Filtration is removing particles

Filtration has reached equilibrium

• Leaving sample bottles open too long

• Using previously contaminated bottles

• Unaware of system operation immediately before sampling resulting in inaccurate analysis and conclusions.

• Improper handling causing contamination from hands

• Failure to flush sampling ports and lines before sampling

Surface Filtration Depth FiltrationWith surface media (paper, metals, polyester) there isno mechanism to hold dirt in place when placing the element into a dynamic system with high velocity fl owchanges and a reverse flow surging environment.

With depth media as shown above, the particles ente rthe media and work their way down into the pores an dpassages to become entrained. This provides the mechanism that holds these particles in place when used in dynamic flow surging systems.

Caking occurs on surface of media under Non-violent non-turbulent flow conditions

• Gear pump 5 - 19 GPM (18 - 72 l/min)• Viscosity up to (1000 mm 2/s)

• Integrated pressure relief valve• Filter element type = membrane filter

• high dirt holding capacity• reduced filtration costs-lowest cost per gramdirt removed

• single pass filtration rating – not required forsystem to be in “equilibrium” (constant fluid recirculation.)
