Air dryers are important for many industries when they need to make the air dry. An air dryer takes away wetness from pressed air. This helps prevent harm and rust to the equipment it goes to. The thing that sucks up water from compressed air in an air dryer is called a desiccant. It needs to be changed every now and then to make sure the air dryer is working its best.
Desiccants are things that can take moisture out of the air. Air dryers usually use silica gel and activated alumina as their desiccants, which help remove moisture from the air. The moisture absorber is put in a round box inside the air dryer. Air goes through the box and the absorber takes out the water.
How long a desiccant lasts depends on different things like what kind of desiccant it is, if it's good quality, how the air dryer is used, and how much and how good the compressed air going through it is. Air dryers need new desiccants every 1 to 2 years or when they can't soak up any more moisture.
If you want to know if you need to change the desiccant, you can check how much pressure has been lost on the desiccant layer. When the desiccant takes in water, it becomes full, and the pressure difference over the desiccant bed goes up. When the pressure goes down too much, you need to change the thing that dries out the air.
You can check if you need to change the drying agent by testing how much moisture is in the compressed air after it goes through the dryer. If the air gets too wet after going through the dryer, it means the dryer is not working right and needs a new part called a desiccant.
Remember that how often you need to change the desiccant depends on what you are using it for and the environment it is in. If the air that is squeezed has a lot of dirt and oil in it, the dry substance in the machine that cleans it might get dirty faster and stop working properly sooner. Sometimes, you have to change the drying agent more often or add extra filters to get rid of dirt before putting air through the dryer.
Besides changing the desiccant regularly, it's important to take care of the air dryer often to make sure it works its best. This means making sure the filters are clean, looking at how the valves and pipes are working, and watching to see if the system is running okay. Taking care of your air dryer by keeping it maintained regularly can help it last longer and work properly all the time.
To end, the stuff inside air dryers that sucks up dampness needs changing every 1-2 years or when it can't absorb anymore moisture. The desiccant's life may change depending on how it's being used and the surroundings. You need to check how much air is getting through the desiccant and see if there's too much moisture in the air that comes out of the dryer. This will tell you when to change the desiccant. It's important to take care of the air dryer so it works well and lasts a long time. You should do regular maintenance to keep it in good condition.
