what is contaminating your compressed air?

by:AIRWOLF     2020-06-13
Clean, dry, oil-free compressed air and gas are the basic needs of many industries.
A drop of unwanted oil can cause a failure in the entire automation process.
It causes expansion of seals in pneumatic valves and cylinders, resulting in slow operation
Or in the worst case, completely seize the moving part.
3 things that will pollute your compressed air system and destroy your product or process. 1)
The solid particles come from environmental air pollutants such as dust and rust oxidation pipes.
They cause trouble with pneumatic equipment, cause trouble with meters and controls, and pollute the final product. 2)
Condensation water droplets come from the humidity in the ambient air.
The water will be oxidized to pipes and pneumatic equipment, damaging the paint finish and the final product. 3)
The hydrocarbon steam present in compressor lubricating oil and ambient air is introduced into liquid oil and oil steam. Oil-
Free compressed air is particularly important in food and pharmaceutical processes.
Compressed air filters can effectively remove solid particles, oil, fine mist and other liquids from compressed air and gas. . . -
Pneumatic mechanical wear-
Blockage of valves and openings resulting in high maintenance-
Corrosion of piping systems, resulting in expensive air leakage
How to clean compressed air can cause the equipment to stop suddenly, the product is lost, the time and money are lost. . .
Depending on the desired level of air purity, different levels of filtration and filter types are used.
Filters are used with other \"filter devices-
For example, a water separator or a compressed air dryer-
Help remove harmful pollutants from the system.
Universal filter
Removal of solid particles is also known as a \"particle filter \".
Filter for oil and oil steam removal-
Also called knot
\"Type filter\" for oil and steam removal \".
Particle filter is recommended after desiccant
Dryer for the removal of desiccant. A coalescing-
To prevent dirt from the desiccant bed, it is recommended to use the type filter before the desiccant dryer.
Additional filtering may also be required to meet specific end-use requirements.
Compressed air filters downstream of the air compressor generally require the removal of contaminants such as particles, condensate and lubricants.
The types of filter devices available in today\'s market are listed below.
As an example of the market, the specifications provided come from the champion air compressor.
Installation of water separator: after air compressor (or a stand-alone)
Design of rear cooler: 1-
Stage filtration with two stainless steel orifice plates.
The labyrinth airflow path removes liquid water by forcing sudden directional changes.

Flow efficiency as low as 5% of rated flow.
Separator/filter installation: After the air compressor (or a stand-alone)
Post cooler or pre-filter designed as a freeze dryer: Two-
Filter with the first stage of two stainless steel orifice plates to remove the bulk liquid and solid particles by 10 microns.
The second phase has entered-
Capture the solid particles into a deep poly fiber medium of 3 microns.

Universal filter installation: 1 micron particle pre-filter for refrigerated dryer and efficient oil removal filter. Design: Two-
Filter with the first stage of multi-layer fiber media, pre-filterfilter the air.
In the second stage, there is an in-depth cohesive fiber medium that aggregates petroleum aerosol and removes finer particles to 1 micron.
Performance *: handling bulk liquid inlet load to 2,000 ppm w/w, providing 1 micron solid particle filtration and 1 ppm oil removal.
Dry particle filter installation: dry solid particle back filter design for heat-free desiccant dryer: Double-
Filter with life stage-
Extend the external/air flow with a first stage alternating layer of fiber media and a media screen that captures large particles.
The second phase captures finer particles.
Not designed for any liquid loading.
Performance *: Provides 1 micron solid particle filtration of desiccant dust.
Efficient oil removal filter installation: pre-filter for desiccant and membrane dryer, rear filter for freeze dryer and bracket
Remove oil separately at this pointof-
Use compressed air. Design: Two-
Filter with the first stage of the multi-layer fiber medium, pre-filter the air.
The second phase has entered-
Deep poly fiber media that aggregate petroleum aerosol.
Including an external
Closed foam sleeve with coating.
Performance *: handle bulk liquid inlet load of 1,000 ppm w/w and provide 0.
008 ppm oil Aerosol removal and 0.

Maximum efficiency oil removal filter installation: pre-filter desiccant and membrane dryer with C- class pre-filter, oil-
Free Air app. Design: Two-
Stage filtration with coating Phase 1, closed-
Foam sleeve as pre-filter and flow distributor.
The second phase has entered-
Deep cohesive fiber media that condense fine oil aerosol together.
Includes an outer coated closed foam sleeve.
Performance *: handle bulk liquid inlet load of 100 ppm w/w and provide 0.
Oil Aerosol removal and 0 for 0008 ppm.
Separation of 01 Micron solid particles.
Oil steam removal filter installation: efficient liquid oil for real oil removal filter rear filter for filter-
Apply for free. Design: Two-
Filter with generous stages-
The first phase of the carbon particle stabilization bed removes most of the oil steam.
The second stage has a fiber medium with multiple layers of small carbon particles with adhesive, which remove the remaining oil vapor.
Including an external
Coated closed foam sleeve to prevent fiber migration.
Performance *: there should be no liquid at the filter inlet. Provides 0.
003 ppm w/w oil (as a vapor)removal and 0.
Separation of 01 Micron solid particles.
* Filter efficiency is established according to the CAGI standard ADF400, based on 100 °F (38°C)
Inlet Temperature * filter efficiency is established according to the CAGI standard ADF500, based on 100 °F (38°C)
The inlet temperature is filtered only to the level required for each compressed air application, which will minimize the pressure drop and the resulting energy consumption.
Components should also be replaced in accordance with the differential pressure indication to minimize pressure drop and energy consumption and to check at least once a year.
You can customize your air handling application by selecting a combination of dryer, filter and separator that can provide you with the clean air or gas you need.
Who established high quality industry standards for filters? ISO 8573.
1 is ISO in 1992 (
International Organization for)
By providing a \"quality grade\" for solid particles, humidity and oils, it helps factory engineers to specify the required compressed air quality worldwide.
The quality course provides engineers with an international standard of measurement.
For example, a typical pharmaceutical factory will have a compressed air specification for ISO quality Grade 1. 2. 1.
This is equivalent to 0.
1 micron particle filtration ,-40°F (-40°C)
Dew point, 0. 008 ppm (0. 01 mg/m3)oil filtration.
Use ISO 8573, whatever language is spoken, what unit of measurement is used.
1 Air quality grade ensure your factory gets the compressed air quality you specify.
