The Importance of Air Filters for R.C. Cars (Part 1)

An air filter is an important component of a Nitro engine. The engine needs a mixture of clean and unrestricted air and fuel to provide power for the RC vehicle. Since nitro engine requires clean an unrestricted flow of air for smooth running and more power the air filter is the first line of defense or the first important component that makes sure that the engine runs to its optimum. All RC vehicles make use of this device to derive the optimum power level for their engines.

The air filter keeps away the dirt, contaminants and other debris getting into the engine. If these foreign particles enter the engine they might seriously harm the engine capabilities and definitely would tune the performance of the vehicle.

There are three types of air filters. Most common of them is Foam air filters which use foam filter oil. These filter oils should be without solvents as filters tend to disintegrate if you use filters oils with solvents in it. Single stage foam filters contain single core. This core is used to filter dust, dirt and similar contaminants. Dual stage foam filters have two levels of protection to prevent contaminants. The second core is thicker and blocks smaller particles.

Cotton air filters are the most common replacements to foam air filters. They have less air resistance as compared to foam ones. Care is required in case of cotton air filters so as to not to over-saturate them. It is important for air filter to dry overnight.
