描述
Varafine filters are well suited for ultra high purity DI water applications where very fine removal ratings and extremely high flow rates are required for economical installations. These filters contain a highly asymmetric polysulfone membrane that results in exceptionally low pressure drop values.
- Available in removal ratings from 0.02 μm to 0.45 μm
- Double layer, patented highly asymmetric polysulfone membrane
- Rapid rinse-up
- Integrity testable
- Manufactured in cleanroom environment
