Is prestone coolant g-05 equivalent?

IDK much about coolant. But my hatsan lighting compressor recommend G-05 or equivalent coolant. I used prestone 50/50 in my car. So still have some left. But doesn't say G-05 on the label. Are prestone coolant g-05 or equivalent? Im using distilled water on my compressor right now but want to use coolant to prevent rust or corrosion. Will keep compressor in the house, so temp will never drop to freezing point. Is distilled better or should I switch to coolant if I want my compressor to last a long time.
