E&B Lab Puck Diffuser Screen (by IMS)
Elevate your espresso extraction consistency with the E&B Lab Puck Diffuser Screen. Developed in Italy by IMS Filtri, this premium, reusable tool replaces thick, high-maintenance mesh screens with an ultra-thin, photo-etched membrane. Designed to deliver flawless water distribution across the coffee bed, it eliminates channeling while keeping your espresso machine’s group head perfectly clean. It is the ultimate workflow accessory for home baristas and specialty cafes looking to perfect their extraction mechanics.
Key Product Features & Benefits
- Advanced IMS Filtration Technology: Combines a precision outer plate with an integrated, photo-etched interior membrane. This dual-layer architecture helps guarantee optimal water saturation across the entire surface of your coffee puck.
- 150-Micron Photo-Etched Membrane: Features an ultra-fine AISI 301 stainless steel membrane. The 150-micron filtering power helps stabilize delivery pressure, smooth out water flow, and protect flavor clarity.
- Precision Diffuser Hole Pattern: Built with 257 strategically placed holes, each measuring 2.4 mm in diameter. This configuration helps eliminate hard jets of water from the shower screen to reduce localized channeling.
- Flawless Group Head Cleanliness: Acts as a protective barrier between the coffee bed and your machine’s group head. It helps prevent coffee oils, grounds, and fines from being sucked back into the three-way solenoid valve.
- Magnetic Removal Pin Included: Packaged with a convenient magnetic tool to safely lift the hot metal screen directly out of your portafilter basket immediately after brewing.
- Seamless Multi-Beverage Synergy: Engineered to complement the E&B Lab All-in-One filter basket. This combination helps ensure unmatched flow control during traditional espresso extractions, filter-style coffee brews, or delicate tea infusions.
- Effortless Chemical-Free Cleaning: Designed with a smooth, solid membrane surface that helps prevent coffee residues from getting trapped inside. Simply rinse under warm water and wipe down with a non-abrasive cloth—no harsh cleaning powders required.
