Castair Refrigerated Dryer Replacement Filter Element — .060 Micron (RD.060-S)
The Castair RD.060-S is a .060 micron replacement filter element for Castair refrigerated dryer pre-filter assemblies, S-series housing. The .060 micron rating is the coarsest in the Castair RD replacement element series, making it appropriate as a first-stage pre-filter in a two-stage filtration arrangement before the dryer, or for applications where the primary concern is larger particulate and bulk water rather than fine oil mist removal.
In most shop installations, you would run the RD.060-S first-stage upstream of a finer RD.016-S or RD.030-S element. The .060 micron stage removes larger particles and coalesces larger water droplets before they reach the fine-micron stage, extending the service life of the more expensive finer element. In single-filter setups, the RD.030-S is typically more appropriate than the RD.060-S unless your compressed air stream is relatively clean and you are mainly managing bulk water at the pre-dryer stage.
Specific housing compatibility data for the RD.060-S were not published on castair.net at time of writing. Contact 866-217-0063 with your housing model and installation to confirm this is the correct replacement element.

RD Replacement Element Comparison
- RD.016-S: .016 micron — finest filtration, highest oil removal efficiency, shortest element life in contaminated systems
- RD.030-S: .030 micron — general-purpose pre-dryer coalescing for most shop applications
- RD.060-S (this part): .060 micron — coarser first-stage pre-filter, use in conjunction with a finer element or where bulk water is the primary concern
Two-Stage Pre-Filtration Setup
For the best balance of dryer protection and filter element service life, Castair recommends running a pre-filter arrangement before the refrigerated dryer. A two-stage approach — .060 micron first, then .016 or .030 micron — captures large contaminants in the first stage (cheap element, easy replacement) and removes fine oil mist in the second stage (more effective at its job because it is not overloaded with bulk contamination). The dryer then sees clean, dry air entering the heat exchanger.
When to Replace
- Replace at differential pressure indicator — coarser elements may load faster in high-particulate environments because they catch larger debris
- In clean air applications, .060 micron elements may last longer than finer elements before needing replacement
