This Lochinvar venturi assembly is a crucial component designed for use in various heating systems. The venturi effect, named after Giovanni Battista Venturi, is a principle in fluid dynamics that allows this assembly to function. It works by reducing pressure and increasing velocity of a fluid passing through a constricted section of pipe, which aids in the efficient mixing of gas and air within the system. This particular Lochinvar venturi assembly is constructed from high-quality materials ensuring durability and longevity. It is designed to be compatible with specific models of Lochinvar heating systems, providing optimal performance and efficiency when installed correctly.
