This is the correct aftercooler for 40–50 HP compressor systems — the class of machine that typically serves busy multi-bay auto repair shops, body shops running two spray booths simultaneously, fleet maintenance yards, and light industrial operations where compressed air runs continuously through the shift. If your compressor is putting out 120–150 CFM and you are dealing with wet air, excessive tank condensate, or dryer performance problems, the AC150 is the direct solution.\u003c\/p\u003e\n\n\u003cp\u003eHot compressed air — typically 250–350°F at the pump discharge — carries a full load of water vapor in suspension. The moment that air cools, the vapor condenses into liquid water. Where that cooling happens determines where the water ends up. Without an aftercooler, the cooling happens in your receiver tank and downstream air piping — which means water ends up everywhere: in your filters, your tools, your spray equipment, and your refrigerated dryer. With the AC150 in place, the cooling and condensation happen in the aftercooler's heat exchanger, right at the source, before the air enters the tank. One drain point. The rest of the system stays dry.\u003c\/p\u003e\n\n\u003ch2\u003eWhy This Equipment Matters Before You Choose Anything Else\u003c\/h2\u003e\n\u003cp\u003eShops invest in refrigerated air dryers to get dry air. The problem: refrigerated dryers are sized and rated for inlet air at or near 70–100°F. When your compressor discharges at 300°F and the tank cools that to 120°F, your dryer is receiving air that is 50°F hotter than its rated inlet condition. It cannot pull moisture out fast enough. The aftercooler fixes that — it brings the air down to within 15°F of ambient before it enters the tank, so the dryer receives air it was designed to handle. Adding an aftercooler to an existing dryer installation often fixes a wet air problem that the dryer alone could not solve.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features of the AC150 Aftercooler\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e150 CFM Capacity:\u003c\/strong\u003e Rated for compressor systems producing up to 150 CFM — covers 40–50 HP two-stage reciprocating and equivalent rotary screw compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250 PSIG Maximum Pressure:\u003c\/strong\u003e Full pressure compatibility with two-stage reciprocating and industrial rotary screw compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e350°F Maximum Inlet Air Temperature:\u003c\/strong\u003e Built to handle the full discharge temperature range of industrial compressor pumps without degraded performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCools to Within 15°F of Ambient:\u003c\/strong\u003e Brings compressed air from 250–350°F pump discharge down to within 15 degrees of your shop air temperature — critical for downstream dryer and filter effectiveness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e65% Total Moisture Removal:\u003c\/strong\u003e Removes approximately 65% of the water vapor load from the compressed air stream at the source, before the receiver tank — every 20-degree temperature drop removes 50% of remaining moisture\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-1\/2 inch NPT Ports:\u003c\/strong\u003e Standard NPT inlet and outlet connections for direct integration into discharge piping\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan-Cooled Heat Exchanger:\u003c\/strong\u003e Electric fan pulls ambient air across the heat exchanger core — no water line required, no water treatment, no freeze risk in the cooling circuit itself\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e115V \/ 1-Phase \/ 60 Hz Power:\u003c\/strong\u003e Standard single-phase power supply for the cooling fan motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloor or Suspended Mounting:\u003c\/strong\u003e Install on the floor alongside the compressor, or suspend overhead to keep the floor clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorizontal or Vertical Air Flow:\u003c\/strong\u003e Air flow orientation is configurable to match your installation layout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 43.5 inches H x 14.75 inches W x 46.5 inches D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 145 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinnesota Manufacturing:\u003c\/strong\u003e Castair builds to industrial-grade standards in Minnesota — these are not import units engineered to a price point\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat is in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCastair AC150 free standing aftercooler unit\u003c\/li\u003e\n\u003cli\u003eFan assembly and motor (pre-installed)\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch NPT inlet and outlet fittings\u003c\/li\u003e\n\u003cli\u003eMounting hardware for floor installation\u003c\/li\u003e\n\u003cli\u003eInstallation documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eOptional accessories available separately: filter with automatic drain, temperature control valve #86816.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eAvailable Configurations — Full Castair Free Standing Aftercooler Lineup\u003c\/h2\u003e\n\u003cp\u003eThe AC150 sits near the top of the Castair free standing aftercooler range.
