The BAU-5 Injector assembly is a two piece design. The main body (or housing) is all BILLET 6061-T6 aluminum. The butterfly and shaft portion is machined from 6061-T6 aluminum plate. Both pieces are polished.
The BAU-5 is available with butterfly diameter options 5.00” and 5.562”.
The 5.00” and 5.562” units can be ordered with a progressive linkage feature that allows one (or two) butterfly to open approximately half way before the other butterflies (or butterfly) start to open. The butterflies can also be set as on, if desired. The design allows for this adjustment at the track.
