The Castair RDD80.060 is a refrigerated compressed air dryer from Castair's RDD80 series — the higher-capacity tier of the RDD dryer line. The .060 suffix identifies a specific capacity or configuration variant within the RDD80 series. Like all Castair refrigerated dryers, the RDD80.060 maintains a 37°F pressure dew point using R134a or R407c refrigerant and a stainless steel dual-function heat exchanger to remove water vapor from compressed air before it reaches tools, equipment, and air distribution systems.
The RDD80 series is positioned above the RDD40 and RDD50 dryers in Castair's lineup — it is built for higher compressed air flow requirements where the RDD40 series would be undersized. Full specifications including CFM capacity, electrical requirements, connection sizes, and physical dimensions are available by contacting us directly at 866-217-0063.
Key Features — Castair RDD80 Series
- Pressure dew point: 37°F — standard for automotive, industrial, and manufacturing compressed air systems
- Refrigerant: R134a or R407c (environmentally compliant, not R22)
- Heat exchanger: Stainless steel, dual-function single-body — incoming hot air pre-cooled by outgoing cold air for improved efficiency
- Automatic demand drain: Activates only when condensate is present — no timer-based air losses
- Dew point indicator: Simple visual — no computer controls, no programming, no proprietary boards to source
- Quick-connect refrigerant port: Field recharge without full disassembly
- Maximum inlet pressure: 232 PSIG
- Certifications: UL listed
What's in the Box
- Castair RDD80.060 refrigerated compressed air dryer unit

A properly sized pre-filter upstream of the dryer is required for warranty coverage. Contact us for pre-filter sizing guidance for your specific installation and compressor output.
Castair Refrigerated Dryer Series Comparison
Castair offers two distinct refrigerated dryer product lines:
- RD Series (RD25-6K through RD161-37K): Single-stage units from 25 CFM to 161 CFM. All run on 115V/1-phase/60Hz. Published specifications available. These are the standard shop and commercial dryers.
- RDD Series (RDD40, RDD50, RDD80): Alternative or extended lineup — RDD40, RDD50, and RDD80 variants. Full specs require direct confirmation. Call for the right unit for your flow requirement.
When Does a Shop Need a Dryer at This Capacity Level
- Compressor systems producing higher CFM output where the RDD40 and RDD50 dryers are undersized
- Multi-compressor installations where a single downstream dryer handles combined output
- Large body shops, paint operations, or manufacturing with continuous high-flow air demand
- Any application where moisture breakthrough during peak demand is a documented problem with a smaller dryer
Capacity note: All Castair refrigerated dryer ratings are based on 100°F inlet air temperature, 100°F ambient, and 100 PSI. At 150°F inlet air, capacity drops to 55% of rated. An aftercooler between the compressor and dryer inlet is recommended in high-temperature environments to maintain full rated capacity.
