Pressure Drop Information

Housing pressure drop using fluid with 0.9 S.G.

Element Pressure Drop

Multiply actual flow rate times factor in table below to determine pressure drop with fluid at 32 cSt (150 SUS), 0.9 S.G. Correct for other fluids by multiplying new viscosity in cSt/32 (SUS/150) x new S.G./0.9.

Section 1 Housing P/N:

Note: Pall Athalon filter housings are supplied without filter elements or warning devices fitted. Never operate the filter unless a filter element is fitted and all warning device ports are sealed.

Housing part number designates indicator port is fitted with a plastic shipping plug.

Section 2 Spin-On Can P/N: HC7400 S[Table 1] [Table 2] H

Section 3

Differential Pressure Indicator P/N: RC [Table 1] Z [Table 2] Z

Note: If no differential pressure indicator is selected, ‘B’ type blanking plug (P/N HC9000A104Z) must be ordered separately and fitted to replace the plastic shipping plug.

Note: Z indicates fluorocarbon seals are standard. Other options are available; contact Pall.
