Do you know the difference between your equipment’s two main air filters? While both are crucial, they protect entirely different systems. The engine air filter acts as the lungs of your machine, protecting the engine from damaging dirt and debris to ensure peak performance. The cabin air filter is the guardian of your health, purifying the air you breathe inside the cab. This guide explains everything you need to know—from their distinct functions and locations to the critical signs that it’s time for a replacement.

An air compressor aftercooler is a device that cools the hot, compressed air coming from a compressor to reduce its temperature and moisture. The air compressor is the heart of the pneumatic tool system. The air coming out of the compressor is very hot and contains a lot of water vapor. High heat and harmful moisture usually cause silent damage to your equipment. Aftercoolers are the solution to these problems for your equipment.

The water pump and thermostat work together in the cooling system to ensure that the equipment has enough coolant circulating so that the engine does not easily exceed the maximum temperature it can withstand, 220 degrees Fahrenheit. They work together to maintain the good operation of the equipment cooling system, but sometimes, when cooling system problems occur, it is difficult to distinguish which one of them has a problem. Therefore, through this article, you will learn how to clearly distinguish which one of them fault when a problem comes, how they work together, etc., to help you make a quick judgment and replace the broken parts in time.

Ever look under the hood and wonder why there are two “radiators”? You’re not alone. While they look alike, they do totally different jobs.
