ePTFE Membrane ULPA Filter Media U15 Supported

A supported boron-free U15 membrane offering the lowest nominal resistance tier in this ePTFE group.

U15 supported ePTFE
0.33 in. w.g. nominal basis
Boron-free construction

Perkenalan produk

A single ePTFE membrane layer is protected on both sides by spunbond support, improving handling strength during mini-pleating and service. The U15 version is the lowest-resistance grade in the series, with a nominal complete-filter basis of 0.33 in. w.g. at 100 fpm for a 35 mm pack. Boron-free construction and low offgassing suit semiconductor applications, while complete-filter classification remains necessary after conversion.

Fitur utama:

Two-sided membrane support

Spunbond layers shield the thin ePTFE membrane from handling and pleating damage.

Lowest family resistance

The U15 grade provides the lightest documented pressure burden among the three supported membrane options.

Microelectronics material profile

Boron-free, low-offgassing construction addresses sensitive semiconductor air requirements.

Applications

For low-energy semiconductor ULPA filters, fan filter units and robust cleanroom panels that require U15 efficiency with a supported membrane.

Solutions for Your Application

An unsupported membrane tears during pleating or installation.Use the two spunbond support layers and maintain converter settings suitable for the composite structure.

The nominal 0.33 in. w.g. value is applied to a different pack depth or face velocity.Recalculate and test pressure drop for the actual pleat area, 35 mm reference pack and operating airflow.

Pilihan yang tersedia

Specify roll width, membrane grade, support basis, pleat depth and pitch, separator adhesive, frame, gel or gasket and test class.
