The Haldex PUR
est
is a desiccant type dryer that effectively removes moisture, oil and contaminants from the
compressed air system. This reduces the risk of freezing or corrosion of the components in the air system.
When compressor cut-out is reached, dry air is allowed to flow back to regenerate the desiccant bed.
