UH319 Filter Moisture & Particulate Combo Filter: For Critical Fluid Condition Monitoring

 

 

Pressure Drop Information

Housing pressure drop using fluid with 0.9 S.G.
Housing pressure drop is directly proportional to specific gravity.

 

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. Note: factors are per 1000 L/min and per 1 US gpm.

Sample ΔP calculation

UH319 Series 13 in. length housing with S24 (1¹⁄₂ in.) side manifold mount ports using AN grade media. Operating conditions 300 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
= (0.30 x 1.2/0.9) bard (housing)
+ ((300 x 1.09/1000) x 50/32 x 1.2/0.9) bard (element)
= 0.40 (housing) + 0.68 bard (element)
= 1.08 bard (15.7 psid)
