ANTI-STATIC FILTER ELEMENTSHILCO® PH-CGJ SERIES Static discharge is a common problem in the lubricating oil systems of today's turbo-machinery. Type II lubricant base stocks exhibit very low fluid conductivity. As a result, static charges can build on the non-conductive components of the lube oil system, such as the filter elements. When a sufficient charge is accumulated, static discharge occurs between two points of differing potentials. Over time static discharge contributes to oil degradation and varnish build up throughout the system. HILCO® PH-CGJ style filter elements incorporate conductive fibers which are copleated in between two layers of hi performance microglass filter media. As a result the Hilco® antistatic filter element dissipates static charge build up before discharge can occur.The HILCO® CGJ style elements are available in every standard HILCO® media grade code. Originally developed in the mid 1990s to solve a static discharge problem for a power plant in Japan, customers have successfully relied on HILCO® antistatic filter elements for years. The HILCO® PH-CGJ elements are a direct replacement for all HILCO® standard size filter elements. Users which have converted from standard HILCO® PH series elements to the anti-static version report only a modest increase in pressure drop. Differential characteristics of a PH739-05-CGJ element is illustrated on back.

Differential Pressure (psid) Pressure vs. Flow Rate PH739-05-CGJ Element Only Fluid conductivity can be determined by utilizing ASTM standard D2624. A common unit of conductivity is a Peco Siemens/Meter (pS/M). Laboratory and field testing reveals that fluid conductivity greatly effects the number and severity of static discharge. Oils having a conductivity < 35 pS/M are prone to hi intensity static discharges while oils > 200 Ps/M exhibit no static problems. HILCO® offers full laboratory services and can verify the conductivity of a user's oil if a static discharge problem is suspected.
