It offers a 90-degree air inlet to provide low overhead clearance, and is available with several air horn and throttle valve options. This unit is available for propane, natural gas and digester gas applications. It has been successfully used for other hydrocarbon-based vapor fuels as low as 500 BTU.

The Model 200 is also available for Feedback applications with the “FB” designation. These FB mixers are also available in tamper resistant configuration, indicated by the suffix “-TR” on the part number. It is also possible to convert standard units to a tamper resistant configuration through the use of a retrofit kit (check the Optional Equipment section for more information)
