Professional Blind Filter Basket for Espresso Machine Backflushing
The Ø53 mm Blind Filter Basket is designed for performing the Backflush cleaning procedure on commercial and semi-professional espresso machines equipped with a three-way solenoid valve.
By sealing the water outlet inside the portafilter, the cleaning solution is forced back through the brewing group under pressure, effectively removing coffee oils and brewing residues from the internal components of the espresso machine.
Why Is Backflushing Important?
During daily espresso preparation, coffee oils and fine coffee particles gradually accumulate inside the brew group, three-way valve and internal brewing circuit. Without regular cleaning, these residues can negatively affect espresso flavour, brewing consistency and machine reliability.
Routine backflushing helps maintain stable extraction performance while extending the service life of internal components.
How to Use
Insert the Blind Filter Basket into the portafilter, add the recommended amount of Puly Caff, lock the portafilter into the group head and perform the backflush cycles according to your espresso machine manufacturer's instructions.
After cleaning, complete several rinse cycles using clean water to remove any remaining detergent.
Complete Brew Group Maintenance
Backflushing cleans the internal brewing circuit, but complete maintenance should also include manual cleaning of the group gasket and espresso shower screen using a BARISTA Group Cleaning Brush.
Together with Puly Caff, this maintenance routine helps remove coffee residues from every critical area of the brew group, ensuring consistent espresso quality and reliable machine operation.
Compatibility
Compatible with espresso machines and portafilters using Ø53 mm filter baskets.
Please verify your filter basket diameter before ordering.
