Mix head eductor for diluting and dispensing concentrated chemicals such as cleaners and disinfectants

摘要

n eductor apparatus 20 comprises a housing 22 and a fluid inlet port 30 which directs fluid through an air gap 32 to an eductor 42. The eductor 42 is of a one-piece construction. A rib 38 extends from the housing and is located between the air gap and the eductor. The eductor includes a leading 115 and trailing 117 portion, a first inlet port 44 located in the leading portion and a first outlet port 48 located in the trailing portion. A channel 104 communicates with ports 44 and 48. The eductor includes a second inlet port 46 defined in a support arm 98 which extends at an angle from the body of the eductor. A second channel 102 is defined in the support arm and communicates port 46 with the first channel. A second support arm 100 is disposed in a direction opposite to support arm 98. The first channel defines a primary fluid flow path and a secondary fluid flow path is defined between the eductor body and the eductor housing. The rib 38 is positioned relative to the first inlet port 48 in order to permit fluid flow from port 48 both into port 48 and over the exterior surface of the leading portion of the eductor. The apparatus may be used for mixing concentrated chemicals using water from a public water supply and for dispensing the mixture.
