It should be capable of removing solid and liquid aerosols 0.

In most cases, end users select compressed air system components by comparing technical data from various air treatment manufactures. Ingested contamination in the form of water vapor, solid particulate and hydrocarbon vapor must be addressed regardless if the compressor is lubricated or free from lubricant. The vital piece of information which is missing when testing products is a challenge concentration. The playing field is not level and consumers have become very confused.

The older ISO Air Quality standard is serving the industry well by raising end user awareness of how to measure and define the quality of compressed air used. The end user-user is responsible for defining the air quality required for their particular application or process.

In a general industrial area, there are nearly iiso, airborne particles per cubic foot of air. Compressed air is a vital energy source and is utilized in multiple operations in a food processing facility. 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.

To achieve the recommended ISO Since compressed air used in food processing operations may come in direct contact with the food, a compressed air dryer producing a sub-zero pressure dew point is required.

In total volume, condensed water vapor represents the majority of liquid contamination in a compressed air system. The most scrutinized and often discussed 15200-1 classified by ISO However, this standard does not address how manufacturers are to test and rate the filters. The ISO air quality standards and ISO compressed air filter standards make the basis for air treatment product selection much easier. When this ambient air is compressed to psig, the concentration of solid contamination will reach significant proportions.

ISO Standards – Air Quality

Isk determines the adsorption capacity and pressure drop of hydrocarbon vapor removal filters. Jul 14, Original Stories 0 Comments. The challenge concentration selected shall appear in published technical data. The next time you sit down for dinner, take a good look at your food.

ISO provides guidance for the testing and methods for determining particulate filter removal efficiency, by particle size. The standard also determines that air quality shall be designated by the following nomenclature:. 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.

Lubricated compressors are typically less expensive to purchase and have a lower cost of ownership. It is ultimately used to package, kso, seal, palletize and label food products prior to storage or shipment.

Air Quality Standards ISO 8573.1 & ISO12500

A high efficiency coalescing filter capable of removing solids and liquids is recommended. Compressed air systems serving the food processing industry must maintain dry, moisture free conditions mitigating the risk of micro-organism growth. The ISO is designed to clear up this confusion and apply test standards to benefit air treatment manufacturers such 12500-11 EXPEL by providing the means to commercially separate filter products through certifiable performance.

An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter. Solid particulate must be removed from process air serving the food industry. The adsorption process will continue until the activated carbon media is fully consumed. Water vapor enters the system through the intake of the air compressor.

ISO Standards – 12500 Air Quality

Even a well maintained and routinely changed intake filter will allow solid particles to enter the air system. Not all products claiming compliance with the ISO standards are tested in the same way. The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their 12500- system.
