Why do I need to purchase a VSD (variable speed drive) as part of my dust extraction system?
VSD’s (variable speed drives) provide a major cost saving component with your dust extraction system purchase as they allow you to automatically set the suction levels on all machines. This adjusts the speed of the extraction fan according to the machines in operation. For example, if the fan is operating at 80% capacity, this translates to a reduction in power bills of 50%. It is the “green” option, which will also result in a reduction in noise levels.
