Air Water

What is Contaminating Your Compressed Air?

Clean, dry, oil free compressed air and gas is a basic need for many industries.
One drop of unwanted oil can cause an entire automated process to malfunction.  It can cause seals in pneumatic valves and cylinders to swell, resulting in sluggish operation - or in worst cases, complete seizure of moving parts.

 

3 things that can contaminate your compressed air system and ruin your product or processes.
1)  Solid particles come from ambient air contaminants like dust and from rusted, oxidized pipework. They will cause pneumatic equipment to malfunction, cause instrument and control failures, and contaminate end products.

 

2) Condensed water droplets come from the humidity in ambient air. Water will oxidize pipework and pneumatic equipment, ruin paint finishes and end products.

 

3) Liquid oil and oil vapors are introduced by compressor lubricants and by hydrocarbon vapors present in ambient air. Oil-free compressed air is particularly important in food and pharmaceutical processes.

 

Compressed Air Filters effectively and efficiently remove solid particles, remnants of oil, water mist and other liquid from compressed air and gas which can...
-wear out pneumatic machinery
-block valves and orifices, causing high maintenance
-corrode piping systems which cause costly air leaks
-result in abrupt equipment stoppages, lost product, time and money

 

How to clean your Compressed Air...

 

Depending on the level of air purity required, different levels of filtration and types of filters are used.  Filters are used in
conjunction with other "filtering equipment" - such as a Water Separator or Compressed Air Dryer- to help remove harmful contaminates from your system.

 

General Purpose Filters - also called "particulate filters" are used  to remove solid particles. Oil and Oil Vapor Removal
Filters - also called "coalescing-type filters" are used to remove oil and vapors.

 

A particulate filter is recommended after a desiccant-type dryer to remove desiccant fines.
A coalescing-type filter is recommended before a desiccant type dryer to prevent fouling of the desiccant bed.
Additional filtration may also be needed to meet requirements for specific end uses.
Compressed air filters downstream of the air compressor are generally required for the removal of contaminants, such as particulates, condensate, and lubricant.

 

Listed below are types of filtration equipment available in today's market. The specifications offered are from Champion Air Compressors as a market example.

Performance*: Handles bulk liquid water inlet loads to 100 ppm w/w and provides 0.0008 ppm oil aerosol removal and 0.01 micron solid particulate separation.

 

Oil Vapor Removal Filter
Installation: Afterfilter to high efficiency liquid oil removal filters for true oil-free applications.
Design: Two-stage filtration with a generously-sized first stage of a stabilized bed of carbon particles which remove the majority of the oil vapor. Second stage has multiple layers of fiber media with bonded microfine carbon particles which remove the remaining oil vapors. Includes an outer-coated, closed cell foam sleeve which prevents fiber migration.
Performance**: No liquid should be present at filter inlet. Provides 0.003 ppm w/w oil (as a vapor) removal and 0.01 micron solid particulate separation.

 

* Filter efficiencies have been established in accordance with CAGI standard ADF400 and are based on 100°F (38°C) inlet temperature
** Filter efficiency has been established in accordance with CAGI standard ADF500 and is based on 100°F (38°C) inlet temperature

 

Filtration only to the level required by each compressed air application will minimize pressure drop and resultant energy consumption.
Elements should also be replaced as indicated by pressure differential to minimize pressure drop and energy consumption, and should be checked at least annually.
You can customize your air treatment applications by choosing the combination of dryers, filters, and separators that give you the level of clean air or gas that you need.

 

Who establishes quality industry standards for filters?

 

ISO 8573.1 was developed in 1992 by ISO (International Organization for Standardization) to help plant engineers specify desired compressed air quality globally by providing “Quality Classes” for solid particulates, humidity and oil. Quality classes provide engineers with an internationally accepted unit of measure.

 

A typical pharmaceutical plant, for example, would have a compressed air specification of ISO Quality Classes 1.2.1.  This is equivalent to 0.1 micron particulate filtration, -40°F (-40°C) dew point, and 0.008 ppm (0.01 mg/m3) oil filtration. No matter what language is spoken and what unit of measure is used, using ISO 8573.1 Air Quality Classes ensures that your factory will get the compressed air quality you specified.

What does it mean about the air/water/environment in my apartment if ...?

Every time I leave water sit out in a container of any kind (plastic cup, plastic water bottle, metal cat water bowl), it fills all up with tiny bubbles clinging to the sides of the container. I've never had such bubbleage in previous apartments. What do they mean? Is there something weird going on with the water or temperature or air quality in my apartment?

The only thing present in your appartment thats causing what u said is an 'Air Mixer/Aerater' present inside the tap/faucet.

It causes the water emerging from the tap/faucet to cantain more dissolved air and more air bubbles in the water.
So place the water in any container bubles will stick out at the edges.
There isn't something weird going on with the water or temperature or air quality in your apartment

New Hampshire Scientists Urge GOP Presidential Hopefuls to Recognize “Overwhelming Evidence” of Climate Change (Think Progress)

I just got back from visiting family in New Hampshire for the holidays,
narrowly missing the rush of hot air spewed by presidential candidates as they
move eastward for the state's upcoming primaries after tomorrow's Iowa
caucuses. Or maybe they'd been visiting the state too much already. Because
when I got home, instead of our [...]
