Smile How Sufficient is Vacuum Pump made from 1.5 Ton AC Compressor

Hello Everyone,

I started learning ac repair and converted my Samsung Ac 1.5 Ton Rotary Compressor into vacuum pump.

I would like to know is it sufficient for pulling air and moisture from the system?
It become very hot when pulling vacuum for more than 20 minutes ?

It is not sufficient.
Compressors are cooled via refrigerant vapor. When no refrigerant is flowing they quickly overheat.
They will also not provide low enough vacuum to properly evacuate the system.

A vacuum pump for A/C work uses rotary carbon vanes for maximum suction power.
