Eureka Mignon Single Dose 45g Hopper Blow Up Bellows

The Eureka Blow Up Bellows is the genuine Eureka silicone rubber lid that converts the 45g clear single-dose hopper into a true zero-retention setup. If you weigh every dose and want the same weight of ground coffee back out, this is the part that makes it happen.

Why it matters

Even a well-designed grinder holds a little coffee in the burr chamber and exit chute between doses. That retained coffee is stale by the time it reaches your next shot, and it throws your dose weight off. The Blow Up system solves it mechanically: press the bellows lid and a pulse of air pushes the leftover grounds through the chute and into your portafilter. 18 grams of beans in, 18 grams of ground coffee out.

Features

• Genuine Eureka part: Original factory silicone rubber bellows (Eureka code 2316.0070AR00-1Kit), not an aftermarket copy — correct fit and correct material.
• Zero-retention single dosing: Paired with the 45g clear PVC single-dose hopper, it flushes the grind path after every dose so your output weight matches your input.
• Fresher in the cup: Clearing stale grounds between doses means each shot is pulled entirely from coffee you just ground — important if you switch beans often or rotate through single origins.
• Food-safe silicone: Flexible, durable and easy to wipe clean; it seals the hopper between uses to keep beans protected.
• Simple to fit: Drops straight onto the small clear hopper used across the newer Eureka Mignon range — no tools, no modification.

Compatibility

This bellows fits the 45g hopper only. Used together, the bellows and 45g hopper fit:

• Confirmed: Mignon Zero, Brew Pro, Classico, Chrono, Design, Filtro and Filtro Silent, Facile (Easy), Manuale, Perfetto, Specialita, Silenzio, Mignon XL, Mignon Dolce Vita, Mignon Stark.
• Should fit, not confirmed: original Eureka Mignon, Mignon MKII, Nuova Simonelli MCF. Older Mignon hopper openings measure roughly 41mm × 14mm — about 3mm shallower and marginally narrower, so expect a slightly tight, slightly tall fit.
• Does not fit: Eureka Atom.

The current 45g and 510g hoppers share the same 41.7mm × 17mm opening as the taller 510g hopper found on the Specialita range.

What's included

• Rubber bellows lid only

Please note: the 45g single-dose hopper itself is sold separately. This listing is for the bellows lid.
