Theoretically you can by compressing normal air to a tank, then you will have a full tank with a 8 bar pressure, then find another tank, do it again as you do with the first tank, and now you have two tanks with same 8 bar pressure.
Now connect one of those tank to the inlet of the compressor and the other to the outlet of the compressor. Run the compressor, and you will get the tank that connected to the outlet of the compressor a higher pressure than 8 bar. Do it repetitively and by the end you will have a tank with 200 bar pressure.
This technique is used in multistage compressor.
But practically don't do this. Why ? A compressor is designed with a working pressure. and of course has limitation on strength.
a 8 bar compressor is much less weaker than 200 bar compressor, so with the tanks, a 8 bar tank is much weaker than 200 bar tank.

A typical compressor will have a pump and a storage vessel. if the pump is a positive displacement pump such as a piston pump it will continue to pressurize the storage vessel until the vessel breaks. This can be very dangerous as 1 bar is rough;y equal to 14.7 psi or 1 atmosphere so 200 bar is almost 3000 psi. I hope your storage vessel if there is one is made out of thick steel like a scuba tank.

You can use a pressure multiplier, which takes your 8 bar air, applies it to a large piston connected to a small piston. The small piston compresses the air in its cylinder to a pressure equal to the input pressure * the ratio of the piston areas.

Well, I don't think you can. If you do, either your gage is messed up or your compressor is about to blow up.
