Description
Wet compressed air is the quiet killer of blasting and painting equipment: it clumps abrasive, plugs metering valves, rusts blast pots from the inside, freezes air tools in winter and puts fisheyes in paint. Super-Dry point-of-use compressed air dryers, water separators and filters fix that at the machine, where it matters, as a supplement to (not a replacement for) a central refrigerated or twin-tower dryer. Kresco distributes the Super-Dry line and fits it to its blast pots, cabinets, blast rooms and spray gun washers; Solvent Recycling Systems supplies it in the US with the equipment or on its own.

D Series Desiccant Point-of-Use Air Dryers (to 300 SCFM)
Three stages in one housing: an inlet polypropylene coalescing element strips oil and solid particles, an activated-alumina desiccant bag absorbs water vapor, and an outlet coalescer polishes the air. A humidity and temperature indicator on the housing shows when to swap the self-contained desiccant cartridge; an automatic timer drain dumps condensate.
- Flows up to 300 SCFM; pressure dew point −40°F; maximum working pressure 150 PSIG; zero air loss
- Heavy-duty powder-coated aluminum casting with stainless V-band clamps for quick cartridge changes; wall brackets included
- Optimized flow path for minimal pressure drop; optimum filter efficiency even at low flows
- 10-year warranty, 25-year life expectancy
- Applications: sandblasting, paint spraying, dust collector pulse air, foam spray, air welders, plasma cutting, air tools, packaging equipment
The D Series is non-regenerative and will not hold a stable dew point for continuous operation; it supplements a central system rather than replacing a twin-tower dryer. Typical installs run compressor → after-cooler → FSD water separator → SAF filter(s) → D Series dryer at the point of use. Model selection by SCFM and port size is on the Super-Dry catalog; tell us your flow and we’ll pick the housing.
ATD Series In-Line Dryers

FSD Series Water Separators (to 515 SCFM)
Heavy-duty housings that remove bulk liquid at any flow, with a zero-air-loss float drain included and an auto-drain option. Maximum inlet 232 PSIG and 176°F.

SAF Series Compressed Air Filters
Three element grades in the same housings: Grade X general purpose (1.0 micron particles, 0.5 ppm oil carry-over, 0.44 psi drop), Grade Y high efficiency / oil-free (0.01 micron, 0.01 ppm, 1.74 psi), Grade Z activated carbon for odor and taste (0.003 ppm oil, 1.31 psi). Removes up to 99% of contaminants.
| Model | Flow at 100 PSIG | Ports (NPT) | Size (A × B × C) | Element | Weight |
|---|---|---|---|---|---|
| SAF-45 | 45 SCFM | 1/2″ | 3.75″ × 8″ × 6.75″ | E-45 (X/Y/Z) | 2 lb |
| SAF-85 | 100 SCFM | 3/4″ | 3.75″ × 10.5″ × 9.5″ | E-85 (X/Y/Z) | 2.2 lb |
| SAF-185 | 180 SCFM | 1″ | 5″ × 12″ × 10.25″ | E-185 (X/Y/Z) | 5 lb |
Larger SAF housings are listed in the catalog; ask us.
TD Series Timer Drains and HGT Humidity Gauge
The TD timer drain combines a solenoid valve, ball-valve strainer and electronic timer to purge condensate from compressors, dryers and receivers automatically: TD-1/4 (110 V, 1/4–1/2″ dual port), TD-1/4 12 VDC and TD-1/4 220 V, each adjustable from 0.5–45 minute intervals and 0.5–10 second discharge, 2 lb. The HGT-1/4 humidity gauge (20–100% RH, 10–160°F) screws into a D Series dryer to show cartridge saturation; install the brass snubber to protect the dial.
Where We Fit It
- Ahead of the air inlet on SBP blast pots and the pot in a blast room
- On the control-air line of PowerBlast and CleanBlast cabinets and their pulse-cleaned dust collectors
- Feeding spray gun washers and paint lines in the booth

Compressed air dryer and water separator FAQs
Desiccant or refrigerated compressed air dryer: what is the difference?
A refrigerated dryer chills air at the compressor to around a 35–40°F dew point and is the usual central plant dryer. A desiccant dryer adsorbs moisture and reaches much lower dew points; Super-Dry D Series reaches −40°F pressure dew point. Point-of-use desiccant dryers catch the moisture that still condenses in long air lines before it reaches a blast pot or paint gun.
Do I need a water separator on my air compressor line?
Yes, ahead of any dryer or fine filter. A water separator removes bulk liquid water and oil so downstream dryers and filters are not overwhelmed. Super-Dry FSD water separators handle up to 515 SCFM with a zero-air-loss float drain.
How do I size a point-of-use air dryer?
Size by the air flow (SCFM) the equipment uses at its operating pressure, plus line size. D Series dryers handle up to 300 SCFM; ATD in-line dryers handle 22–44 SCFM for a single tool, paint gun or pot control circuit. Send us your SCFM, line size and what the air feeds.
Why does compressed air moisture matter for sandblasting and painting?
Water in the air clumps abrasive, plugs metering valves, rusts blast pots, freezes air tools in winter and causes fisheyes and blistering in paint.
