By adjusting the fan rotation speed, the fan produces the required gas flow. Variable speed control can replace the current control mechanism, such as output damper, inlet vanes or slip coupling. Saving electricity often results in a short payback period for the variable speed drive investment.
Pneumatic actuators. ABB pneumatic actuators are suitable for applications that require rotary or linear motion for the positioning of air dampers, fan inlet vanes, louvers, diverters, lever operated ball or butterfly valves, turbine governors, fluid drives and any other similar final control elements.

The special design of the pocket vanes works as a coarse material trap. The oversized coarse particles are carried by the airflow into the classifier where it impacts the angled pocket vanes, loses velocity and falls down to the grit funnel. The turbine rotor then provides an additional barrier that prevents oversized material from passing through.
