Abstract
Disclosed is an eductor for mixing water with a foamable concentrated surfactant. A venturi aspirates the surfactant into a water stream. The diluted surfactant is then delivered into a bottle, pail, bucket, or other container, e.g. for use in custodial applications. A baffle chamber and spider baffle are provided downstream of the venturi in the eductor to reduce foaming. The baffle can be cross shaped, with a large central region.
