The recommended cross flow rate will be subject to differential pressure limitations
and specific applications. Please consult Synder Filtration if additional information is
needed.
For element sizes not listed, please call or email Synder Filtration for details. We can design
an element to fit your exact needs – just specify 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.
