SonicAir Pro Humidifier With Float Valve

The SonicAir Pro Humidifier With Float Valve from Global Air Supplies (G.A.S) is a professional, high capacity ultrasonic grow room humidifier designed to deliver powerful and consistent humidity control for hydroponic grow rooms, indoor growing environments, greenhouses, propagation rooms and commercial horticultural applications. With an impressive maximum mist output of 6.5 litres per hour, the SonicAir Pro is an excellent solution for growers who need to increase atmospheric moisture and maintain a stable growing environment.

Maintaining the correct relative humidity (RH) is an important part of successful indoor cultivation. Humidity influences plant transpiration, water movement and the surrounding growing climate. When humidity levels become too low, plants can lose moisture more rapidly, potentially increasing environmental stress. The G.A.S SonicAir Pro Humidifier helps growers manage these conditions by producing a continuous supply of fine, cool water mist that can be distributed throughout the growing area.

Powered by 10 ultrasonic ceramic discs, the SonicAir Pro transforms water into a fine mist without relying on a conventional heating element. Its integrated fan pushes the mist through a 150mm directional outlet, allowing moisture to be directed towards areas requiring additional humidity. The outlet can also be connected to compatible 150mm ducting for more flexible distribution around larger growing spaces.

One of the most useful features of the SonicAir Pro Humidifier With Float Valve is its automatic water replenishment system. Unlike traditional humidifiers that require frequent manual refilling, the SonicAir Pro connects directly to an external water reservoir or header tank. Its built in automatic float valve maintains the internal water level, helping reduce maintenance and making the unit particularly suitable for demanding growing environments.

Designed with reliability and ease of maintenance in mind, the SonicAir Pro includes automatic low water protection, a visual water level warning indicator, replaceable ultrasonic discs, an overflow connection and a convenient drain plug. It can operate independently or be connected to a compatible G.A.S Intelligent Humidity Controller for automated environmental management.

Whether you are maintaining humidity in a large hydroponic grow room, supporting young plants in a propagation area or upgrading your existing grow room climate control system, the SonicAir Pro 6.5L Humidifier offers a practical combination of powerful mist production, automatic water management and efficient ultrasonic technology.

Specifications

Who It's For

The G.A.S SonicAir Pro Humidifier With Float Valve is ideal for growers who require a powerful, dependable and relatively low maintenance hydroponic humidifier. Its substantial 6.5 litre per hour mist output makes it particularly useful in larger growing environments where smaller domestic humidifiers may struggle to provide sufficient moisture.

For hydroponic growers, maintaining suitable humidity levels can be an important part of achieving a balanced indoor growing climate. The SonicAir Pro can be used alongside extraction fans, circulation fans, heating equipment and environmental controllers to help manage moisture levels throughout the growing area.

In plant propagation rooms, young plants and cuttings may benefit from higher relative humidity during establishment. The SonicAir Pro allows growers to introduce additional atmospheric moisture while using a compatible controller to manage humidity according to their propagation requirements.

For vegetative growth environments, the humidifier can help compensate for dry incoming air or moisture removed by ventilation equipment. By increasing relative humidity when required, growers can manage the surrounding climate more effectively.

During flowering and fruiting, humidity requirements may change depending on plant species, growth stage and environmental conditions. When combined with suitable monitoring and ventilation equipment, the SonicAir Pro can provide controlled humidification as part of a wider climate management strategy.

The unit is also suitable for greenhouses, specialist horticultural rooms, orchid growing environments and mushroom cultivation facilities where additional atmospheric moisture may be required.

Its automatic water supply makes the SonicAir Pro especially attractive to growers who want to reduce the time spent manually refilling equipment. By connecting the humidifier to a suitable header tank, the internal float valve can regulate incoming water, allowing the system to operate with less frequent intervention.

For growers developing a more advanced automated grow room, the SonicAir Pro can be combined with a compatible G.A.S controller to respond to changes in relative humidity. This makes it a practical addition to larger indoor horticultural installations where consistency, reliability and ease of maintenance are important.

