The flow divider is configured to divide the initial gas flow into a first flow of gas and a second flow of gas. The flow divider includes a first compartment including a first gas flow path for the first flow of gas and a second compartment including a second gas flow path for the second flow of gas. A heater is disposed in the second compartment. A method for use in generating breathing gas and insulating gas from a gas source is also disclosed.
