1. How long does the cartridge last?
Typically we recommend changing the cartridge at least once to twice every year (or every 2,000 hrs) when used for point-of-use applications with an intermittent flow.
2. When do I know when to change the cartridge?
Use our moisture indicator HGT-1/4 and replace the cartridge when the R.H. exceeds 80%.
3. Can I regenerate the desiccant?
We highly recommend replacing the desiccant with a fresh cartridge for optimal performance. However, you may dry the desiccant by emptying the bag and leaving the activated alumina in an oven at 275 F for 4 hours (approximately). Let the desiccant cool down before refilling the bag. Use a commercial stapler to close the bag.
4. How can I extend the life of the cartridge?
We recommend draining the tower daily by opening the ball valve or using our automatic timer drain TD-1/4. When there are bulk liquids in the compressed air, a water separator FSD Series installed upstream of the dryer will knock water and prevent the flooding of the cartridge.
5. Can I oversize my air dryer?
Yes, oversizing the air dryer will increase the time in between maintenance.
