Inthe International Standards Organization ISO established the compressed air quality standard to facilitate compressed air system component selection, design and measurement.

The remaining oil content should be 0. Lubricated compressors are typically less expensive to purchase and have a lower cost of ownership. This compressor technology presents no risk of lubricant migrating into the process air.

Air Quality Standards ISO 8573.1 & ISO12500

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 1200-1 point is required. Three separate test 125500-1 were constructed, each equipped with stainless steel piping, state of the art instrumentation and contaminant measurement equipment. The adsorption process will continue until the activated carbon media is fully consumed.

The purpose of this discussion is not to tip the scale toward either technology, but to address air treatment requirements in food processing applications. This moisture will spoil food products, cause pneumatic machinery failure and promote bacterial growth in the compressed air piping. Jul 14, Original Stories 0 Comments. Desiccant dryers- using activated alumina- will adsorb water vapor from the air most effectively, delivering ISO Particles may restrict flow through air jet nozzles used to clean food preparation surfaces or adversely affect the consistency of spray coatings applied on food products.

In total volume, condensed water vapor represents the majority of liquid contamination in a compressed air system. The most scrutinized and often discussed contaminant classified by ISO The ISO is designed to clear up this confusion and apply test standards to benefit air treatment manufacturers such iwo EXPEL by providing the means to commercially separate filter products through certifiable performance.

The challenge concentration selected shall appear in published technical data. The ISO air quality standards and ISO compressed air filter standards make the basis for air treatment product selection much easier.

Compressed air systems serving the food processing industry must maintain dry, 125001 free conditions mitigating the risk of micro-organism growth.

End users are given the choice of selecting from several air compressor technologies, some of which require lubrication in the compression chamber for cooling and sealing purposes, and others 1250-1 operate less lubricant in the compression chamber.

An easy to understand ISO The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their air system.

The vital piece of information which is missing when 12500- products is a challenge concentration. The ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters.

ISO – Filters for compressed air — Test methods — Part 1: Oil aerosols

So even though different manufacturers claim their products meet a certain purity 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 or identical on paper, can provide significantly different results when installed in a compressed air system.

Of the primary utilities employed in 122500-1 food-manufacturing environment, compressed air is the only utility generated by the end-user. Depending on the location of the compressor intake, ixo vapor levels in industrial areas may contain ppm of airborne hydrocarbon aerosols.

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. Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level.

The next time you sit down for dinner, take a good look at your food. ISO International Standards ensure that products are safe, reliable, tested and of good quality to ensure that all our products meet and International Standards. The ISO test standards will benefit air treatment manufacturers by providing the means to commercially separate filter products through certifiable performance.

Even a well maintained and routinely changed intake filter will allow solid particles to enter the air system. The standard defines critical performance parameters that will deliver certifiable filter performance information suitable for comparative purposes. Lubricant is only required for the bearings and timing gears, which is segregated from the compression chamber. You can trust EXPEL Filters to provide you with the clean compressed air you require wherever and whenever you need it.

In most cases, end users select compressed air system components by comparing technical data from various air treatment manufactures. In pneumatic control circuits, solids particles plug control valve orifices, affect accuracy of gauging and score air cylinders walls, causing leaks. The playing field is not level and consumers have become very confused.

Solid particulate must be removed from process air serving the food industry. Each is categorized and assigned a quality class ranging from class 0, the most stringent, to Class 9, the most relaxed.
