Attach this hand pump to a Sanke 'S' keg, and you'll be able to serve beer without using any CO2.
Great for tailgating or camping, and very easy to use.
Be sure to finish off your keg within a few days, because when dispensing with air you run the risk of contamination.
Comes complete with a guide for proper tapping, cleaning and care.
