Sekat Shower HD - High Diffusion

Alasan Kami Membuatnya

Kami selalu mencari cara untuk meningkatkan cita rasa dan konsistensi di setiap cangkir. HD Shower Screen dikembangkan untuk meningkatkan penyebaran air selama ekstraksi, sehingga menghasilkan pembasahan yang merata dan tekanan yang stabil.

Alat ini bekerja paling baik jika dijaga tetap bersih dan terawat.

Untuk pengalaman optimal, kami merekomendasikan penggunaannya bersama keranjang presisi kami, yang dirancang agar dapat digunakan secara optimal dengan shower screen kami.

How We Tested It

To ensure our HD (High Diffusion) Shower Screen performs across a wide range of espresso machines, we tested it on the following models:

  • Mavam Mach2 – 2 Group (Individual boiler and pump per group)
  • La Marzocco Linea PB ABR – 2 Group (1 external pump per machine)
  • Orchestrale Nota E61 (Rotary pump)
  • El Rocio Manus E61 (Vibratory pump)
  • Breville Dual Boiler / Oracle Touch (Thermoblock with vibratory pump)

These machines represent a mix of commercial, prosumer, and home-use setups.

Understanding Flow Rate & Why It Matters

Most machines are set from the factory with a 0.6mm flow restrictor, meaning that with no coffee in the basket, water should flow at around 60–80ml in 10 seconds. This is considered the industry standard for consistent extractions.

⚠️ If your machine is set to a different flow rate, our HD Shower Screen may behave differently in free flow mode.

We highly recommend checking your machine’s flow rate and pre-infusion settings before testing our screen. Flow consistency plays a key role in extraction quality.

Cara Mesin Kopi Membuang Air & Ampas

Selama siklus penyeduhan, tekanan dan residu kopi menumpuk di dalam group head. Setelah siklus berakhir, mesin melepaskan tekanan ini melalui sistem pembuangan, biasanya menggunakan katup mekanis atau elektronik 3 arah.

Berikut cara kerjanya pada berbagai jenis mesin:

  • Sebagian besar mesin E61: Menggunakan katup mekanis yang terletak tepat di bawah group head.

  • Mesin lainnya: Menggunakan solenoid elektronik 3 arah, biasanya terletak di dekat group atau di dalam sistem drainase yang menuju ke baki tetesan.

Saat Anda menghentikan ekstraksi, solenoid terbuka dan melepaskan tekanan melalui lubang pembuangan. Ini membantu mencegah penumpukan tekanan dan menyiapkan group untuk ekstraksi berikutnya.

Untuk mengurangi cipratan selama proses ini, sebagian besar mesin dilengkapi “pemecah cipratan”, yang bentuknya mirip aerator pada wastafel dapur Anda. Alat ini memperlambat aliran air yang dibuang agar lebih lancar.

Cleaning & Maintenance Tips

We've found that most machines handle residue discharge well. Solenoids (3 way valve solenoids) are built to discharge the pressure once you hit the stop button through the exhaust port. This water then travels from the group to your drain pipe or drip tray.

To avoid blockages:

  • ✅ Clean your drain valve regularly
  • ✅ Backflush your machine consistently
  • ✅ Remove the mesh in LM GS3/Linea Mini splash breakers (see guide)
  • ✅ Avoid using extremely fresh coffee (which tends to be stickier)
  • ✅ Don’t overfill your basket (e.g. using 22g in a 20g basket)

For E61 mechanical group Machine Owners

E61 groups discharge pressure mechanically after every shot. This is the most reliable and solid system and will be extremely unlikely to have any issues.

For La Marzocco machine owners

Some models, like the La Marzocco GS3 and older Linea Mini, use a fine mesh splash breaker, which can clog more easily with coffee grounds. If you want to use our shower screen on these, please consider removing the mesh or clean it often (find video on how to locate here).

For all other machines with electric solenoid:
We have found very little to no difference in the residues and we just recommend to backflush your machine regularly as per manufacturer specifications.
