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 24 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.
