How it works

Exact regeneration air, right when it’s needed.

Instead of purging around the clock, the Select Purge Dryer runs its regeneration cycles alongside your compressor. When the compressor stops, so does the purge, which keeps your air system from draining overnight.

It’s ideal for new systems, retrofitting existing dryers, and remote locations such as paint booths.
