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 co-pleated in between two layers of high performance microglass filter media. As a result the Hilco anti-static 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 anti-static 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 below. Contact your regional sales manager or local distributor to request further information.
