Filter SELECTION Example: TOTAL DIFFERENTIAL PRESSURE ACROSS COMPLETE Filter . Element: 0140 D 010 BH3HC. The total differential pressure of the clean Filter is the sum of housing and element differential pressure at operating viscosity. Required: pelement at ptotal = phousing at Q + f x pelement at Q operating viscosity = 46 mm /s for ptotal = total differential pressure across Filter Q = 15 l/min phousing at Q = housing differential pressure 46. Solution: pelement for 46 mm /s = x (determined with the aid of housing graphs - 30. see relevant Filter brochure).
