Produkteinführung

This U17 supported membrane provides the lowest penetration of the three ePTFE grades and carries the highest nominal resistance basis: 0.55 in. w.g. at 100 fpm for a 35 mm pack. Spunbond support protects the boron-free membrane through mini-pleating, while low-offgassing material selection suits critical semiconductor tools. U17 should be specified only where the process needs its efficiency, because extra media area or fan pressure is normally required relative to U15 and U16.

Key Features

Lowest family penetration

The U17 membrane grade addresses the most stringent particle-control applications in this series.

Composite handling strength

Spunbond backing on both sides reduces direct mechanical stress on the functional membrane.

Critical tool cleanliness

Boron-free, low-emission construction supports contamination-sensitive semiconductor mini-environments.

Applications

For critical semiconductor process tools, mini-environments and ultra-clean supply terminals where U17 performance is justified by contamination risk.

Solutions for Your Application

The high-efficiency sheet exceeds FFU pressure capability at the planned airflow.Increase pack media area, evaluate lower face velocity and verify the 0.55 in. w.g. reference against the complete fan curve.

A small conversion defect compromises a U17 element despite undamaged sheet elsewhere.Use controlled pleating and sealing, then scan every finished filter under the selected classification method.

Verfügbare Optionen

Specify U17 roll width, support structure, pack depth, pleat pitch, spacer chemistry, frame, gel system, airflow and scan protocol.
