Dimensional Drawings

Dimensions in mm (inches)

The equipment has been assessed in accordance with the guidelines laid down in The European Pressure Directive 97/23/EC and has been classified within Sound Engineering Practice S.E.P. Suitable for use with Group 1 and 2 fluids only. Consult Sales for other fluid gas group suitability.

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

UR699 Series 40” length housing with F40 ( 2.5” ISO 6162) split flange ports using AN grade media. Operating conditions 500 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
= (0.28 x 1.2/0.9) bard (housing)
+ ((500 x 0.23/1000) x 50/32 x 1.2/0.9) bard (element)
= 0.37 (housing) + 0.24 bard (element)
= 0.61 bard (8.8 psid)

Housings, Vessels, or Assemblies

For new installations, select one complete part number from each section below

Section 1 Housing P/N: UR 669 C [Table A] [Table 4] 9

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.
