Investing in effective hydraulic filters could save you a fortune in downtime.

Dirt in a hydraulic system is a potential killer, and without the correct hydraulic filters the dirt will silently destroy your investment. The dirt we’re talking about is usually so fine that you’d battle to see it with the naked eye.

But by effectively controlling the level of contaminants (dirt) to acceptable levels you can reduce system failure by as much as 75%.

That is extremely important when you consider the

Have you ever driven through a deep puddle of water only to have your hapless engine lock solid after ingesting a cylinder full? This is known as hydraulic lock and is an expensive illustration of hydraulic power which hydraulic oils convey.

In this article I’ll be focusing on hydraulic oils as opposed to brake fluids, which are a very specialised sub category.

Functions and properties
The primary function of hydraulic oils is to convey power. However, there are other important functions of modern hydraulic oils. These the major functions of hydraulic oil and the properties of the fluid that affect its ability to perform that function:

Hydraulic Performance properties
• Low compressibility (high bulk modulus)
• Fast air release
