Regulators

If the incoming pressure is lower than the set pressure on the regulator, the downstream pressure after the regulator will also drop.

Regulators cannot increase the incoming pressure. The filter delivers the compressed air in a saturated condition.

Always filter the compressed air just before the regulator. Never filter after a regulator.

If the regulator reduces the saturated air from the filter, to a lower pressure, the air will be dry at that lower pressure and temperature.

This will result in the Dew-point being lower at this compressed air temperature and reduced line pressure.

Always reduce the compressed air pressure as close as possible to your point of use.

This will give the compressed air time to cool down in the air line and your filter will be more efficient.
