TECHNICAL NOTES

For element sires not listed, please coil or email Synder Filtration for Moils. We can design on element to fit your exact needs -just specify the element outer diameter (OD) or vessel/housing inner diameter OD), element inner diameter OD, and length. Elements ore also available with or without a controlled bypass tall Additional feed spacers are also available. Trials should be conducted to determine optimal application.
