Why is air treatment necessary?


Compressed air treatment is a method that dehumidifies and cleans after it leaves the air compressor. This is done using an air dryer and an additional filter beyond the air filter found in a compressor. Air is always contaminated with solid particles such as dust, sand, soot, salt crystals and water as it leaves the compressor. An effective compressed air treatment system lowers the dew point of the air and takes out the elements that may harm equipment downstream of the compressor and dryer. Remember the higher the ambient temperature is, the higher the ability to hold moisture. Water contamination can also lead to microbial contamination, corrosion, blocked or frozen valves, cylinders, air motors and tools and premature wear/failure of equipment. Water contamination of compressed air systems can reduce production efficiency and increase manufacturing costs.



Who uses air dryers?

Both refrigerated and desiccant dryers are needed in many industrial applications to produce/protect final products, as well as to protect much of the pneumatic equipment that is used in many industrial facilities. Food/beverage packaging and manufacturing companies use dryers to prevent their actuators and assembly machinery from rusting or collecting moisture in the lines that prevents clean compressed air from flowing. Dryers are also used in textiles to keep fabrics free of moisture and to aid in the texture of produced products. Many electronics manufacturers need high levels of dry air so that humidity will not transfer over to the production of computers, cell phones, televisions, etc. These same industries often use moisture separators, oil-water separators and aftercoolers to further aid in the drying process, as well as removal of contaminants from any compressed air flow. Dust, dirt or other small particles are present in compressed air until they are removed by using filters, separators and mist eliminators. Air treatment is necessary in almost all compressed air applications. From food manufacturing, to brewing beer, to building electronics, having dry compressed air is a must to prevent product and equipment damage.

Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for maintenance can have potentially disastrous consequences. …


The air dyer is one of the most ignored cooler in the system. A dirty condenser will cause water in the lines, or worse it will cause complete dryer failure. …


Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will also save you money as early as month one adding that savings to your bottom line. …


A question that is occasionally asked by our customers to Ash Air is 'what is the cost of compressed air?'Β  This article looks at the product costs involved with compressed air, as well as minimising the energy cost of compressors and cost allocation. When looking at these factors, we need to realise what causes dropped efficiency of your compressor, leading to increased costs of compressed air. …


You may have great fall protection measures in place to keep employees safe when working at height, but what about their co-workers below? Dropped tools and other falling objects are a major hazard – and one that isn’t always fully addressed.Β  …


Providing a safe working environment for operators is essential, especially when using pneumatic tools and compressed air. If there is a failure in the air network and the hose is not adequately clamped, the resulting whiplash could be devastating. Failure to follow best practice can result in injuries, associated production downtime and decreased productivity. …


A common questions asked is why do I need an air dryer for my compressor? Typically, air compressors produce water, and although the water can be drained, there can still be aerosol and vapour droplets that are present. This is because water cannoet be compressed. Water can damage your compressor by corroding the valves, pipes and machinery controls, which will cost you time and money to resolve. In the long run, the cost of a new compressor is a small price to pay compared to the loss of production that could potentially arise due to water damage in your compressor.
