A thread in Marketplace got me thinking about the operating pressure of my old Clisby compressor. I have no idea what the condition of the tank is and it seems it is quite expensive to have the tank tested. Currently the compressor cuts out when the tank pressure is 130psi. I rarely use more than 40 psi for spray painting and tyre inflation. I use a thin 10m hose for painting and I need about 60psi at the regulator to achieve 40psi at the gun.

Would it prudent to drop the cutout pressure to something lower than 130psi to reduce the stress on the tank? Obviously I will lose air capacity by doing this, but I doubt I need the full 130psi for my purposes. I'm assuming my cutout switch is adjustable.

What pressure do your compressor tanks run at?
Any thoughts on my idea?
