How much engagement should I use on my brush?

The engagement of the brush should be to a fixed interference point - about 1/32 to 1/16 of an inch, which can be adjusted to allow for wear. Typically, air cylinders are used to engage/disengage the brushes. However, adjusting the engagement by controlling the pressure is not recommended. Excess pressure will produce over-engagement with premature wear and lost power.

 How long will my brush last?

Some of Jenkins' brushes are still in use after 20 years on the job. This is far beyond a normal useful life but it gives you an idea of the durability of a properly maintained brush.
It's always a good idea to have spares for cleaning.

 How do I inspect a brush?

Check the brush for accumulation of material - the cleaner the brush is, the more effective it is. Watch out for filament wear, especially if the wear is uneven. If it is, adjustments to the machinery are required.

 How often should brushes be inspected?

For most applications quarterly is often enough, but inspections should be geared to your regular maintenance schedules.

 What's the best rotation speed for a brush?

The minimum speed for your application will produce the best results and the least wear. A good rule of thumb is 2-3 times the speed opposite of travel, but your specific application can have an impact on the results.
