Description
The D Series Single Tower Desiccant Air Dryer is expertly designed for point-of-use and intermittent flow applications, offering efficient and reliable moisture removal. The wet compressed air enters through the inlet, where an off-set inlet creates centrifugal separation to trap water droplets. The air then passes around a polypropylene coalescer element, felt pads, and stainless-steel grids, effectively removing solid particulates. As the air flows upward, it passes through a sewed filtration desiccant bag that acts like a sponge, absorbing moisture. Finally, the air flows through a second stage of filtration to eliminate any desiccant dust. This advanced 3-stage system provides thorough separation, filtration, and drying. When the Moisture Gauge indicates saturation, the cartridge can be replaced quickly and mess-free, thanks to the US stainless-steel clamp. The rust-free powder-coated aluminum housing is made in Canada and includes built-in brackets for easy installation.

FAQ
1. How long does the cartridge last?
  Typically, we recommend changing the cartridge at least once or twice a year (or every 2,000 hours) for point-of-use applications with 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 relative humidity exceeds 80%.
3. Can I regenerate the desiccant?
  For optimal performance, we recommend replacing the desiccant with a fresh cartridge. However, you may dry the desiccant by emptying the bag and heating the activated alumina in an oven at 275°F for approximately 4 hours. Let the desiccant cool before refilling the bag and 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, installing a water separator FSD Series upstream of the dryer will help prevent cartridge flooding.
5. Can I oversize my air dryer?
  Yes, oversizing the air dryer will increase the time between maintenance intervals.
