Description
xCAPFEI's 51mm bottomless portafilter with three ears is a stainless-steel replacement designed to fit CASABREWS CM5418, 3700 Series and other 51mm three-ear home espresso machines, complete with a 2-cup double-shot filter basket.
If you want clearer feedback during extraction and a durable, easy-to-clean portafilter for your home espresso setup, this CAPFEI 51mm bottomless unit gives visual control over the shot and includes a 2-cup stainless steel filter basket sized for double shots (holds up to about 16 g). Built from food-grade 304 stainless steel with a removable design, it’s made to resist rust and be simple to maintain while fitting multiple popular machine brands.
Which machines will this portafilter work with?
It’s engineered for 51mm three-ear group heads where each ear measures roughly 3.88–4.00 mm thick. Compatible models listed include CASABREWS CM5418 and the 3700 Series, Mr. Coffee Espresso and Cappuccino machines, plus many alternative home brands.
- Fits CASABREWS CM5418 and 3700 Series
- Compatible with Mr. Coffee Espresso & Cappuccino machines
- Also suits machines from Yabano, Hamilton Beach, Swan, Homever, Chefman
- Requires three-ear group head with ear thickness ~3.88–4 mm
How does the bottomless design improve extraction awareness?
A bottomless portafilter exposes the underside of the puck so you can immediately see channeling, uneven flow, or dose inconsistencies. That visual feedback helps you diagnose tamping, grind size, or distribution issues faster than a standard spouted portafilter.
- Reveals flow rate, color changes, and striping during extraction
- Helps identify channeling and puck defects in real time
- Useful for dialing in grind, dose, and tamp pressure
What are the construction and hygiene advantages?
Made from 304 food-grade stainless steel, this portafilter resists oxidation and corrosion for long-term use. The removable design simplifies cleaning—no hidden corners—so regular rinsing and deep cleans keep the portafilter sanitary and odor-free.
- 304 stainless steel resists rust and corrosion
- Detachable components for easy rinsing and soak cleaning
- Durable surface withstands daily home use
What does the included filter basket offer?
The package includes a 51mm stainless steel double-shot (2-cup) filter basket sized to hold up to approximately 16 grams of coffee, appropriate for many double-shot home extractions. The basket installs like a standard portafilter insert so you can switch between baskets or back to a spouted unit if desired.
- 51mm diameter, 2-cup capacity filter basket
- Holds roughly up to 16 g—suitable for many home double shots
- High-grade stainless construction matches the portafilter body
Who is this for? Home baristas and hobbyists who want clearer visual feedback during extraction, a robust stainless-steel replacement part for their 51mm three-ear machine, or a simple upgrade to diagnose and improve shot consistency will benefit most. It’s ideal if you own one of the compatible machines (CASABREWS, Mr. Coffee, Hamilton Beach, etc.), prefer corrosion-resistant materials, and want components that are easy to remove and clean. If you need reassurance about fit, contact CAPFEI with your machine model to confirm ear thickness and compatibility before ordering.
