With an integrated aftercooler, the
Blast Pak first cools hot and wet air discharged from the
compressor. Cooling forces a substantial quantity of entrained
moisture to condense. But even after exiting the aftercooler, the
air is still saturated with vapor (100% relative humidity). Next
the compressed air passes through the drying vessel, which contains
a specially formulated Van Air desiccant called Dry-O-Lite. This
desiccant cuts the humidity of the air roughly in half. Finally,
air flows through an after-filter to trap any fine particulate
matter suspended in the airflow.
The blasting contractor is left with
cool, clean and dry compressed air for superior blasting quality
and zero downtime.
Blasting contractors: remember that
an aftercooler and moisture separator alone do not prevent
condensation from occurring downstream. To lower the humidity of
blasting air, and prevent condensation from occurring on the
blasted surface, a dryer must be used. Dry air is the key to
superior surface preparation.
