{"product_id":"castair-belt-guard-aftercooler-bgac3","title":"Castair Belt Guard Aftercooler BGAC3","description":"\u003cp\u003eThe Castair BGAC3 is a belt guard aftercooler rated at 75 CFM, built for reciprocating compressors in the 20 HP and larger class. If your shop is running a larger two-stage compressor and you are dealing with moisture in your air lines, rusting inside the tank, or water carryover damaging downstream equipment, the BGAC3 is the correctly sized unit for that installation. It installs in the compressor discharge line immediately after the pump head, drops the air temperature, and condenses moisture before it ever reaches the tank.\u003c\/p\u003e\n\n\u003cp\u003eThis is the loose unit configuration — sold standalone without compressor mounting hardware. If you need it pre-configured for direct compressor base mounting, that is the BGAC3M.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the BGAC3 Does and Why It Matters\u003c\/h3\u003e\n\u003cp\u003eA reciprocating compressor discharges air at high temperature — often 250°F or above at the pump head. At that temperature, water stays in vapor form and travels right through the system: into the tank, through the lines, and into your air tools and equipment. An aftercooler cuts that off at the source.\u003c\/p\u003e\n\u003cp\u003eThe BGAC3 routes the hot discharge air through a finned core. Ambient shop airflow — typically from the compressor flywheel or a dedicated fan — passes over that core and drops the air temperature to within 15°F above ambient. At that temperature, water vapor condenses into liquid, drops out of the airstream, and drains away. What reaches your tank and distribution system is cooler and significantly drier air.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature reduction:\u003c\/strong\u003e Cools compressed air to within 15°F above ambient temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture reduction:\u003c\/strong\u003e Removes up to 65% of water content from the compressed air stream\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo cooling water required:\u003c\/strong\u003e Air-to-air design uses ambient shop airflow — no plumbing connections beyond the air inlet and outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank protection:\u003c\/strong\u003e Keeping moisture out of the tank significantly extends tank service life and reduces corrosion risk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDownstream equipment protection:\u003c\/strong\u003e Cooler, drier air means less wear on pneumatic tools, cylinders, valves, and spray equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDesign and Construction\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt guard integration:\u003c\/strong\u003e Designed to mount within the compressor belt guard assembly — keeps the installation compact and protects the cooler core from shop debris\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\" NPT connections:\u003c\/strong\u003e Standard 1\" NPT inlet and outlet — straightforward connection to compressor discharge and tank inlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-pressure rated:\u003c\/strong\u003e Maximum operating pressure of 250 PSIG — handles the output of industrial reciprocating compressors without issue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-temperature rated:\u003c\/strong\u003e Maximum operating temperature of 350°F — engineered for the full discharge temperature range of larger reciprocating pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance spec:\u003c\/strong\u003e All ratings based on 250°F inlet air temperature — tested under real compressor discharge conditions, not ambient\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoose unit:\u003c\/strong\u003e Ships as a standalone unit without compressor-specific mounting hardware — for field installation or replacement applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e BGAC3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCFM Rating:\u003c\/strong\u003e 75 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 24\" L x 20-1\/2\" W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 20 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection:\u003c\/strong\u003e 1\" NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection:\u003c\/strong\u003e 1\" NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure:\u003c\/strong\u003e 250 PSIG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature:\u003c\/strong\u003e 350°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Temperature:\u003c\/strong\u003e Within 15°F of ambient\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture Reduction:\u003c\/strong\u003e Up to 65%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance Basis:\u003c\/strong\u003e 250°F inlet air temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Loose unit (standalone)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompressor Fit:\u003c\/strong\u003e 20 HP and larger reciprocating compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Cast Air (Castair)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAvailable Configurations — BGAC Series Aftercooler Lineup\u003c\/h3\u003e\n\u003cp\u003eCastair makes the BGAC series in four sizes, each matched to a different compressor output range.

If your compressor is in the 15 HP class, the BGAC2 at 50 CFM is the correct fit. If you are running a particularly high-output system — large-frame two-stage units, continuous-duty industrial compressors — and your discharge CFM exceeds 75, the BGAC4 at 100 CFM is the next step up.\u003c\/p\u003e\n\u003cp\u003eDo not undersize the aftercooler relative to the compressor output. An undersized unit cannot cool the full airflow adequately, which means elevated outlet temperatures and reduced moisture separation. Match the aftercooler CFM rating to what the compressor actually produces at operating conditions, not just the nameplate HP.\u003c\/p\u003e\n\u003cp\u003eIf you are unsure whether the BGAC3 fits your specific compressor or if the BGAC4 is a better match, call us.
