{"product_id":"castair-belt-guard-aftercooler-bgac2-kit","title":"Castair Belt Guard Aftercooler BGAC2 Kit","description":"\u003cp\u003eThe Castair BGAC2K is the kit version of the BGAC2 belt guard aftercooler — it combines the 50 CFM aftercooler core with the mounting hardware and brackets needed to install it on the belt guard of a 15 HP reciprocating air compressor. If you want to do the installation yourself and need everything in one package, this is the right order. You get the core and the hardware; you do the mounting.\u003c\/p\u003e\n\n\u003cp\u003eThe difference between the BGAC2, BGAC2K, and BGAC2M comes down to how much work is done for you before it ships. The BGAC2 is the bare core — no mounting hardware. The BGAC2K is the core plus the mounting hardware. The BGAC2M is the core already assembled to the mounting panel, ready to bolt on. If you have a standard 15 HP belt-drive reciprocating compressor and a basic set of hand tools, the BGAC2K gives you everything you need without paying for factory pre-assembly.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Is Included in the BGAC2K Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAftercooler core:\u003c\/strong\u003e 50 CFM belt guard aftercooler, 18 in L x 14-1\/4 in W, 1 in NPT inlet and outlet connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting hardware:\u003c\/strong\u003e Brackets and fasteners for installation on a standard compressor belt guard panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEverything needed for a complete belt guard aftercooler installation\u003c\/strong\u003e — minus the plumbing fittings and condensate drain, which depend on your specific site layout\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCore Performance Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCFM Rating:\u003c\/strong\u003e 50 CFM — matched to 15 HP reciprocating compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Inlet Air Temperature:\u003c\/strong\u003e 250°F\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\u003eCooling Performance:\u003c\/strong\u003e Cools compressor discharge air to within 15°F above ambient temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture Reduction:\u003c\/strong\u003e Up to 65% reduction in water content\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture physics:\u003c\/strong\u003e Approximately 50% of water content drops out for every 20°F reduction in air temperature.

The fan is driven by the compressor itself — no external blower needed. As the fan pulls air across the core, it removes heat from the compressed air passing through the internal passages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge-point installation:\u003c\/strong\u003e The BGAC2K installs between the compressor cylinder head discharge port and the receiver tank inlet. Compressed air at 200–350°F enters the aftercooler and exits at close to ambient temperature before it ever reaches the tank.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondensation before the tank:\u003c\/strong\u003e Cooling the air before it enters the tank causes moisture to condense at the aftercooler outlet rather than inside the tank and downstream lines. This is where you want the condensation to happen — at a controlled drain point, not scattered throughout your distribution system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePair with a moisture separator:\u003c\/strong\u003e For best results, install a moisture separator\/trap at the aftercooler outlet. The separator catches the liquid that condenses out and channels it to a drain. An automatic float-type drain valve keeps the system hands-free.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho Should Order the BGAC2K vs. BGAC2 or BGAC2M\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder BGAC2K if:\u003c\/strong\u003e You have a standard 15 HP belt-drive reciprocating compressor and you want to do the installation yourself.
