Factors Governing the Selection of Compressed Air Filters

Image
Compressed air filters are designed to remove air borne particles from a moving, pressurized air stream. Compressed air purification equipment is essential to all modern production facilities; at its best, the equipment should provide the optimum balance between air quality and low operating cost. There are numerous manufacturers offering products for the filtration and purification of air; compressed air filter costs cover a wide range - but initial purchase cost cannot always indicate the effectiveness of a piece of equipment. In assessing the suitability of the product, the purchaser will want to assess: delivered air quality required by their application environmental impact of use overall cost of operation over the life of the equipment One way to make these assessments is to compare the performance standards of the different manufacturers' products according to the standards that apply via ISO (the International Standards Organisation) under which there are a series of...

What is Contaminating Your Compressed Air?

"Clean, dry, oil free compressed air and gas is a basic need for many industries" One drop of unwanted oil can cause an entire automated process to malfunction. It can cause seals in pneumatic valves and cylinders to swell, resulting in sluggish operation - or in worst cases, complete seizure of moving parts. Three things that can contaminate your compressed air system and ruin your product or processes. 1) Solid particles come from ambient air contaminants like dust and from rusted, oxidized pipework. They will cause pneumatic equipment to malfunction, cause instrument and control failures, and contaminate end products. 2) Condensed water droplets come from the humidity in ambient air. Water will oxidize pipework and pneumatic equipment, ruin paint finishes and end products. 3) Liquid oil and oil vapors are introduced by compressor lubricants and by hydrocarbon vapors present in ambient air. Oil-free compressed air is particularly important in food and pharmaceutical...

Compressed Air Filters

Compressed air filters are widely used in the industrial arena. They are used to remove water, oil, oil vapor, dirt and other contamination from a compressed air supply. Compressed air filters are used to control and cool various forms of industrial instruments. A pneumatically operated machine suffers serious effects caused by dirt particles, oil carryover and moisture. In most of the applications, contamination of the air supply could lead to serious performance degradation and most likely will increase the maintenance cost in terms of repairs. The result of this is that productive time is lost. The only way to cut down the costs and increase the performance is to properly maintain compressed air filters. There are different types of compressed air filters. All of them are built in a way to remove the oil and other contamination from the air supply. Some have special features that make them more effective in specific applications. Coalescing oil removal filters are able to remove oil...
