.2HP motor with an integrated 300W ceramic heating element that pre-warms the air to body temperature before it enters your spa water.

Unlike non-heated blowers that can introduce cool air and cause uncomfortable chilling sensations, the SLO-3-90 ensures every bubble that rises through your spa water is comfortably warm. This eliminates the “cold air effect” that many bathers experience — that shivering sensation caused by cool bubbles running across wet skin — even when the spa water itself is at the perfect temperature.

Pre-installed on numerous North American spa brands including Sunrise Spas, this robust unit features integrated thermal protection in the heating element, anti-vibration plates with rubber pins for quiet operation, and long-life motor brushes rated for approximately 1,500 hours of domestic use. The 1.5-inch socket connection ensures compatibility with most existing spa plumbing, making it an ideal upgrade or replacement choice for spa owners seeking the ultimate hydrotherapy experience.

🏠 Real-World Applications

🛁 Premium Residential Hot Tubs

The heated blower is the ultimate upgrade for home spa owners who use their hot tub year-round, especially in cooler climates. The 300W ceramic heater ensures comfortable bubble temperature even during autumn and winter evenings when ambient air is cold. No more goosebumps or shivers — just pure relaxation from the moment you activate the bubble massage.

💆 Therapeutic Hydrotherapy Sessions

For those using their spa for genuine therapeutic benefit — whether for muscle recovery, arthritis relief, or stress management — the warm air bubbles provide enhanced comfort during longer hydrotherapy sessions. The consistent body-temperature air eliminates temperature shock, allowing you to focus entirely on the therapeutic massage effect.

♨️ Outdoor & Exposed Installations

Hot tubs positioned in exposed locations, on decks, or in open gardens benefit significantly from heated blowers. Where a non-heated unit would draw cold outdoor air directly into the spa, the SLO-3-90’s ceramic heater pre-warms this air to comfortable levels, maintaining the luxurious spa experience regardless of ambient conditions.

🔄 Blower Replacement & Upgrades

This unit serves as a direct replacement for worn or failed heated blowers on Sunrise Spas (part numbers R5021605 AMP, R5021604 in.link), Canadian Spa Company, and other North American-manufactured spas. It’s also an excellent upgrade from non-heated models for owners seeking enhanced comfort. The standardised connections ensure straightforward retrofit installation.

🏨 Holiday Properties & Rental Accommodation

Owners of rental properties with hot tub amenities choose heated blowers to maximise guest satisfaction. The improved comfort level translates to better reviews and repeat bookings. The 1,500-hour rated motor life and robust construction handle regular guest use reliably.

🏢 Boutique Spas & Wellness Centres

Smaller commercial wellness facilities appreciate the enhanced client experience that heated air massage provides. The integrated thermal protection ensures safe, reliable operation for regular professional use, whilst the quiet operation maintains the tranquil atmosphere essential for spa environments.

🛠️ Installation Considerations

⚠️ Professional Installation Recommended

Due to the combined electrical requirements of the motor and heating element, we strongly recommend installation by a qualified electrician or spa technician.

⚡ Electrical Requirements

• Supply Voltage: 230V AC, 50Hz
• Current Draw: 5.5 – 6.0 Amps (higher than non-heated models due to heating element)
• Circuit Protection: Class A Ground Fault Interrupter (GFI/RCD) required
• Wiring: Permanent installation required — do not use extension cords
• Connection: J&J cord supplied; adaptable to AMP or in.link connections

📐 Positioning & Ventilation

• Blower must NOT be insulated — requires surrounding airspace for proper cooling
• Maintain minimum 30″ × 15″ (75cm × 40cm) access panel near blower for servicing
• Ensure adequate ventilation around the unit for the heating element to function safely
• Clean installation area thoroughly before fitting to prevent debris entering the air inlet

🔗 Plumbing Connections

• Outlet: 1.5″ (48mm) smooth socket — slip-fits into standard spa hose
• No glue required: Simple push-fit connection; secure with hose clamp or screw if needed
• Check Valve: ESSENTIAL — install air check valve between blower and jets to prevent water backflow
• Goose-neck loop: Position air pipe above water level before entering spa for additional backflow protection

🛡️ Critical Safety Points

• Always verify spa pack pin-out diagram before wiring
• Match voltage rating exactly (230V model — do not use on 120V systems)
• The heating element will NOT reheat your spa water — it only pre-warms the incoming air to body temperature
• Install GFI/RCD protection as per local electrical codes
• Water temperature should not exceed 40°C (104°F) during use
• Warranty void if water enters the blower — always install check valve

🌡️ Understanding the Heater Function

The 300W ceramic heating element warms the air to approximately body temperature (around 37°C) as it passes through the blower. This prevents the “cold air effect” where bubbles running along wet skin cause a shivering sensation — even when the spa water is hot. The heater is NOT designed to heat your spa water; this remains the job of your spa’s main heating system.

