Looks like a VERY expensive (circa $250) kit that adds an integrated low pressure air compressor to your water system. Pass.
Iíll stick with an oil less shop air compressor set to about 20-30 psi and a quick connect fitting for the city water inlet. The compressor I already have, and a brass quick connect is only a few bucks. Quick, cheap, and only requires running an air hose to the side of the Airstream utility connection area.
