PURPOSE: A gas removal device of a hot runner system is provided to push out gas by supplying compressed air to the hollow portion of a space ring. CONSTITUTION: A gas removal device of a hot runner system comprises an air supply pipe(96), air flow pipes(92, 93), a second solenoid valve(95), and an air supply path(16). The air supply pipe supplies compressed air discharged through air channels(11, 12) to a clamping plate(10). The air flow pipes connect the air supply pipe to the air channels. The second solenoid valve is connected to one of the air flow pipes. The air supply path is formed in the clamping plate and connects the air supply pipe to a space ring(80). Gas accumulated in the hollow portion of the space ring is pushed back by the compressed air supplied through the air supply pipe and is discharged to the outside.
