Try this:

Declare an attribute of type DefaultStreamedContent in your bean: Example:

private DefaultStreamedContent download;

Do the Get and Sets:

public DefaultStreamedContent getDownload() {
        return download;
    }

public void setDownload(DefaultStreamedContent download) {
        this.download = download;
}

Next :

    //Método que faz o download do anexo
    public void prepDownload() throws Exception {
        File file = new File("c:/tmp/arquivo.pdf");

        InputStream input = new FileInputStream(file);
        ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
        setDownload(new DefaultStreamedContent(input, externalContext.getMimeType(file.getName()), file.getName()));
    }

Then on your button;

<p:commandButton icon="ui-icon-arrowthickstop-1-s"
    title="Download Anexo"
    actionListener="#{bean.prepDownload()}"
    ajax="false">
    <p:fileDownload value="#{bean.download}" />
</p:commandButton>
