Notes ∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 40 gpm (150 L/min) for
VF609VZ3SD5 using 200 SUS (44 cSt) fluid.
RMF60
Solution:
∆P housing = 6.0 psi [.38 bar] Cartridge
∆P element = 40 x .21 x (200÷150) = 11.2 psi Elements
or
= [150 x (.21÷54.9) x (44÷32) = .79 bar]
∆P total = 6.0 + 11.2 = 17.2 psi HS60
or
= [.38 + .79 = 1.17 bar] MHS60
