However, this standard does not address how manufacturers are to test and rate the filters. Presenting product data in this way should allow users to easily compare the performance of purification products from different manufacturers and cost effectively meets the air quality requirements of their application.
Solid particulate must be removed from process air serving the food industry. Filter manufacturer may elect to publish performance date at either of the two inlet concentrations.
Compressed air is a vital energy source and is utilized in multiple operations in a food processing facility. Inthe International Standards Organization ISO established the compressed air quality standard to facilitate compressed air system component selection, design and measurement.
Filters shall be challenged by solid particulate in the range 0. Even a well maintained and routinely changed intake filter will allow solid particles to enter the air system. Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level.
Food processors maintain a social responsibility for upholding the quality of their products and that accountability begins with the selection of compressed air system components. Lubricant is only required for the bearings and timing gears, which is segregated from the compression chamber.
Air Quality Standards ISO 8573.1 & ISO12500
Motion Industries Names New President. The remaining oil content should be 0. Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level. Spores, pollen and bacteria are less than 2 micron in size. ISO provides guidance for the testing and methods for determining particulate filter removal efficiency, by particle size.
An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter. An easy to understand ISO ISO – Testing of filters for oil aerosol removal performance ISO — Testing quantifies vapour removal capacity of adsorption filters ISO — Testing for solid contaminant removal ISO — Testing of water-removal efficiency and operational pressure drop You can trust EXPEL Filters to provide you with the clean compressed air you require wherever and whenever you need it.
This means the end-user directly influences the quality of this energy source. The end user-user is responsible for defining the air quality required for their particular application or process. The ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters. The new ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters. This moisture will spoil food products, cause pneumatic machinery failure and promote bacterial growth in the compressed air piping.
Hydrocarbon vapors, the primary component of fossil fuel combustion, will condense in a piping system when cooled forming a liquid contaminant. Depending on the location of the compressor intake, oil vapor levels in industrial areas may contain ppm of airborne hydrocarbon aerosols.
Air Quality Standards ISO & ISO | Compressed Air Best Practices
The standard defines critical performance parameters namely, inlet oil challenge, inlet compressed air temperature and pressure measurement techniques that will deliver certifiable filter performance information suitable for comparative purposes. The challenge concentration selected shall appear in published technical data.
At this level of dryness, bacteria will cease to grow. The particulate filter will also enhance the 12500–1 life of high performance coalescing filters by minimizing solid loading. Desiccant dryers- using 1200-1 alumina- will adsorb water vapor from the air most effectively, delivering ISO In most cases, end users select compressed air system components by comparing technical data from various air treatment manufactures.
The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their air system.
This may seem like a lot of particulate matter, but keep in mind, a solid particle 40 um in size is barely visible to the naked eye. So even though different manufacturers claim their products meet a certain 12500-11 class, they will most likely have been tested with differing concentrations of contamination entering the product and as challenge concentrations are rarely included in technical data, filter performance which may look similar 1250-1 identical on paper, can provide significantly different results when installed in a compressed air system.
In a general industrial area, there are nearly 4, airborne particles per cubic foot of air. The standard defines critical performance parameters that will deliver certifiable filter performance information suitable for comparative purposes.
The standard also determines that air quality shall be designated by the following nomenclature:. The playing field is not level and consumers have become very confused.