How To Use

Installing the SonicAir Pro Humidifier With Float Valve is straightforward when connected to a suitable water supply and correctly positioned within the growing environment. For the best results, follow the manufacturer's installation instructions and ensure the humidifier is appropriately matched to the size and humidity requirements of your growing area.

Step 1: Position the Humidifier

Place the SonicAir Pro on a stable, level surface within your grow room, greenhouse or propagation area. Choose a location that allows the mist to circulate effectively without directly saturating electrical equipment, plants or surrounding surfaces. Positioning the humidifier near the air intake area can help distribute moisture through the growing environment.

Step 2: Connect the Water Supply

Connect a suitable external water reservoir or header tank to the humidifier's water inlet using the appropriate hose and connection fittings. Once the water supply is opened, the internal automatic float valve regulates the incoming water and maintains the required operating level.

Ensure all water connections are secure and check for leaks before operating the humidifier. The external reservoir should be installed in accordance with the manufacturer's water supply requirements.

Step 3: Use Reverse Osmosis Water

For optimum performance, fill the external reservoir with reverse osmosis (RO) water. RO water contains fewer dissolved minerals than untreated tap water, helping reduce deposits on the ultrasonic ceramic discs and minimise mineral residue released with the mist.

Using the recommended water quality also helps maintain the humidifier's performance and is important for compliance with the manufacturer's warranty conditions.

Step 4: Adjust the Mist Outlet

Fit the supplied 150mm directional outlet funnel and rotate it towards the area requiring additional humidity. The adjustable outlet allows growers to direct mist more precisely within the growing environment.

Where necessary, compatible 150mm ducting can be connected to distribute mist to another location. Ensure any ducting arrangement allows moisture to move effectively without creating excessive condensation or water accumulation.

Step 5: Connect the Power Supply

Connect the humidifier to a suitable electrical supply using its UK mains plug. Ensure the power connection is protected from moisture and that all electrical equipment is installed safely in accordance with the manufacturer's instructions.

Once the unit is switched on and the correct water level has been established, the 10 ultrasonic ceramic discs generate a fine mist. The integrated fan then moves the mist through the directional outlet and into the surrounding environment.

Step 6: Set Up Automatic Humidity Control

For more precise operation, connect the SonicAir Pro to a compatible G.A.S Intelligent Humidity Controller. Follow the controller's instructions to configure the required relative humidity settings and position its humidity sensor appropriately.

The controller can then manage humidifier operation in response to the measured humidity level, helping maintain a more consistent growing environment without relying entirely on manual switching.

Step 7: Monitor Relative Humidity and VPD

Use a suitable hygrometer or environmental controller to monitor relative humidity (RH) and temperature within the growing area. Growers using vapour pressure deficit (VPD) as part of their climate management strategy can use these measurements to assess whether additional humidification is required.

The appropriate humidity level will depend on the plant species, growth stage, temperature, ventilation rate and overall growing conditions. Avoid excessive humidification, as prolonged high humidity and condensation can increase the risk of moisture related problems.

Step 8: Check Water Levels and Safety Features

The SonicAir Pro includes a built in low water warning indicator that illuminates red when the internal water level becomes insufficient. If the water level falls too far, the automatic shut off system stops operation to help protect the ultrasonic discs and fan.

Regularly inspect the external reservoir, water supply connections, float valve and overflow outlet to ensure the system continues operating correctly.

Step 9: Clean and Maintain the Humidifier

Disconnect the humidifier from its electrical supply before carrying out cleaning or maintenance. Use the integrated drain plug to empty the unit when required, and clean the internal water contact areas in accordance with the manufacturer's instructions.

Inspect the ultrasonic ceramic discs for mineral deposits, wear or reduced mist production. Replacement discs are available to help maintain performance and extend the usable life of the humidifier.

Keeping the water supply clean and maintaining the ultrasonic components will help support consistent mist output and reliable long term operation.

Important: The SonicAir Pro requires an external water supply and should be operated using the water quality specified by the manufacturer. Always ensure the overflow is managed safely, avoid placing electrical equipment in the path of the mist and follow the manufacturer's instructions for installation, cleaning and maintenance.
