Integrated Aftercooler Air-cooled or water-cooled · approach 15-25°F over ambient
The single highest-leverage knockout.Standard on every modern packaged rotary screw and most packaged recip compressors. Retrofit answer for any older install where the customer is complaining about wet tools, short dryer life, or water at every drain point.
Inside the compressor envelopeAlmost always specified and warranted as part of the compressor itself, not as a separate quote line. Performance degrades sharply in hot compressor rooms (above 100°F ambient) — fouled fins and lost cooling airflow are the most common failure modes.

Water Separator Cyclonic bulk-liquid catch · no media to replace
The dryer's first line of defense.Humid-climate plant air, high-duty-cycle systems, any install where the dryer is sized close to capacity. The single highest-ROI retrofit for any customer whose refrigerated dryer trips on saturated outlet in summer.
Liquid only, not vaporRemoves free liquid water by centrifugal force — doesn't touch water vapor (that's the dryer's job) or oil aerosol (that's coalescing). The float drain is the wear item; failed drains overflow and dump bulk water downstream into the dryer.

Reading the brand bench column — the bar shows how many of SPC's tier slots (Industry Leader · Emerging · Economical · adjacent) carry an option at that product type. A deep bench means a price-driven and a spec-driven option both close cleanly; a narrow bench means the available brands map closely to the technical requirements and the comparison stops being a tier choice.
