Notes ∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 8 gpm (30 L/min) for
NOF501SVZX1076090D5 using 150 SUS (32 cSt) fluid.

Solution:
∆P housing = 30.0 psi [2.1 bar] Cartridge
∆P element = 8 x 0.52 x (150÷150) = 4.2 psi Elements
or
= [30 x (0.52 ÷54.9) x (32÷32) = 0.3 bar]
∆P total = 30.0 + 4.2 = 34.2 psi HS60
or
= [2.1 + 0.3 = 2.4 bar] MHS60
