D1 - Desiccant Air Dryer

DESCRIPTION

The D Series is a single tower desiccant air dryer designed for point-of-use and intermittent flow applications.   The wet compressed air enters at the inlet, is first separated due to the off-set inlet creating centrifugal separation to trap water droplets, and subsequently passes around a polypropylene coalescer element, felt pads, and stainless-steel grids to remove solid particulates.  The air flows upward through a sewed filtration desiccant bag that acts as a sponge to absorb moisture.  Finally, the air flows again through the second filtration stage to eliminate any desiccant dust.  This 3-stage system efficiently provides separation, filtration, and drying. It is time to replace the cartridge when the Moisture Gauge indicates saturation.  The replacement is fast 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.  A superior alternative to Devilbiss DAD 500, Camair CT30, MP Filenco, Van Air Moisture Block.

FAQ

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. You can estimate the cartridge's life by using our Cartridge Life Calculator.

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.
