Product Questions
Why does the compressor keep running?
The GT-918 should normally stop the motor when tank pressure reaches approximately 57 PSI. If it continues running without reaching the shut-off point, check for major air leaks. If no leak is found, stop the unit and contact support to inspect the pressure-control system.

Product Questions
Why does the GT-918 not build pressure?
Check for an open tank drain, loose hose or outlet connections, or significant air leaks. Make sure all valves and fittings are correctly closed or connected. If the compressor still cannot build pressure, stop using it and contact Gaahleri support.

Product Questions
Does the tank reduce vibration or noise?
The air tank primarily helps stabilize airflow and reduce motor cycling. The GT-918 also uses rubberized feet to help minimize vibration and improve stability during operation.

Product Questions
How noisy is the GT-918 compared to smaller compressors?
Operating at roughly 50 dB it is remarkably quiet. Because the motor turns off while spraying from the 1L tank, it is silent for much of your painting session.

Product Questions
Can multiple airbrushes be connected?
Yes. The GT-918 has two independent air outlets and can run two airbrushes simultaneously. A manifold such as the AirHub Pro can provide additional connection points, but total airflow demand must still remain within the compressor’s capacity.

Product Questions
How does the tank affect performance?
The 1L tank acts as an air buffer, helping smooth airflow and reduce frequent motor cycling. It also allows some compressed air to cool and moisture to condense before reaching the air line. The motor can rest while stored air is being used.
