STJH-MINI-PLEAT-ULPA-U17-35

Mini-Pleat ULPA Filter 35 mm U17

The highest-efficiency 35 mm ePTFE pack for process tools that require U17 performance and can support its resistance.

U17 highest series grade
0.55 in. w.g. at 100 fpm
Boron-free membrane pack

Введение продукции

This U17 model is the most selective member of the 35 mm ePTFE mini-pleat series, reaching at least 99.999995% efficiency at MPPS. Its nominal clean resistance is 0.55 in. w.g. at 100 fpm, so it should be reserved for contamination-sensitive tools whose risk assessment warrants the airflow penalty. Supported membrane layers and an anodized aluminum perimeter provide a compact filter platform for several seal systems.

Основные характеристики

Minimum penetration tier

U17 acceptance provides the tightest MPPS efficiency in this family for the most sensitive manufacturing steps.

Clearly defined pressure cost

The 0.55 in. w.g. clean value makes the airflow consequence visible before U17 is applied across a ceiling or tool.

Compact protected medium

Scrim-supported ePTFE folds fit a 35 mm pack while resisting damage at the pleat bends during normal handling.

Applications

Reserved for leading-edge semiconductor tools, metrology spaces and mini-environments that explicitly require U17 filtration. System designers should avoid applying it by default where U15 or U16 meets the control target with lower energy use.

Solutions for Your Application

U17 is specified throughout the room even though only a few process tools need it.Map the most sensitive zones and use the U17 panel locally where its 0.55 in. w.g. clean resistance is justified.

The higher-resistance replacement reduces delivered face velocity below the process setpoint.Commission fan output after installation and compare actual flow with the 100 fpm design basis instead of relying on the previous filter setting.
