In a general industrial area, there are nearly 4, airborne particles per cubic foot of air. The ISO test standards will benefit air treatment manufacturers by providing the means to commercially separate filter products through certifiable performance. The ISO Air Quality standard is serving the 12050-1 well by raising end user awareness of how to measure and define the quality of compressed air.

This compressor technology presents no risk of lubricant migrating into the process air.

Jul 14, Original Stories 0 Comments. ISO provides guidance for the testing and methods for determining particulate filter removal efficiency, by particle size. Compressed air systems serving the food processing industry must maintain dry, moisture free conditions mitigating the risk of micro-organism growth. Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level. The remaining oil content should be 0.

In total volume, condensed water vapor represents the majority of liquid contamination in a compressed air system. The ISO air 125000-1 standards and ISO compressed air filter standards make the basis for air treatment product selection much easier.

However, this standard does not address how manufacturers are to test and rate the filters. A high efficiency coalescing filter capable of removing solids and liquids is recommended. The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their air system. When properly treated, compressed air is regarded as a safe, clean utility, as compared to other energy sources.

The vital piece of information which is missing when testing products is a challenge concentration. The purpose of this discussion is not to tip the scale toward either technology, but to address air treatment requirements in food processing applications.


Solid particulate must be removed from process air serving the food industry. ISO does not however address how manufacturers are to test and rate the filters they produce. We all benefit, appreciating that ISO, a global international standards organization, continues to refine its standards for the betterment of the compressed air industry and private sector. It is ultimately used to package, wrap, seal, palletize and label food products prior to storage or shipment.

ISO is a multi-part standard. 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.

Even a well maintained and routinely changed intake filter will allow solid particles to enter the air system. 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.

ISO determines the adsorption capacity and pressure drop of hydrocarbon vapor removal filters. Air treatment manufacturers present technical data in reference to ISO It provides power for pneumatically operated tools and equipment that renders meat products, aerates liquids and mixes granular ingredients. 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.

The standard defines critical performance parameters that will deliver certifiable filter performance information suitable for comparative purposes. Lubricant is only required 1250-01 the bearings and timing gears, which is segregated from the compression chamber.

The particulate filter will also enhance the service life of high performance coalescing isoo by minimizing solid loading. The new ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters. An easy to understand ISO Of the primary utilities employed in the food-manufacturing environment, compressed isso is the only utility generated by the end-user.

Lubricated compressors are typically less expensive to purchase and have a lower cost of ownership. The adsorption process will continue until the activated carbon media is fully consumed. Inthe Io Standards Organization ISO established the compressed air quality standard to facilitate compressed air system component selection, design and measurement. A well maintained scfm lubricated air compressor, with a conservative 4 parts per million carry-over, will add up to 4.

Filter manufacturer may elect to publish performance date at either of the two inlet concentrations. An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter.

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

This moisture will spoil food products, cause pneumatic machinery failure and promote bacterial growth in the compressed air piping. Filters shall be challenged by solid particulate in the range 0. ISO International Standards ensure that products are safe, reliable, tested and of good quality to ensure that all our products meet and International Standards.

At this level of dryness, bacteria will cease to grow. isi

Adsorption filters, utilizing an activated carbon medium, possess the polarity to attract hydrocarbon vapors from an air stream onto a porous surface. When this ambient air is compressed to 12500-11, the concentration of solid contamination will reach significant proportions. The end user determines which compressor design best meets the desired requirements.

ISO Standards – 12500 Air Quality

Water vapor enters the system through the intake of the air compressor. High quality compressed air is critical for providing food products that are not only cost effective to process 12050-1 also safe to eat.

Motion Industries Names New President. Lubricant free compressors generally have a higher initial cost and greater maintenance costs over the life cycle of the equipment.

The playing field is not level and consumers become confused. The most scrutinized and often discussed contaminant classified by ISO Desiccant dryers- using activated alumina- will adsorb io vapor from the air most effectively, delivering ISO
