Performance
Pressure Drop Information
Housing pressure drop using fluid with 0.9 S.G.Housing pressure drop is directly proportional to specific gravity.
- Keeps fluids the cleanest, longest, for the greatest value
- Provides consistent, reliable, protection of system components over the full service life of the filter element
- Rapidly achieves and sustains required fluid system cleanliness
- Delivers maximum filter capacity in the smallest footprint
- Prevents electrostatic discharge from damaging your filter and degrading your fluid
Element Pressure Drop
610 Series Filter Elements – bard/1000 L/min (psid/US gpm)
| Length Code | AZ | AP | AN | AS | AT |
| 20 | 1.31 (0.072) | 0.56 (0.030) | 0.43 (0.023) | 0.31 (0.017) | 0.19 (0.011) |
| 40 | 0.70 (0.038) | 0.30 (0.016) | 0.23 (0.013) | 0.17 (0.009) | 0.10 (0.006) |
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. Note: factors are per 1000 L/min and per 1 US gpm
Sample ΔP calculation
UR629 Series 40” length housing with F48 (3” SAE) split flange ports using AN grade media. Operating conditions 600 L/min flow rate using a hydraulic fluid of 50 cSt and specific gravity (s.g.) 1.2.
Total Filter ΔP= ΔP housing + ΔP element
= (0.45 x 1.2/0.9) bard (housing)
+ ((600 x 0.23/1000) x 50/32 x 1.2/0.9) bard (element)
= 0.60 (housing) + 0.29 bard (element)
= 0.89 bard (12.9 psid)
Ordering Information
For new installations, select one complete part number from each section below
Section 1: Housing P/N: UR [Table A] [Table B] [Table C]
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.Note:Z indicates fluorocarbon seals are standard. Other options are available;contact Pall. Housing P/N designates indicator port fitted with a plastic shipping plug.

Section 3 (At least one Differential Pressure Indicator or ‘B’ type blanking plug must be ordered for each filter tower)
Differential Pressure Indicator P/N: RC [Table 7] Z [Table 8] ZNote: 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 in each filter tower.
For typical installations, only 2 indicators are required – only one housing per side requires an indicator. Replace other shipping plugs with blanking plugs.
Note :Z indicates fluorocarbon seals are standard. Other options are available; contact Pall.
