Notes ∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 4 gpm (19 L/min) for
FOF601FZX1003 using 200 SUS (44 cSt) fluid.

Solution:
∆P housing = 40.0 psi [2.75 bar] Cartridge
∆P element = 5 x 4.45 x (200÷150) = 29.7 psi Elements
or
= [19 x (4.45 ÷54.9) x (44÷32) = 2.12 bar]
∆P total = 40.0 + 29.7 = 69.7 psi HS60
or
= [2.75 + 2.12 = 4.87 bar] MHS60
