Abstract:
1. A gas panel for use with a gas source, a compressed air source and a chamber, the gas source being operable to provide a flow of gas, the compressed air source being operable to provide a flow of compressed air, said gas panel comprising: a first gas supply line arranged to receive gas from the gas source; a compressed air supply line arranged to receive compressed air from the compressed air source; a mass flow controller operable to receive the gas via said first gas supply line and to provide a controllable output flow of the gas; a valve operable to be in a first state and a second state, to pass a first amount of the flow of the gas into the chamber when in the first state and to pass a second amount of the flow of the gas into the chamber when in the second state; an exhaust portion operable to remove a portion of the flow of the gas when not passed into the chamber when said valve is in the first state, wherein the portion of the flow of gas is not passed into the chamber when a broken line is present between the mass flow controller and the valve; a nozzle positioned between the mass flow controller and the valve and operable to receive the compressed air via said compressed air supply line; a housing; a gas detector operable to detect a presence of the gas within said housing when the gas is present in said housing; and a compressed air controller operable to control an amount of compressed air provided by said nozzle based on an amount of gas detected by said gas detector; wherein said first gas supply line, said compressed air supply line, said mass flow controller, said valve and said nozzle are disposed within said housing, and wherein said nozzle is operable to provide an output flow of the compressed air within said housing to provide a flow of the portion of the flow of the gas that is not passed into the chamber when said valve is in the first state.
