Produkteinführung

This full-module panel pairs the highest U17 efficiency in the series with a reverse gel interface and 35 mm boron-free ePTFE pack. It is meant for critical process zones where the reduction in particle penetration outweighs higher system resistance. Because the external face remains similar to lower grades, purchasing records should state U17 acceptance, gel orientation and test airflow unambiguously.

Key Features

Critical-zone particle barrier

U17 efficiency targets the most sensitive semiconductor operations rather than general cleanroom coverage.

Continuous fluid interface

The reverse gel trough surrounds the full face and supports repeatable blade engagement in a compatible grid.

Robust membrane support

Spunbond layers on both sides of the ePTFE membrane help protect the high-grade pack from handling stress.

Applications

Applied locally in leading-edge semiconductor process bays, tool mini-environments and critical metrology spaces where U17 is explicitly required. It should be integrated with sufficient fan reserve and a grid designed for the reverse gel configuration.

Solutions for Your Application

U17 panels are mixed with lower grades because the frames look alike.Use unique receiving inspection records tied to model code, efficiency label, seal side and ceiling location before unpacking.

The ceiling fan cannot recover design flow after the U17 changeout.Budget for the 0.55 in. w.g. clean resistance at 100 fpm and reserve U17 coverage for zones that truly need it.

Specify finished dimensions, overall frame series, gel location, faceguard material, divider or test ports and required airflow test point.
