I recently purchased the Quattro free standing buffing unit with the
Plexi- box enclosures - love it - they have great technology - their
filtering system cleans the air before it returns it to the
environment. Wish I had bought it yrs ago - great not to wear a
respirator any more.
It is also nice to not have a fine film of rouge drifting around the
studio - never really saw it - but whenever I wiped down a surface
in my studio - there was rouge on the damp rag - even though my
previous polishing unit had a filtering exhaust.
About 12 yrs ago - actually had a cabinet maker build similar plexi
cabinets for the classroom that I teach in - but due to the
technology at the time - it involves a VERY noisy wall mounted motor
and extensive HVAC duct work.
The Quattro system is MUCH more quiet and does not require duct work
to exhaust the air filled with particulates. They claim it is more
efficient at trapping metal that is removed during the polishing
processes - so perhaps in a few yrs., in addition to the benefits of
better air quality in my studio, my refining returns will offset the
Usual disclaimers- I am in no way (other than being a customer)
