Single dosing on the Quamar T48E

The T48E is built for volume: 83 mm flat steel burrs, a 480 W motor, three electronic dose settings, a reset-proof counter and micro-adjustment of grind size. Quamar rate it for up to around 8 kg of ground coffee a day, and offer bean hoppers in four different capacities.

That range of hopper options is a clue to how it is meant to be used — you pick a capacity that matches your throughput and keep it fed.

When throughput is not the goal

Used at home, in a roastery, or for dialling in, none of those four hopper sizes is the right one, because the right size is a single dose. This hopper replaces whichever you have with one that holds exactly the beans you weighed.

Grind, then press the silicone bellows to clear the chamber and chute. On an 83 mm burr set that internal volume is significant, and it is the reason consecutive doses of different coffees blur together without a purge between them.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

How it is made

• 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
• Factory machine moulded: silicone bellows

Materials

• Lid, lock ring, connector: PETG hard plastic
• Air-leak prevention gasket: TPU — material info
• Bellows: factory moulded silicone

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
