G.A.S SonicAir Pro Humidifier - High-Output Ultrasonic Humidifier with Continuous Water Feed
Best for: growers with larger rooms needing high, sustained humidity output without the hassle of constantly refilling a tank.
Our thoughts
The continuous water feed is the real selling point here - instead of topping up a tank, the SonicAir Pro connects to a header tank and just runs. Ten ceramic ultrasonic disks pushing out 6.5 litres of mist an hour is a serious amount of humidity for a larger space, and the 360-degree outlet means you can actually aim it where you need it, or duct it entirely with 150mm ducting.
The G.A.S SonicAir Pro Humidifier from Global Air Supplies is built for larger grow rooms that need more humidity than a tank-fed unit can sustainably deliver. It uses 10 ultrasonic ceramic disks to turn RO water into a fine mist, producing up to 6.5 litres of mist per hour - considerably more than the standard SonicAir's 800ml per hour.
Rather than a fill-and-monitor tank, the SonicAir Pro takes a water intake connection, so it's fully compatible with header tanks and can run for weeks with minimal hands-on attention. The mist is directed out through a funnel that rotates a full 360 degrees, so you can aim it at a specific low-humidity area, or connect 150mm ducting for more precise placement across a larger room. It draws 300W and runs at under 35dB, and includes an automatic shut-down feature that protects the ceramic disks if the unit ever runs dry.
How it compares
The SonicAir Pro is positioned as the high-output option in G.A.S's humidifier range.
- Versus the standard G.A.S SonicAir Humidifier: the Pro's 6.5 litres per hour output is around eight times the standard model's, aimed at rooms that need genuine sustained humidity rather than a top-up.
- Versus AC Infinity's CloudForge range: AC Infinity's units bring app-based VPD scheduling to smaller reservoirs; the SonicAir Pro trades that connectivity for raw output and continuous water feed suited to bigger spaces.
- Versus a domestic ultrasonic humidifier: household units aren't built for continuous water-fed operation or ducting connections the way the SonicAir Pro is.
If your room's humidity needs outgrow a tank-fed unit, the SonicAir Pro's continuous feed and higher output are the reason to step up to it.
Usage guidance
The SonicAir Pro is designed for long-term, low-maintenance operation once installed.
Water supply
Connect to a header tank using RO water for continuous operation without manual refilling.
Directing mist
Rotate the outlet funnel to aim mist at a specific low-humidity area, or connect 150mm ducting to distribute it further into the room.
Automatic control
Pair with a G.A.S Intelligent Humidity/VPD Controller for SonicAir Pro to switch it on and off automatically based on humidity or VPD targets rather than running it continuously.
Maintenance
The ceramic ultrasonic disks are replaceable, and automatic shut-down protects them if the water supply runs out.

Who this is for

- Growers running ducted humidity distribution rather than a single-point spout
Best suited to bigger grow spaces where a tank-fed humidifier would need constant topping up.
Our take
The SonicAir Pro is built for growers who've outgrown tank-fed humidifiers - the continuous feed and 6.5L/hour output solve the maintenance headache that comes with running a larger room's humidity manually.
If your space needs genuine sustained humidity rather than a quick top-up, this is proper kit that does exactly what it should, day in, day out.
