Dynamic Filter Efficiency

What is Dynamic Filter Efficiency?

Dynamic Filter Efficiency matches filter testing with real-life conditions.

All hydraulic and lube systems have a critical contamination tolerance level that is often defined by, but not limited to, the most sensitive system component such as servo valves or high speed journal bearings. Defining the ISO fluid cleanliness code upper limit is a function of component sensitivity, safety, system criticality and ultimately getting the most our of hydraulic and lube assets.

Understanding ISO Codes

By Dustin Flynn on Thu, Feb. 25, 2021

ISO Cleanliness Codes Explained

The ISO Cleanliness Code (per ISO4406-1999) is used to quantify particulate contamination levels per milliliter of fluid at 3 sizes - 4µ, 6µ, and 14µ. It is expressed in 3 numbers (example 19/17/14) where each number represents a contaminant level code for the correlating particle size. The code includes all particles of the specified size and larger. Screen Shot 2021-02-23 at 2.50.37 PM It is important to note that each time a code increases, the quantity range of particles is doubling. Inversely, as a code decreases by one the contaminant level is cut in half.

How to Keep Your Diesel Clean

By Jim Harlan on Fri, May. 17, 2013

We've all been there -- the power goes out and instant panic sets in. Until you remember that you have a backup generator for just this type of situation. You rely on that generator to run your servers, emergency equipment or entire facility.

But if you haven't tended to the diesel fuel in your storage tank, it could easily be contaminated with water and particulate, causing failure and requiring expensive repairs.

One way to keep your diesel clean and dry is to replace the fuel at a set interval. This will ensure that your generator has all it needs to function in case of an emergency; however, it can prove to be costly.

What if we told you that you didn't have to replace the diesel, even if it were contaminated?
