Upon my inspection of the pucks in the Kwazar Foamer and the AMMO Unit (EPOCA), the felt like material in the Kwazar seems to be less dense and circularly rolled with the flow of the fluid running parallel to the flow of the filter, whereas the felt like pucks in the EPOCA are set perpendicular to flow and are of different density than the Kwazar. Now, what are the differences in the two different felt materials? Well, I haven’t been able find that answer thus far, I was trying to search if types of felts have specific colors relating to their material characteristics, but haven’t come up with any results. I did try cutting up pieces of gentler Scotch Brite pads and placing into the Kwazar unit. The addition of material helped the foaming characteristics greatly (dryer foam), but was still unable to replicate the foaming of the EPOCA unit, with the FROTHe solution being constant in both tests (transfer of product from one bottle to the other).
As far as o-rings go, the EPOCA unit uses all Viton O-rings, while I am not sure if the Kwazar unit does. The Kwazar unit does have a couple of green Viton o-rings, but I think there are one or two o-rings that I am unsure of as they are black. Physically they do not look like Viton solely based on observable color, however black Viton o-rings do exist. I am still unable to find complete product information on the Kwazar unit, where as complete product info for the EPOCA unit does exist. Back to the color of the o-rings, there is no set guideline for color coding o-rings and the colors representation of the materials characteristic, in my experience Viton o-rings have come in either green or brown, and that`s just my experience. Looking at o-rings across the entire board, their color designation is completely subjective to the manufacturers and their clients.
Pumping action, without the spots on the pumps, the Kwazar unit flows more fluid compared to the EPOCA unit. Additionally, a greater volume of fluid hits the Kwazar felt compared to the EPOCA unit, and this is simply an observation, whether the two sprayers flow different mL/sec, I am unsure. Also, the pumping action on the EPOCA *seems* more precise and *seems* like it forces more air into the container per stroke and container volume than the Kwazar pump, so it *seems* more efficient.
