The purge air requirement for a heatless vacuum assisted dryer is reduced from around 20% to 3% of a standard heatless dryer.

Energy reductions from reducing the purge air offsets the energy required to operate the vacuum pump, and provides significant energy savings overall.

CDAS/OFAS/FBP LE heatless vacuum assisted dryers operate almost identically to a standard heatless dryer, however their design includes two additional components, a vacuum valve and a vacuum pump.
