For those still looking for cheap alternatives, Home Depot now carries a HUSKY water separator that's twice as big as the one from the OP (the reservoir volume is appr. 2" diam x 4" tall). Same installation but you need two 3/8" to 1/4" adapters for the threads in the input and output, as they are larger. This thing will give you the pressure drop you need for this to be effective. It has the metal filter and turbulence element that can be removed, just as before. Looks sharp, too. - $22
The two 3/8" to 1/4" adapters you need as well...
