Domegaia makes and sells the Little Dragon foam machine. It uses an expensive, high-pressure, self-priming, Aquatec pump, a pressure regulator and a solenoid valve, with a dial indicator. It fits conveniently on top of a standard 5-gallon bucket and is very simple to operate. The Little Dragon foam machine is attached to an air compressor.
By eliminating the expensive pump and a few other parts, it is possible to reduce the cost of the foam machine.
The Sustainable Center of Oregon has designed, built and sells an AirCrete Foam Machine for 70% less than the Little Dragon.
The DIY Sustainable AirCrete Form Machine splits the air from the air compressor
