116PSI /8Bar
GTX-778 delivers a maximum output pressure of 116 PSI, easily supporting multiple airbrushes at once. With the AirHub Pro, a single output expands into four, turning the airbrush holder into a powerful extension of the GTX-778. Each of the four outlets comes with its own PSI regulator, letting you connect all your airbrushes simultaneously - switch freely and create without limits.
Multi-Purpose Powerhouse
With its strong power, the GTX-778 not only handles airbrushes with ease but also drives various pneumatic tools. We tested it with an air drill, nail gun, and dremel, and the results were stable and impressive. It’s not just an airbrush compressor - it’s a true multi-purpose machine.
6L Large-Capacity Air Tank
Equipped with a large 6L air tank, it lets you spray longer without frequent refills.
How long does repressurizing take?
When the air runs out, how long can you keep spraying before repressurizing? We tested this with a GHPM-Mobius 0.3mm airbrush at 15 PSI, and it lasted up to 9 minutes of continuous airbrushing. While not a typical use case, it proves just how powerful it is.
From 3 bar to 8 bar - how fast? How long does it take?
We know the GTX-778 can refill air from 3 bar to 8 bar. But how long does it take? We tested this as well. Watch closely - it completes the job in just 45 seconds. Even we were impressed! Notice the glass of water we placed nearby? That’s because, while testing refill duration, we also measured vibration. And you can see the results for yourself.
Ultra Quiet
What you’re seeing now is the actual sound of the compressor, recorded directly through the microphone. In our studio, less than a meter away, the average noise level is just over 50 dB. For comparison, here’s the sound of a typical office environment - with background noise like typing, a coffee machine, microwave, and casual conversations.
