If you are running a 5 HP, 7 HP, or 10 HP reciprocating piston compressor and dealing with moisture in your lines, water in your tools, or corrosion in your downstream equipment, this is the component that solves the problem at the source. Air exiting a compressor pump head runs hot — often above 200°F — and that heat carries water vapor. When that vapor cools in your tank and lines, it condenses into liquid water that travels downstream. An aftercooler intercepts that heat immediately after the pump, cools the air to within 15°F of ambient temperature, and drops most of the moisture out before it ever enters the tank. The BGAC1 is sized and configured to do that job for the 5-10 HP compressor range without adding a separate cooling fan, an external mounting structure, or a major plumbing overhaul.\u003c\/p\u003e\n\n\u003ch3\u003eHow the Belt Guard Mount Works\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlywheel Fan Cooling:\u003c\/strong\u003e The BGAC1 mounts to the compressor belt guard and uses the existing flywheel fan airflow to cool the heat exchanger core — no separate fan motor, no electrical connection, no parasitic load on the system\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClean Installation:\u003c\/strong\u003e Because the aftercooler integrates into the belt guard assembly, you avoid the separate mounting brackets and exposed plumbing runs that come with standalone aftercooler installations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePassive Operation:\u003c\/strong\u003e Once installed, the BGAC1 operates automatically any time the compressor runs — there is nothing to switch on or maintain beyond periodic inspection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Mounting Footprint:\u003c\/strong\u003e The 18\" L x 10-1\/2\" W core dimensions fit within the belt guard mounting envelope of compatible Cast Air compressor models — verify fitment with your specific compressor model number before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMoisture Reduction Performance\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCools to Within 15°F of Ambient:\u003c\/strong\u003e Based on 250°F inlet air temperature, the BGAC1 brings discharge air temperature to within 15°F of the ambient air temperature at the installation site\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduces Water Content by Up to 65%:\u003c\/strong\u003e At rated conditions, the BGAC1 removes up to 65% of the water vapor from the compressed air stream before it reaches the tank\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e20°F = 50% Moisture Reduction:\u003c\/strong\u003e Every 20°F drop in air temperature reduces the water content of the air by approximately 50% — the more the aftercooler cools the air, the more moisture drops out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtects Downstream Equipment:\u003c\/strong\u003e Less moisture reaching your filters, dryers, regulators, and tools means longer service intervals, fewer regulator failures, and less internal corrosion in your lines and tanks\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 BGAC1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Air-cooled aftercooler, belt guard mounted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCFM Rating:\u003c\/strong\u003e 35 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Dimensions:\u003c\/strong\u003e 18\" L x 10-1\/2\" W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection:\u003c\/strong\u003e 3\/4\" NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection:\u003c\/strong\u003e 3\/4\" NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 8 lbs\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\u003ePerformance Basis:\u003c\/strong\u003e 250°F inlet air temperature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Drop:\u003c\/strong\u003e Cools to within 15°F of ambient\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMoisture Reduction:\u003c\/strong\u003e Up to 65% at rated conditions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling Method:\u003c\/strong\u003e Air-cooled via compressor flywheel fan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Compressor Size:\u003c\/strong\u003e 5 HP, 7 HP, 10 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $307.23\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAvailable Configurations — BGAC Aftercooler Lineup\u003c\/h3\u003e\n\u003cp\u003eCast Air makes belt guard aftercoolers across four size ranges.
