ACS BGAC Belt Guard Aftercooler, Copper Coil, 20 to 100 CFM
A belt guard aftercooler is the cheapest way to turn an existing reciprocating compressor into a machine that stores dry air. The coil bolts to the belt guard, the flywheel already moving air through the guard becomes the cooling fan, and the discharge line runs through the coil on its way to the tank. No extra motor, no extra starter, no floor space. The ACS BGAC series uses a copper coil and is rated to 300 PSI.

Sizing
Pick the model by the compressor horsepower it is listed against, then sanity check the CFM against what your pump actually delivers. The ACP price sheet describes the BGAC-25 as covering 15 to 25 HP, while the catalog table lists it at 25 HP, so a 15 or 20 HP machine is also within range for that size. Confirm the belt guard opening will take the listed coil dimensions before ordering.
Why it matters
Air leaves a two-stage pump hot, and hot air holds water. Send it straight to the receiver and the moisture condenses in the tank and in the distribution piping downstream. Cool it first and most of that water drops out at the tank drain, where it belongs. The result is less rust in the receiver, less water at the tool, and a refrigerated dryer downstream that is no longer fighting a high inlet temperature.
Typical applications
Upgrading existing single-stage and two-stage reciprocating air compressors in shops, fleet bays, farms and light industrial plants, and any installation where an aftercooler is wanted without adding a separate fan-cooled unit.
The ACS BGAC belt guard copper coil aftercooler is available from AirComParts in 20, 35, 75 and 100 CFM sizes for 5 through 30 HP reciprocating compressors, rated to 300 PSI.
