How do I choose an air dryer for my air compressor?
The following information is required to properly select an air dryer:
- Maximum air flow in standard cubic feet per minute (scfm)
- Inlet air pressure.
- Inlet air temperature.
- Ambient air temperature (and water temperature if condenser is water-cooled)
- Desired pressure dew point.
- Utilities required.
- Installation.
What are the different types of air dryer?
The four primary types of air compressor dryers are:
- Refrigerated dryers.
- Desiccant dryers.
- Chemical dryers.
- Membrane air dryers.
How does a compressor air dryer work?
A compressed air dryer is a piece of equipment designed to separate water vapor or moisture (de-humidify) from industrial process air. In the typical system, a compressor draws in humid air and compresses it, which raises the air temperature and then cooling the air condensing water vapor out of the unit.
What size dryer do I need for my compressor?
If you wanted a properly sized dryer from one example supplier, you should add 51% for the high inlet temperature, about 5% for the lower pressure and another 16% for high ambient temperatures. This would result in a dryer rated at about 500 x 1.51 x 1.05 x 1.16 = 920 cfm.
How big air dryer do I need?
To figure out the right-sized dryer, divide the total flow by the total correction factor: 200 cfm / 0.861= 232 cfm (at standard conditions). Now, you can look at the dryers’ stated capacity on the dryer literature (excerpt shown below) and see which one will dry 232 cfm effectively.
What is a desiccant dryer for an air compressor?
A desiccant air dryer system purifies compressed air by absorbing moisture. You can find these systems in any industrial application in which reliable equipment and exceptional quality control is necessary. Quincy Compressor manufactures a full line of desiccant air dryer systems.
What is air dryer in air compressor?
The purpose of air dryers is to suppress the dew point of your compressed air by removing water from it. Compressed air can contain moisture, which, under the right conditions, can reach the dew point temperature and condense into a harmful liquid.
How do you get moisture out of compressed air?
Common practices to remove moisture from compressed air include:
- Draining the tank.
- Using a water trap and filter regulator.
- Using a refrigerated air dryer.
- Using a desiccant air dryer.
- Using a deliquescent air dryer.
- Through piping system air drying.
- With the storage tank cooling method.
- Through absorption drying.
How long do desiccant dryers last?
2 to 3 years
For heat regenerated dryers the desiccant should last 2 to 3 years. Desiccant can be visually inspected to look for discoloration and oil contamination. We also offer a free desiccant testing service.
What is the most commonly used method for removing moisture vapor from compressed air?
compressed air dryers
Most manufacturers use compressed air dryers as one of the methods for removing moisture. Air exiting a compressor is heated and 100 percent saturated with water.
Why do I need dryer for my air compressor?
Air Inlet As air enters,the internal cap forces it into a downward spiral. Just be sure to size the inlet appropriately for your compressor.
How to select an industrial air compressor?
Look at the horsepower (HP) of the air compressor. A common range for horsepower on an air compressor is between 1.5 and 6.5 HP.
Do you need an air dryer for your compressor?
Every air compressor needs an air dryer to keep the machine running smoothly and without issues. All compressors create water that can be drained but remain an aerosol inside the machine. If this water is not separated, it can damage and corrode parts of the air compressor.
What is the best compressed air dryer?
0 F to 80 F – Deliquescent air dryer
