Technical Notes
For element sizes not listed, contact Synder Filtration for details. Elements can be designed to fit specific needs by specifying the element outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length. Elements are also available with or without a controlled bypass tail. Additional feed spacers are also available. Trials should be conducted to determine optimal application conditions.
