FS-Curtis RNB800 Non-Cycling Refrigerated Dryer 800 SCFM #FRNB00800-4XA5XX

FS-Curtis RNB800 — 800 SCFM Refrigerated Air Dryer

A facility running a very large compressor or multiple units into one distribution system needs 3-inch flanged connections and industrial-grade throughput to match — the RNB800 is sized for exactly that kind of high-volume infrastructure.

That's what the FS-Curtis RNB800 solves — a 800 SCFM non-cycling refrigerated dryer, a practical fit for this air volume — enough capacity to matter, without the cost of an oversized unit. It's also available with a factory-matched Filter Package (prefilter CF7-54-24-G + afterfilter CF5-54-24-G) as an add-on option, which means the install crew opens one box with the dryer and its matched filtration inside, not three separate shipments.

Who the RNB800 Is Built For

• ✅ An industrial facility or large commercial shop running a high-output rotary screw compressor that needs matched, continuous-duty drying capacity
• ✅ An operation with a centralized compressed air system feeding multiple work areas, production lines, or bays from one header
• ✅ A facility that needs dependable, round-the-clock dew point control at high SCFM without the pressure drop that undersized filtration or dryers introduce
• ✅ A plant manager replacing an aging industrial dryer who needs the new unit to match or exceed the old one's throughput without a costly re-pipe of existing 2-inch/3-inch/4-inch flanged connections
• ✅ An operation where compressed air system downtime for dryer service is expensive, making reliability and manufacturer-backed 2-year coverage a real purchasing factor, not an afterthought

What the RNB800 Is NOT Built For

• ❌ Small or mid-size shops — this tier is sized for industrial-volume air systems and is oversized, and overpriced, for a single-bay or light commercial operation
• ❌ Facilities without existing 3-phase power infrastructure or the floor space and flanged/NPT piping this unit's footprint and connections require

What Makes the RNB800 Different

Heat Exchanger

The RNB800 uses a stainless steel brazed plate heat exchanger, engineered for reliable, consistent dew point control at 800 SCFM without fouling or excess pressure drop.

Condensate Drain

Timed electric drain removes collected moisture automatically — the drain cycles on a preset interval around the clock, independent of who's on the floor.

Refrigerant & Air Quality

Uses R513A refrigerant, a low global-warming-potential option, and delivers ISO 8573-1:2010 Class 4–5 pressure dew point — dry, reliable air for general shop and industrial use.

Optional Filter Package

Choose the “Includes Filter Package” option to add a factory-matched prefilter (CF7-54-24-G) and afterfilter (CF5-54-24-G), sized to this dryer's flow rate and ready to plumb — one less step for your install crew.
