INSTALLATION TIPS:

Connect the California Air Tools RD-91503 98% Refrigerated air dryer to the output of the Air Compressor, then connect to final tooling/application.
If Air Compressor does not have an output filter (5 um filtering minimum) to prevent ingestion of contaminents into the RD-91502 dryer, then it is suggested to install a filter (or regulator with filter) between air compressor and RD-91503 Dryer.
To help reduce observed/temporary air pressure losses at output of RD-91503 Dryer, it is suggested to add an Auxiliary Air Tank between Air Compressor and RD-91503 Dryer (i.e. provides stable air buffering).

ISO 8573 Class 4 Air Drying System
Limitations: Not suitable for applications requiring dry air with extremely low dew points (i.e. ISO 8573 2.3.1 class, PDP -29F to -50F), then instead a desiccant-based air dryer system WILL be required. If ISO 8573 Class 2 compliant clean/dry air is required, California Air Tools offers many air compressor models which achieve a PDP average of -40F (-40℃) -- CLICK HERE --
