Product Questions

Why is pressure inconsistent?

Make sure the compressor can provide enough pressure and airflow for the highest-demand airbrush connected to the hub. Check the main air supply for pressure fluctuations or leaks, then verify each AirHub Pro outlet regulator is correctly adjusted.

Product Questions

Why is there air leakage at the connections?

Check that the fittings are correctly seated and tightened, and inspect any seals or O-rings used by the connection. If a threaded fitting requires thread sealant, use only a suitable sealing method for that fitting rather than automatically applying PTFE tape to every connection.

Product Questions

Why is air not flowing through one outlet?

Check that the pressure regulator for that outlet is open and correctly adjusted. Also inspect the connected hose and fittings for a loose connection, blockage, or leak.

Product Questions

Does it help maintain consistent air pressure?

The AirHub Pro provides independent pressure control for each connected airbrush. However, overall pressure stability still depends on the compressor, airflow demand, hose condition, and upstream air supply.

Product Questions

Can I control airflow for each airbrush?

Yes. The AirHub Pro has four independent pressure regulators, allowing each connected airbrush to use its own pressure setting.

Product Questions

Does the AirHub Pro affect air pressure?

The AirHub Pro allows independent pressure adjustment at each outlet. If several airbrushes spray simultaneously, total airflow demand increases. If that demand exceeds the compressor’s capacity, working pressure at one or more outlets may drop.

Product Questions

Can I switch between airbrushes without disconnecting hoses?

Yes. Multiple airbrushes can remain connected to the AirHub Pro, allowing you to switch between them without repeatedly disconnecting the main air lines. Each outlet has its own pressure control.

Product Questions

How do I connect multiple airbrushes?

Attach individual air hoses (or quick-disconnect lines) from each of the AirHub Pro’s outlet ports directly to your respective airbrushes.
