How does an air 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.
How do you size an air compressor for a dryer?
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).
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 is the best air dryer for air compressor?
Best Desiccant Dryers: Overview
| Air Dryer | Thread Size | Link |
|---|---|---|
| Campbell Hausfeld Desiccant Air Dryer | 3/8″ | Amazon |
| Plews & Edelmann Desiccant Air Dryer | 1/2″ | Amazon |
| ALL Tool 3-Stage Desiccant Air Dryer | 1/2″ | Amazon |
| ATD Tools 5-Stage Air Dryer | 1/2″ | Amazon |
How big of an air dryer do I need?
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.
Why does my air compressor make so much water?
In simpler terms, air temperature, humidity, compressor size and required pressure will determine the water content coming out of the unit and potentially into the compressed air piping. Naturally, hot and humid air has a higher moisture content than cold air, it will result in more water coming out of the compressor.
What kind of air compressor does a compressed air dryer use?
Two-stage air compressor equipped with a JT type refrigerated compressed air dryer. Refrigerated dryers are the most common type of compressed air dryer.
How is the output of a compressed air dryer processed?
In most cases, the output of the compressor is processed through a primary dryer or system dryer. In cases where higher quality air is required the output of the primary dryer is further processed through a secondary dryer or polishing dryer. A deliquescent dryer delivers a dew point suppression that fluctuates with air temperature.
How is a point of use air dryer sized?
Air Dryers are normally sized by the maximum output of the air compressor (when installed within the compressor room). Point of use air dryers are used for a variety of air drying applications, we recommend sizing point of use dryers by the end air demand.
Why is water vapor removed from a compressed air dryer?
As the compressed air cools, water vapor condenses into the tank (s), pipes, hoses and tools that are downstream from the compressor. Water vapor is removed from compressed air to prevent condensation from occurring and to prevent moisture from interfering in sensitive industrial processes.