Considerations when replacing a blower

  When replacing a hot tub blower, there are a few important factors to consider. One of the most important considerations is ensuring that the voltage of the replacement blower matches the voltage of your hot tub’s electrical system. This is because using a blower with the wrong voltage can result in damage to the blower, the hot tub’s electrical system, or both. Check if the blower you are replacing is 230V or 120V – it makes a difference!   While the power of the blower is not necessarily important, it’s a good idea to select a replacement blower that has a similar power rating to your existing blower. This will help ensure that the replacement blower is capable of producing the desired air pressure and flow rate in your hot tub.   Another factor to consider when replacing a blower is the size of the blower’s outlet pipes. If the replacement blower has different pipe sizes than your existing blower, you may need to use adaptors or convertors to connect the blower to your hot tub’s plumbing. This is important to ensure that the blower is properly connected and doesn’t leak air.   In summary, when replacing a hot tub blower, it’s important to match the voltage of the replacement blower to your hot tub’s electrical system and consider the power rating and pipe sizes of the replacement blower. By selecting a replacement blower that matches these criteria and ensuring that it’s properly installed, you can help ensure that your hot tub continues to provide a relaxing and enjoyable experience.  

Don’t forget the Check Valve!

  A check valve is an important component to consider when installing a hot tub blower. A check valve is a one-way valve that allows water to flow in one direction only, preventing backflow. In a hot tub, the check valve is typically installed on the air line between the blower and the jets. This keeps the water out of your blower – last thing you want is water in your blower. There are a few reasons why a check valve is important when using a hot tub blower:

1. Prevents water from entering the blower: Without a check valve, water can backflow from the hot tub plumbing into the blower when the blower is turned off. This can cause damage to the blower and can also create a safety hazard if water comes into contact with the blower’s electrical components.
2. Maintains air pressure: A check valve helps maintain the proper air pressure in the hot tub system. Without a check valve, air can escape from the hot tub jets when the blower is turned off, reducing the water pressure and the effectiveness of the massage feature.
3. Reduces noise: A check valve can help reduce noise in the hot tub plumbing system. When the blower is turned off, water can flow backwards through the air line and create a gurgling or burping noise. A check valve prevents this noise from occurring.

In summary, a check valve is an important component to consider when installing a hot tub blower. It helps prevent water from entering the blower, maintains air pressure, and reduces noise in the plumbing system. By including a check valve in your hot tub blower installation, you can help ensure that your hot tub runs smoothly and efficiently.  

Wiring a Hot Tub Blower

          When wiring a hot tub blower, it’s important to not only follow the manufacturer’s instructions but also to check the pin out diagram on the spa pack. The pin out diagram will show you the location of the various terminals and connectors on the spa pack, which you’ll need to connect to the blower. Here are the steps to wire a hot tub blower while checking the pin out diagram on the spa pack:

1. Turn off the power to the hot tub at the circuit breaker.
2. Locate the spa pack, which is usually located near the hot tub. Look for the pin out diagram, which should be located on the inside of the access panel.
3. Determine the voltage requirements of the blower. Most hot tub blowers operate on 120 volts, but some may require 240 volts. Make sure you have the correct voltage before proceeding.
4. Connect the blower to the control system. The blower should have a set of wires that connect to the spa pack. Match the wires from the blower to the corresponding terminals on the pin out diagram. Make sure to follow the manufacturer’s instructions for the proper wiring sequence.
5. Connect the blower to the power source. The power source is usually a dedicated GFCI breaker or a GFCI outlet that is installed near the hot tub. Again, follow the manufacturer’s instructions and match the wires from the power source to the corresponding terminals on the pin out diagram.
6. Test the blower to make sure it’s working properly. Turn on the power to the hot tub and activate the blower from the control panel. The blower should start up and produce the desired amount of air.
7. Secure all wiring connections and close the access panel to the spa pack.
8. Turn on the power to the hot tub at the circuit breaker.
