IMS Competition E61 Shower Screen 200 IM — 60 mm | Integrated Membrane 200 µm
💧🎯 Better Water Distribution. More Uniform Extraction. Precision Behind the Puck.
The IMS Competition E61 200 IM Shower Screen is a precision-engineered upgrade for compatible E61 espresso machines, featuring an integrated stainless steel membrane with a 200 µm (0.20 mm) filtering specification.
While baristas often focus on grinders, precision baskets and puck preparation, the way brewing water reaches the coffee bed deserves just as much attention. This IMS Competition shower screen is designed to distribute water more evenly across the puck, particularly during pre-infusion and the initial stages of extraction.
An excellent upgrade for serious home baristas and coffee professionals in Weesp, Amsterdam and beyond who want greater control over their espresso.
💦 Why Your Shower Screen Matters
Before water can extract the flavours from your coffee, it must first travel through the espresso machine's group head and shower screen.
The shower screen influences how water is distributed over the coffee puck. Uneven water delivery can contribute to localised wetting, erosion or inconsistent saturation, especially during the first seconds of brewing.
The IMS Competition screen addresses this with a carefully engineered combination of a perforated support disc and an integrated fine membrane.
- 💧 200 µm integrated membrane — provides fine water distribution across the shower surface.
- 🎯 98 circularly distributed perforations — the external support disc features 98 holes, each 3 mm in diameter.
- ⚙️ Integrated construction — the membrane is formed directly within the shower disc assembly and secured by caulking.
- ☕ Improved initial wetting — designed to promote more uniform water delivery during pre-infusion.
- 🔧 E61-compatible design — a precision replacement for many machines using the standard E61-style shower screen.
- ♻️ Durable construction — a serviceable replacement part that helps maintain consistent group-head performance.
🔬 What Does 200 µm Actually Mean?
The membrane's specified filtering capacity is 200 micrometres, equivalent to 0.20 mm.
For perspective, a typical human hair is approximately 50–100 µm thick, although its diameter varies considerably.
That means the membrane's 200 µm specification is roughly two to four times the diameter of a human hair.
This fine membrane helps distribute brewing water through many small openings rather than allowing it to emerge directly through the larger support-disc perforations.
The result is a more finely distributed flow of water towards the coffee bed.
👃 CoffeeNose Insight — Water Distribution Is Part of Extraction
We spend a lot of time discussing precision baskets, WDT tools, tampers and puck screens. But what happens above the coffee puck is equally worth understanding.
The way water “rains” onto your coffee from the shower screen influences how the puck becomes saturated and how extraction develops.
During espresso extraction, several factors work together:
- 💧 Water distribution — how evenly brewing water reaches the puck.
- 🌡️ Temperature — influences extraction kinetics and the solubility of flavour compounds.
- 🧪 Water mineral composition — affects extraction chemistry and sensory perception.
- ⚙️ Flow rate — determines how quickly water moves through the system and coffee bed.
- 📈 Pressure — influences flow through the resistance created by the puck.
- 🌀 Puck preparation — determines the distribution, density and permeability of the coffee bed.
A good shower screen is particularly interesting during pre-infusion, when the dry coffee bed first becomes saturated.
However, it would be misleading to claim that the shower screen has exactly the same impact as water chemistry, temperature or puck preparation in every extraction. Its influence depends on the machine, pressure and flow profile, basket, dose and coffee preparation.
Our recommendation: Start with a clean, well-functioning group head, a suitable precision basket and consistent puck preparation. Then consider an IMS Competition shower screen to refine water delivery.
A premium shower screen cannot compensate for poor puck preparation, but it can remove one potential source of uneven wetting.
🛠️ Integrated Membrane — Engineered as One Assembly
Unlike a construction where the membrane is simply placed loosely against the support disc, the IMS integrated-membrane design incorporates the filtering layer into the shower assembly.
The membrane is fixed to the shower body by caulking, creating a unified structure.
This construction is intended to maintain the relationship between the perforated support disc and the fine filtering membrane during use.
The external support disc features 98 circularly distributed holes of 3 mm diameter, while the membrane provides the finer 200 µm distribution layer.

Important compatibility note: Not every machine from these brands uses the same shower screen. Even within a model family, group-head revisions can differ. Verify the existing screen's dimensions, retaining mechanism and group-head geometry before ordering. The compatibility list should be treated as manufacturer-supplied guidance rather than a universal fit guarantee.
🧽 Installation & Maintenance
A precision shower screen performs best when kept clean.
- 🔧 Remove the existing shower screen according to your machine manufacturer's instructions, with the machine switched off and cooled.
- 🧽 Clean the group-head recess and inspect the retaining gasket or mounting components.
- 💧 Install the IMS screen correctly without bending or damaging the integrated membrane.
- ☕ Flush the group head and check for correct seating and normal water delivery.
- 🧴 Maintain the screen with regular cleaning and appropriate espresso-machine cleaning products.
CoffeeNose maintenance tip: Coffee oils, fine particles and mineral deposits can progressively obstruct a shower screen. A clean standard screen may outperform a neglected precision screen. Regular backflushing and periodic inspection remain essential.
💚 Why We Like It at WB.coffee
👃 The CoffeeNose recommends the IMS Competition screen as a thoughtful upgrade for a well-maintained E61 espresso machine.
We often pay close attention to what happens inside the basket, while overlooking how water first reaches the coffee. The fine integrated membrane and engineered support disc make this a worthwhile component to consider when refining pre-infusion and extraction consistency.
It's not a miracle upgrade, but it addresses a real part of the brewing process — and that's exactly the kind of engineering we appreciate.
