Composition and purpose of the impeller

The design consists of a flat disk, working blades, a ring, and a hub. The blades have a forward-curved shape, due to which they create a turbulent flow for the best mixing of air with fuel and complete combustion of the resulting mixture. The reinforced bushing allows you to securely fix the impeller on the engine shaft and eliminates vibrations during rotation.

In the catalog, we have selected fan blade wheels for burners of various modifications and power. You can buy a fan wheel from us taking into account the direction of air flow, the diameter of the engine shaft and other characteristics of the burner.
