STJH-EPTFE-ULPA-U17

ePTFE Membrane ULPA Filter U17

The highest-efficiency supported ePTFE option for critical tools where U17 protection outweighs added fan resistance.

U17 MPPS acceptance
Boron-free ePTFE media
Gasket, gel or blade frames

Introduction de produit

This U17 ePTFE model is specified for the narrow set of process tools and mini-environments that require the series' lowest particle penetration. It retains boron-free supported membrane construction but carries the higher nominal resistance of 0.55 in. w.g. at 100 fpm. The broad seal menu is useful for retrofits, provided the selected aluminum frame matches the tool's actual mating surface.

Key Features

Highest membrane efficiency

U17 acceptance addresses exceptionally sensitive tool environments that cannot use the lower U15 or U16 tier.

Seal-system adaptability

The media pack can be paired with dry compression, fluid gel or knife-edge interfaces for varied OEM equipment.

Defined airflow tradeoff

The 0.55 in. w.g. reference reveals the fan-pressure consequence before the highest grade is adopted.

Applications

Intended for the most contamination-sensitive semiconductor process tools, critical mini-environments and advanced metrology zones. It should be deployed selectively, with fan capacity, filter-test flow and the OEM seal interface confirmed before purchase.

Solutions for Your Application

The highest efficiency is chosen as a default even though it erodes tool airflow margin.Reserve U17 for documented critical points and compare its 0.55 in. w.g. clean drop with the tool fan curve.

An OEM tool uses a nonstandard face dimension or divider arrangement.Provide the approved interface drawing, net face area and divider or test-port layout instead of ordering a nominal panel size.

Options disponibles

State special face size, frame depth, seal type and side, faceguard alloy, divider orientation and test-port count.
