Hydraulic Water Filter vs. Water Separator

Hydraulic systems need filtration for overall system care.

Hydraulic oil resides in many different mechanical systems, from automobile brakes to construction machine boom arms. The hydraulic oil should remain clean by means of filtration within the system, as well as by staying out of local groundwater.

Hydraulic Water Filter

A hydraulic water filter is a trapping device mounted to a hydraulic system. The filter captures any infiltration of water, as well as dirt and debris within the hydraulic system. Most hydraulic water filters have a pressure gauge attached to its assembly for alerting workers to a clogged or filled filter.

Water Separator

In contrast, a water separator is a machine that allows oils, such as hydraulic, to rise through a filter, away from waste water. One drawback to this system is that not all oil particles will rise through the separator device; only particles larger than 10 micrometers will pass upward, leaving the smaller particles to flow back with the waste water.

Water Filtering Significance

Both the hydraulic water filter and the water separator aid in saving hydraulic oil from contamination, as well as saving on hydraulic oil supply. Businesses save money by using saved and recycled hydraulic oil in their machinery.
