Modern commercial vehicles use diesel engines, where the working air is compressed by a turbocharger and directed to the engine through a charge air cooler.

In this case, the charge air hoses are a flexible link between the stationary components of the turbocharging system and the moving parts of the engine. The TOPRAN brand Charger Air Hose are exposed to high temperatures, corrosive gases, liquids and significant pressure drops. Low-quality products are not able to withstand such loads for a long time, which, in turn, leads to a significant drop in performance and complete failure of the vehicle.

Principle of the charger air hose work

The modern charger hose acts as an airline, which is designed to directly transfer air from the pumping element to the spray gun. In most cases, a twisted version is used, which is characterized by high efficiency in application. Hoses play an important role - due to their elasticity, they compensate for longitudinal and lateral vibrations of pipelines, radiators and other components, ensuring the tightness of the system.
