Renacer Air Stone 10cm 4"

 An air stone for an aquarium comprising an air-receiving element, a baseplate connect to the air-receiving element and a water insoluble annular-shaped fiber mat. The fiber mat contains a weight therein in concentric relation thereto and the mat is disposed intermediate the air-receiving element of the baseplate. The air stone is adapted to supply a uniform stream of air bubbles to the water contained in the aquarium when connected to an air supply.

The air-receiving element further comprises an air inlet tube, an air inlet aperture located therein, a shoulder portion located at the base of the air inlet tube and a cap portion disposed at the base of the shoulder portion. The air inlet tube, the shoulder portion and the cap portion are integrally connected. The air inlet tube flares outwardly toward the base juncture with the shoulder portion so that when an air supply tube from the air supply is connected to the air inlet tube the air supply tube is held in airtight relationship therewith. The air-receiving element has a cloverleaf-shaped aperture disposed in the cap portion and extending into the shoulder portion from the face of the cap portion.
