Non Spark Discharge Elements

Hy-Pro NSD element and media technology is optimised to prevent spark discharge and minimise potential energy in bearing lubrication and hydraulic control systems.

For some, the answer to preventing element sparking and high potential energy is to use coarse strainer type filters (stat-free) in the main bearing lube filter duplex. Although this may prevent sparking it renders the main bearing lube filter assembly useless in preventing catastrophic bearing failure due to contamination. Independent lab analysis proves that even Hy-Pro high-efficiency 3-micron absolute NSD elements are resistant to spark discharge.

With Hy-Pro NSD elements, any reduction in thermal sparking events will have a positive impact by reducing anti-oxidant additive depletion and extending useful fluid life. Field test data has also shown that Hy-Pro NSD elements even reduce or stabilise varnish potential values.
