They may look like flashes of light, quickly here then gone, but sparks are actually bits of very hot metal.
Our screen-and-mesh spark reducer, shown fitted into the capture hood of a flexible extraction arm, can be cleaned with pressurized air.
One reason we know this is the work of early researcher Robert Hooke. In this case, early means 17th century.
(More info about Hooke at the end of this post.)
Spark reducers can trap or break up the tiny metal bits, causing them to cool.
When cool, the resulting particles can be treated like any other form of industrial by-product — a target of good housekeeping practices.
We offer spark reducers for light grinding applications
Spark reducers are available for our Model 500/550 Series, Model 400/450 Series, and for the Model 300 Roundaire. They are frequently purchased for light grinding applications.
Check the table below to match extraction arms to model.
The reducers’ combination of screen and mesh effectively reduces sparks.
The spark reducers fit snugly into the capture hoods, but they can be removed for cleaning with mild detergent.
Our spark reducers can also be cleaned with pressurized air while they remain in the hoods.

Robert Hooke
Unfortunately for Robert Hooke and those of us who might like to know him better, no portrait of him has been uncovered; hence, the varied interpretations of his appearance.
There is gossip, however. Read about Isaac Newton’s possible role in The Royal Society’s blog Hooke, Newton and the ‘missing’ portrait
