ePTFE Membrane Media

Proven Alternative to Glass Fiber Media

In the early 1990s, Daikin Industries discovered an ultrafine fiber structure that revolutionized ULPA filters for the microelectronics industry. Using this unique structure, AAF developed MEGAcel® ULPA filters with ePTFE membrane media that provide:

  • Lowest off-gassing properties
  • Lowest pressure drop
  • Far superior tensile strength and durability

Lowest Off-gassing Properties

The manufacturing of microelectronics requires purity of air and product for the proper doping of semiconductors.

  • Traditional glass media represents a potential source of boron contamination, which can damage the electrical properties of integrated circuits.
  • Additionally, phosphorus may occur in flame retardants of certain polyurethane sealants used to seal the media pack to the filter frame.

MEGAcel II ePTFE ULPA filters are built free from boron and phosphorus, and they are factory-tested for your reassurance.

Lowest Pressure Drop = Lower Energy Use

Because of its significantly lower pressure drop, ePTFE media delivers energy savings of up to 60% as compared to traditional glass media.

ePTFE vs Glass ULPA FiltersFar Superior Tensile Strength and Durability

In contrast to glass media, ePTFE media proves nearly indestructible. Operators of microelectronics applications have found that they no longer need to maintain an extra supply of ULPA filters due to damage stemming from routine handling, installation, and testing.
