In-Tank Water Softener Filter 37 × 81 mm – OCS Nical Type

In-tank softener filter for tank-fed espresso machines

This 37 × 81 mm softener cartridge connects to the intake hose inside your espresso machine’s water tank. Water is drawn through ion-exchange resin before it reaches the pump, so less hardness ends up as scale in the boiler and group.

Capacity and use

It uses a strong cation-exchange resin. Rated output is about 22 L at 18 °fH, 16 L at 27 °fH and 9 L at 45 °fH, so harder water means more frequent changes. Use with water between 0 and 40 °C.
