Ingersoll Rand OEM 47770053001 Replacement Aftercooler Kit for 32498065 2475N7.5-P

Ingersoll Rand OEM 47770053001 Replacement Aftercooler Kit for 32498065 2475N7.5-P

This aftercooler mounts on the back of the beltguard on Ingersoll Rand’s 2475N7.5-P premium package reciprocating air compressors. The modine style aftercooler takes the hot outgoing air from the high-pressure piston and cools the air before it enters the receiver tank. This process will remove approximately 70% of the moisture from your airlines.

The original part number for this air cooled aftercooler (ACAC) was 32498065. Ingersoll Rand discontinued this cooler and now sells a conversion kit that includes all required items to mount the new aftercooler. The two ACAC coils have similar shape and function, however the manifold connections are now 5/8" npt (#32498149) versus the former 3/4" npt size (#32498065).  

47770053001 aftercooler kit includes:

• 32498149 aftercooler which will mount on the back of the beltguard
• 32174286 safety valve that connects to the aftercooler
• 32188450 discharge tube that connects from the compressor pump to the cooler
• 37143542 1/4" street elbow
• Qty 2 47770364001 - 3/4" x 5/8" inverted flare adapters to connect the cooler to the discharge lines

47770053001 aftercooler is only meant for the 7.5hp version compressor of the 2475 pump manufactured by Ingersoll Rand BEFORE January 2021. The serial number break is CBV739422. If your serial number is before this date, then purchasing this 47770053001 cooler is correct.

Note - If you are running a 5hp 2475N5 air compressor or your 7.5hp 2475N7.5 was manufactured after January of 2021, you are able to purchase the 32498149 aftercooler only. 

This is an OEM kit from Ingersoll Rand compressors.
