ACS BGC Belt Guard Aftercooler, Aluminum Coil, 18 to 125 CFM
The BGC is the aluminum-coil, high-efficiency version of the ACS belt guard aftercooler. It mounts on the compressor belt guard and uses the flywheel's own airflow to cool discharge air on the way to the receiver, so an existing reciprocating compressor starts storing cooler, drier air without a separate fan unit, motor or starter. Five sizes cover 5 through 30 HP machines.

BGC or BGAC
Both mount the same way. The BGC uses an aluminum coil and is the high-efficiency option, rated to 250 PSI and 300 F. The copper-coil BGAC is rated higher, to 300 PSI and 350 F. If the machine runs at 175 PSI or below, the BGC is the one to take; if it is a high-pressure package or runs hot, go to the BGAC.
Why it matters
Discharge air from a reciprocating pump is hot, and hot air carries water into the tank and the distribution piping. Cooling it first condenses the moisture where the tank drain can get rid of it, which means less rust in the receiver, less water at the tool, and a lighter load on any refrigerated dryer downstream.
Typical applications
Retrofitting single-stage and two-stage reciprocating air compressors in machine and fabrication shops, fleet maintenance, agriculture and light industrial plants.
The ACS BGC belt guard aluminum coil aftercooler is stocked by AirComParts in 18, 35, 50, 100 and 125 CFM sizes for 5 through 30 HP reciprocating compressors, rated to 250 PSI.
