Stainless Steel Blind Filter 58mm
The blind filter is used for backflushing and cleaning your semi automatic espresso machine grouphead, screen and the relief valve.
It fits standard size 58 mm commercial portafilter handle.
When performing back flush cleaning, remove the regular (single or double) filter out of your prtafilter handle and insert the blind filter instead. Use about 1/2 packet Urnex cafiza powder and follow back flush instructions.
*Not for use with basic home coffee machines that do not have a 3 way relief valve. |
