Espresso Puck Screen is used for spreading shower-head water evenly over the espresso puck and keeping the group-head screen clean. FDA 21 CFR is the reference cited for it on drawings, datasheets and purchase orders.
What FDA 21 CFR Means for Espresso Puck Screen
The dimensions in the table below are supplied to suit FDA 21 CFR. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Espresso Puck Screen Dimensions
| Size | Diameter (mm) | Thickness (mm) | Construction | Micron rating (u00b5m) |

| 53 | 53.3 | 1.7 | Sintered 4-layer + 1 mm perforated | 150 |

Specifying Espresso Puck Screen Beyond the Standard
- Diameter: Choose 0.2–0.5 mm under the basket inner diameter so the screen sits flat without binding.
- Thickness: A 1.7 mm sintered screen raises headspace use; a 1.0 mm single-mesh screen suits shallow baskets.
- Construction: Sintered multi-layer screens are rigid and stay flat; laser-cut single mesh is lighter and cheaper.
When Espresso Puck Screen Is Not the Right Choice
Not useful in pressurized baskets or capsule machines, where water distribution is set by the machine.
