An apparatus for purging an article such as a tire of moisture and other impurities and for inflating the article with dry pure gas. The apparatus includes a four way valve; a gas input assembly communicatively connected to the valve; a vacuum generator communicatively connected to the valve; and an article interface assembly communicatively connected to the valve. A method of purging and inflating an article, includes the steps of establishing fluid communication between an article and a valve; establishing a pressurized fluid communication between the valve and a source of pressurized gas; establishing a fluid connection between the valve and a vacuum generator whereby pressurized gas flows through the vacuum generator to the atmosphere and fluid in the article flows through the vacuum generator to the atmosphere; and establishing a fluid connection via the valve whereby pressurized gas flows to the article.
