Of the ten major contaminants found in compressed air, nine are removed using filtration technology, however, are all compressed air filters the same?
Compressed air purification equipment is essential to all modern production facilities. It must deliver uncompromising performance and reliability whilst providing the right balance of air quality with the lowest cost of operation. Today, many manufacturers offer products for the filtration and purification of contaminated compressed air, which are often selected only upon their initial purchase cost, with little or no regard for the air quality they provide, the cost of operation throughout their life or their environmental impact. When purchasing purification equipment, delivered air quality, the overall cost of ownership and the equipment’s environmental impact must always be considered.
The Parker domnick hunter Design Philosophy
Parker domnick hunter has been supplying industry with high efficiency filtration
and purification products since 1963. Our philosophy "Designed for Air
Quality & Energy Efficiency" ensures products that not only provide the
user with clean, high quality compressed air, but also with low lifetime costs
and reduced CO2 emissions.
Cost Effective System Design
The quality of air required throughout a typical compressed air system will
vary depending upon application. Treatment of the compressed air at only one
point alone, for example the compressor room; is not enough and it is highly
recommended that the compressed air is first treated prior to entry into the
distribution system (to a quality level suitable for protecting air receivers
and distribution piping) and then at the point of use, with specific attention
being focussed on the application and the level of air quality required. This
approach to system design ensures that air is not “over treated”
and provides the most cost effective solution to high quality compressed air.
The use of the ISO 8573-1:2001 Air Quality Standard provides the system engineer
with a simple method of specifying the air purity required at each point in
the compressed air system. Using this standard allows Parker domnick hunter
to quickly and easily select products from its comprehensive range of purification
products to exactly match your system requirements and ensure both your capital
and operational costs are kept to a minimum.
The following table highlights the Parker domnick hunter filtration and drying
products required to achieve each air purity classification shown in ISO 8573-1:2001.
