Microza1 Ultrafiltration Modules OAT Series for Enhanced Efficiency and Cleanliness

The Microza1 OAT ultrafiltration (UF) modules feature the latest high flow hollow fiber technology using a newly developed asymmetric support structure and a dual skin cut off layer on both the inside and outside of the fiber.

  • Dual rated at 2 nm by Pall’s gold nanoparticle challenge test and 4 kD molecular weight cut off
  • Diffusion driven contamination control avoids accumulation on membrane
  • 20 nm particle rinse up control
  • Low metal extractables by pre elution using new hot water rinsing process
  • Up to 12 months on shelf life ex works due to hot water sanitization2
  • Shipped water wet
  • 100% integrity tested and documented
  • High temperature and pressure modules available

Application

The Microza OAT modules are used in today´s most demanding ultra high purity water systems. The outer module dimensions and connections are compatible with Microza OLT 6036 series. Therefore they are also suitable for upgrades of existing installations.
