The aspirator is utilized to introduce air, oxygen, or other gases into a liquid. The advantages of the present design include the ability to inject approximately 30% more air than a conventional current design at 50% of the rotational speed. This reduces the power requirements. Additionally, the 45 degree angle of the aspirator tubes helps to shed debris that might otherwise collect on the aspirator. The aspirator design includes a fin along the aspirator tube, which is formed at a 45 degree angle relative to the aspirator shaft. Superior mixing is provided by the larger profile of the aspirator. The fins along the bottom of the aspirator tubes help to create larger voids in the liquid. This increases the aspirator's capacity to inject air, while minimizing the material requirements of the part.
