Hi,
I have this compressor…

and connected a air tank extension…

On the tank extension. The max pressure it can hold is around 87psi.
The compressor max pressure is around 60psi.
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!
“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
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

Thanks Pawel. Will build up the courage on removing the cover for the pressure switch. Will update you. Cheers.
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
