FEATURES
The 3 cu ft cabinet is lit by a low voltage (12 volt) fluorescent tube. A transformer
is provided which should be plugged directly into the mains supply. The attached
cable is then plugged into the switchbox, mountred on the left side of the cabinet.
The switchbox contains the ON/OFF rocker switch.
We strongly recommend that this unit be used with a vacuum extraction device.
Air is extracted via a double filtration system from the facility at the right hand
side of the cabinet.
Please note that when vacuum extraction is used, air will be drawn into the cabinet
through the hole on the back panel of the unit. The hole is covered on the outside
with a filter plate, and housed within the plate is a foam filter, which must always
be in place. This is to prevent grit from being blown out, if/when the vacuum
extraction is NOT used.
The lid is provided with a double clear plastic window, the inner of which may be
renewed quickly and easily if it should become damaged by the sand blasting
action.
A variety of abrasive nozzles is supplied with the unit to produce a useful range of
power and grit densities to satisfy all requirements. The cabinet is designed for use
with dry abrasives ONLY. We recommend Aluminium Oxide (for cleaning steel)
and Glass Beads (for cleaning Aluminium).
It is necessary to provide a clean, dry air supply, capable of delivering a minimum
of 10 cuft/min at 100 lbf/in
