Adjustable Air Diffuser
The Eheim diffuser is mounted at the end of the outlet hose close to the surface of the water and is fixed on the tank wall to create an injection angle which is as flat as possible. Simultaneously this effectuates an excellent movement of water. The air hose of the diffuser is led to a place outside the aquarium. The quantity of sucked air can be dosed with the aid of the enclosed pressure adjusting clamp as necessary. The diffuser mixes the supplied air flow with return water which is injected under the surface of the water by the pressure of the filter pump.
