I recommend that anyone concerned about air quality in their studio
check out the Quatro products (out of Canada) available from Grobet
&/or Otto Frei -(usual disclaimers, no financial connection to
either company) - I have recently upgraded my studio and have
switched to their stand alone polishing unit, Solderpure system for
soldering areas and pickle areas, as well as the small unit for my
bench. Jet Stream Compact Dust Collector.
All units are compact, self contained, and portable - clean air is
returned to the working environment, CFM is appropriate for each
work station, motors are relatively quiet - no duct work to install.
Yes they are more expensive than a window fan or a kitchen hood -
but they are less expensive than installing ductwork - plus they do
not just remove the "bad" air, they clean it. (& they are expandable
for multiple work stations)
Both Quatro and John Frei will answer any questions about the equip.
