Pressure Switch for Airbrush Compressor...

Pawel

Hello!

Can you show a photo of the pressure switch itself? Preferably with the housing off?

Hi Pawel. You can see the pressure switch is somewhat different from a big compressor.

Not sure yet how to open this. The bleed valve is rated 100psi just for your info.

Cheers

Hello!

Can you show a photo of the pressure switch itself? Preferably with the housing off? Usually it's a question of adjusting a screw on a spring to manipulate the pressure or pressures (on and off).

There's the safety valve - it's rated opening pressure should be stamped in the metal on it. It's usually much higher than the "off" pressure of the switch.

Hope it helps - have a nice day

"You could, but unless you need to pump tyres or run a nail gun, why would you?"

Just to max the extension tank capacity. Its only filled around 0.4+ MPa or 60 psi.

Then again theres the bleed valve. As you said, its designed to function on a certain pressure. I guest I just have to leave it as is since I'm not certain also with the bleed valve.

Thanks

My question is...

Can I adjust the compressor pressure switch to match the tank extension max pressure capacity? The bleed valve is another thing I need to figure out also.

You could, but unless you need to pump tyres or run a nail gun, why would you?

Typically, I run my Iwata HP-CS & Badger 4000, between 20-25 PSI, or up to 30-35 PSI when spraying Badger StyNylRes, & even my TRN-1 knock-off doesn't need 60PSI, so I can't think of a modelling reason to need 78PSI?

The Iwata compressor is a good bit of kit, & you will considerably shorten the service life if it if you run it over spec. It also has a handle as the tank, but connecting a tank is also a good idea, as the max pressure is higher than the compressor max.

It produces 36L/M which equates to 1.271328 cubic feet per minute, which is more than adequate to run an airbrush or two.

The Bleed valve is designed to prevent damage to a: the compressor, & b: preventing the tank exploding, I wouldn't mess, experiments will tend to hurt!
