Gaahleri GTX-778 – Precision Meets Quiet
The GTX-778 airbrush compressor from Gaahleri's Apex Force series is a semi-industrial high-performance compressor for demanding artists, model makers, and designers.
It impresses with powerful performance, ultra-quiet operation, and sophisticated functionality that noticeably improve your workflow.
Power & Precision
With a maximum pressure of 8 bar (116 PSI), the GTX-778 delivers sufficient power for virtually all airbrush and pneumatic tools.
The robust motor fully fills the pressure tank in just 45 seconds, providing consistent air pressure at all times – for precise, uninterrupted work.
Dual Air Outlet System
The innovative dual-port system allows you to connect up to four airbrush guns simultaneously.
Whether you use different tools in parallel or work with multiple artists or students – the GTX-778 flexibly adapts to your working style.
Intelligent start-stop technology
The Smart Stop function ensures efficiency and longevity.
The compressor activates automatically between 3–8 kg/cm², protecting the motor and reducing energy consumption and noise.
Quiet & low-vibration
Thanks to its Ultra-Silent technology, the GTX-778 operates particularly quietly – ideal for use in studios, homes, or educational institutions.
For additional dampening, we recommend a soft surface (e.g., a foam mat or blanket) to minimize vibrations.
Precise Pressure Monitoring
A shock-resistant hydraulic pressure gauge allows precise control of the working pressure in real time. This way, you always maintain full control of your airbrush applications.
Maintenance & Care
Before first use, the compressor should be filled with 200 ml of refrigeration oil (pre-filled in some regions).
The oil should be changed every 200 hours of operation to ensure optimal performance and longevity.
Turn off the unit after use and regularly drain condensate from the tank and filter.
