YANMAR N21 / N18 – Air Cooler & After Cooler
Component Overview
YANMAR is a globally trusted name in the marine industry, backed by a century-long engine manufacturing tradition, Japanese quality standards, and a wide range of engines for marine propulsion and auxiliary applications.
The air cooler and after cooler are essential components that reduce the temperature of compressed air before it enters the combustion chamber. This improves air density, enhances combustion efficiency, and ensures optimal engine performance and reliability.
At AL-TECH INTERNATIONAL, we maintain a large stock of air coolers and after coolers for YANMAR N21 and N18 engine series used in marine and power plant applications. We also supply a comprehensive range of engine components including crankshafts, engine blocks, camshafts, liners, cylinder covers, pistons, connecting rods, fuel pumps, water pumps, lubricating oil pumps, fuel feed pumps, governors, and other essential parts.
