Why Should I Change my Compressed Air Filter Element?
Submitted by Mark White || Parker
Over 90% of manufacturing facilities world-wide use compressed air as part of their manufacturing process. However, this powerful utility is not without its problems, in the form of compressed air contamination. It is therefore common practice to install compressed air filters as part of a purification system to ensure contaminants are reduced and the system operates in a safe, efficient and cost effective manner.

Learn the Anti-Corrosion Code
Submitted by Clara Moyano || Parker Hannifin
Probably the most significant trend in the instrumentation products world today is the design of increasingly corrosion-resistant systems. Led by oil and gas companies, instrumentation and piping engineers are now focusing far more attention on the materials used to fabricate valves, manifolds and tubing systems. In the offshore project world, for example, Parker Hannifin is currently seeing exponential growth in the use of 6Mo in preference to traditional 316 stainless steel. So, why are so man...

Choosing the Correct Chemical Metering Pump for your Application
Submitted by Mike Price || Walchem
Selecting the correct chemical metering pump can be a daunting task because of the variations and types of chemical pumps available. In order to pick the best metering pump for the application you will need to consider several factors. For the sake of simplicity, we will limit our discussion to pumps that deliver no more than 50 gph and pressures of less than 250 psi.

Taking Fluid Cleanliness to the Next Level with Permanent Offline Filtration
Submitted by Des-Case
In recent years, portable filtration units, often referred to as filter carts, have become a common tool in the lubrication professional's arsenal. Increasing demand for these systems has led to the development of a wide range of new products and driven down prices, which is a good thing. When filter carts first came onto the scene they were primarily used by service providers for decontaminating large systems. These early models were typically designed for low viscosity oils in large volume sys...

Filter Ratings
Submitted by Tim Tritch
The purpose of a filter is to remove contaminants from a fluid stream either completely, or at least down to a given rating or specification. Filters are used to help control contaminants and are rated according to their ability to remove these contaminants from a liquid, gas or air stream. There are different methods in which the performance of filters are specified.

Valve Aerodynamic Noise Reduction Strategies
Submitted by Jon Monsen, Ph.D., Valin Corporation
There are two strategies for reducing control valve noise:
1. Source control, that is doing something to the valve to make it less noisy, and
2. Path control, that is doing something to prevent the noise from reaching the people who would be bothered by it.
