The air leaving the compressor will always be saturated (i.e. 100% relative humidity). This saturated air must be further dried by passing it through a filter containing a moisture removing element such as a dessicant to further drop the dew point to a level compatible with cold water diving. The difference is that if higher moisture content air is being taken in, more water is condensed out during compression. That liquid water is then removed by the seperators which are located before the filters. Safe diving, Dale -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
