- Record the original forced-air mechanism and distinguish it from any installed nextSTEP rotor/stator upgrade. [source]
- For a documented nextSTEP conversion, identify rotor adaptor flange and stator baseplate separately. [source]
- Record the fitted drive sheaves and mechanism-speed record for the documented conversion. [source]
- Record any added froth crowder and radial launders independently of the mixing mechanism. [source]
FLSmidth Dorr-Oliver Flotation Cells (Legacy): Wet-End and Nameplate Identification
Historic OEM examples: DO-10 R, DO-100 R, DO-300 UT, DO-1550 UT, DO-5 RT and DO-200 RT. R/UT model numbers denote active volume in ft³; RT numbers denote m³. Preserve the suffix and original unit.
