Our Double-Spring Leveling coffee tamper contains the following flange and springs:
Two stainless steel flanges (bases):
A leveler flange – this flange sits on the top of a filter basket, and acts as a ‘leveler’ ensuring that a barista tamps straight down and not on an angle;
A compression flange – this flange compresses/makes contact with the ground coffee in the filter basket and can be ordered to fit your specific filter basket size.
Spring 1 – Spring 1 is a pre-calibrated spring that sits inside of the Eazytamp assembly. It is used to compress the compression flange using either 10 kilos (red spring) or 15 kilos (silver spring) of pressure. This spring ensures consistent pressure is used when the barista tamps ground coffee. Both springs are provided with the tamper and are interchangeable.
Spring 2 - This is a large spring that ensures that the star flange returns to its original leveling position after tamping occurs. This spring has no bearing on the pressure exerted on ground coffee.
