Element selections are predicated on the use of 150 SUS (32 cSt)
petroleum based fluid and a 40 psi (2.8 bar) bypass valve.
Shown above are the elements most commonly used in this housing.
Note: Contact factory regarding use of E Media in High Water Content, Invert Emulsion and Water Glycol
Applications. For more information, refer to Fluid Compatibility: Fire Resistant Fluids, pages 19 and 20.
Sizing of elements should be based on element flow information provided in the Element Selection chart above.

Exercise:
Determine

Solution:
P

= 7.0 psi [.50 bar]
P

or
P
