Fluid Filter and Transfer Carts Buyers Guide

Lubrication excellence requires the right tools for the right job. Lubricant filter carts and transfer carts are vital tools that need to be designed for the task at hand. This buyers guide takes a look at what manufacturers offer and what options are available. Read more.

Guidelines for Selecting a Filter Media

Here are some things to consider when trying to decide whether to use fiberglass or cellulose filter media:

  More pores per square inch
  Consistent pore size and dirt holding capacity
  Higher dirt holding capacity
  Tolerant to high temperatures

Cellulose (Wood pulp)
  Large fiber diameter takes up space that could be used for particles
  Inconsistent pore size
  Absorbs water
  Subject to fatigue and high temperature failure

A Guideline for Machine Cleanliness Levels

As a general guideline, the cleanliness of an oil in a machine before starting operation should be two ISO classes below warning levels (targets) for that machine.

How to Contain Runaway Reservoir Contaminant Populations

While demographers busily count the world's population, manufacturers are fighting against growing particle populations within lube oil and hydraulic systems. Particles and people have little in common except that each has the propensity to increase rapidly in large numbers.

Comparatively, human populations around the globe are not dense. For example, the entire world's population is approximately 6.5 billion people. While a large number, it pales by comparison to the approximately 9.5 billion particles squeezed into a relatively clean 1,000-gallon reservoir of turbine oil. Read more.

Need Longer Filter Life?

From the The Practical Handbook of Machinery Lubrication

Never use coarse filters in an attempt to obtain longer filter life. If contamination levels are high and it is necessary to change filters often, obtain and install larger filters of the same quality to increase dirt capacity.
