The apparatus, for filling a flexible pouch having a bottom end, an opposite top end, and a pair of side edges extending between the bottom and top end, includes a filling station, a supply of compressed purging gas, and a gas purging station. The filling station includes a feeder that dispenses an amount of product into the pouch. The gas purge station is positioned subsequent to the filling station and includes a pair of gas lances. Each of the pair of gas lances have an outlet to discharge the purging gas into the pouch. The pair of gas lances being moveable between an inserted position and a withdrawn position. In the inserted position the pair of gas lances are disposed within the pouch a predetermined distance above the amount of product, and in the withdrawn position the pair of gas lances are provided above the top end of the pouch.
