Personnel De-duster Unit
Gets an Upgrade
ACI reported that its JetBlack blower-pow-
ered personnel de-dusting unit has been
upgraded. The new unit is more compact yet
has a greater air output without any increase
in energy consumption, and incorporates
reconfiguration of the previous model's inter-
nals, resulting in enhanced air flow to give
10% greater output (2.75 psig) with a reduc-
tion in overall size. The new model, accord-
ing to the supplier, is safe and economical
to run, because it delivers a high volume of
air at low pressure it can be used even
against exposed skin—which can be danger-
ous with high-pressure compressed air. The
standard hose length on the wall-mounted
unit is 142 cm (56 in.), with noise levels
below 78 db(A). A spare filter is included
with each new unit, and filter access is now
easier. The JetBlack outlet nozzle can be fit-
ted with an optional chip guard.
