I have been slowly tweaking my home shop, to make it a more useful and functional environment. For Christmas, I got a small air compressor, and I have found it to be an incredibly handy item. However, almost all the attachments to fill tires are for the Schrader valve (American valve), while I deal with only the Presta (Sclaverand or French valve). I have used the cheap adapters that you can find at any LBS, but they don't seal that well and are a pain to use. I finally located a set up that was made specifically for Presta named the Prestaflator, and it even included a nice pressure gauge. The unit is made by Prestacycle based out of Waterford, New York.
The Prestaflator uses a trigger to release air for inflating tires or as a blower through its attachable hose, which has an adapter head for Presta or Schrader valves.
