4.2. Mixer Shaft – Direction of Rotation
The direction of rotation for the mixer shaft is clockwise when viewed from above, as
indicated on the mixer nameplate.
Changes to electrical connections to reverse the direction of rotation must be done by
qualified personnel only.
4.3. Air requirements
The air motor requires a clean dry lubricated shop compressed air supply. An Air Line
Filter / Regulator & Lubricator is required in the supply line.
Adjust the air line lubricator to 1 drop of oil per minute. Regulate the line pressure to 7-
bar max.
Noise-air motors are supplied with the standard muffler on the exhaust air.
4.4. Impeller Installation
Folding impellers are normally mounted on the end of the shaft as illustrated, and is
secured in place by two screws.
Dual Impellers
- For viscous materials, Dual Impellers ensure a good top to bottom
turnover in the IBC with the second impeller positioned approximately halfway up the
shaft. Dual impellers can also be used for wetting powders with the upper impeller
positioned approximately 150mm below the liquid surface.
