A compressed-air dryer and filter regulators installation supplies clean, dry compressed air to equipment that often utilize the air as motive power. Moreover, filtering and drying the air keep the equipment from damage from contaminants in the air such as liquid water, water vapor, dust from the atmosphere, scale from the inside of the pipes, and breakdown products from the lubricants in the air compressor. After knowing this information, we can get some knowledge and considerations about how to make filter, and then we can conclude some skills about how to make filter and then can start our specific procedure about how to make filter.
For the specific procedure about how to make filter, and then the compressed-air dryer and its connected filter are chosen based on several considerations about how to make filter. Moreover, it starts with the volume and pressure of the air to be cleaned and dried, and then look at the environment the dryer and filter will be put in: what are the average temperatures around us; will they be subject to vibration? And we have another consideration about how to make filter is how dry, that is, how low the dew point, of the compressed air supply must be, and the existence of maintenance and reliability of operation is other considerations. What’s more, another problem is whether continuous operation of the compressed-air system including pneumatic actuators is needed.
Before we seek the deep information about how to make filter, we should know the types of compressed-air dryers: the single-tower dryer, the regenerative dryer and the refrigerated dryer.
For the single-tower dryer, it is full of a deliquescent desiccant that dissolves as it absorbs water vapor. Moreover, the liquefied desiccant must be drained frequently and replaced by fresh desiccant, but this is often done only a several times a year, and the single-tower dryer does not need any additional power supply.
For the regenerative or twin-tower dryer, it uses one tower to dry the compressed-air flow while the other tower is having the moisture in its desiccant removed. What’s more, and heat or air has dried the desiccant. The regenerative dryer is used when the flow of compressed air is continuous.
For the refrigerated compressed-air dryer, it makes use of a refrigeration unit to condense the water vapor in the compressed air and a water separator to remove the liquid water. What’s more, a refrigerated dryer can offer a supply of compressed air with a dew point between 35 and 38 degrees Fahrenheit. For most of refrigerated air dryers are used to supply air to pneumatic temperature control systems like pneumatic actuator, and they can do very well in an indoor, clean, temperature-controlled environment.
When we select a type of compressed-air dryer, we should focus on a check of its use, location, the power available and the pneumatic actuator. If more than one type will do the job, then preliminary cost, reliability and maintenance costs are additional considerations.
Compressed-air filters keep the dryer and the equipment using compressed air from damage, and then there are two types of filter factor, particulate and coalescing.
Particulate filters remove particles not removed by the air compressor pre-filter and other particulate matter. Moreover, coalescing filters bring contaminants together so they can be gotten by the filter factor.
