The 54/51mm bottomless portafilter has been designed as a replacement for the original portafilters of compatible commercial espresso machines. The only use of the product is to prepare coffee from ground coffee. Bottomless portafilters are designed differently than regular portafilters to allow the user to observe the coffee extraction live. Please note that the portafilter reaches high pressures during use, so handle it with care and keep it away from children.
