3.2.4 Plenum Chamber and Interchangeable Inserts
The plenum chamber provides a surface for the fabric to press against when raised during a clean-
ing sweep, a solvent spray bar to "wet" the fabric with solvent and vacuum (via machine mounted
vacuum filtration unit [see 3.2.6 "Vacuum Filtration" [}18]) to aid with excess paste removal.
The plenum chamber has a removable insert section, with a choice of three differing tops (detailed
later in this section). All inserts are fitted with a connector for the solvent tubing.
The plenum chamber and associated inserts are available in the following widths:
Plenum Insert 300mm 400mm 460mm 515mm 620mm

3.2.4.1 Hard Top Insert
The hard top insert works well for standard cleaning or stencils/paste mediums that require high
vacuum to aid excess paste removal.
3.2.4.2 Poly Blade Insert
The poly blade insert works well with stencils with irregular undersides (worn stencils, coined sten-
cils, stepped stencils etc).
3.2.4.3 Duo Insert
The duo insert is capable of performing a WET and VAC clean in one sweep, an option which uses
less fabric roll and has less of an impact on machine throughput.
3.2.5 Solvent Pump and Supply
The solvent pump mounted on the right-hand USC cleaner support bracket, supplies solvent to the
plenum chamber mounted solvent spray bar which can then be applied to the fabric roll. The
solvent tubing from the pump is fitted with a quick release connector, which makes the removal of
the plenum chamber for maintenance etc much simpler.
The pump provides solvent from the external solvent tank mounted on the rear or either side of the
machine. The external solvent tank is capable of accommodating a 5 litre container of solvent. A
load cell in the base of the external solvent tank enables the software to calculate the percentage
level of solvent within the container.

3.2.6 Vacuum Filtration
The vacuum filtration unit extracts solvent fumes and draws excess print material onto the fabric.
The machine mounted vacuum filtration unit connects to the USC plenum chamber via a vacuum
tube assembly. Vacuum filtration is optional and may be one of the following types:
●
VF35 Vacuum Filtration Unit
●
VF25 Vacuum Filtration Unit
●
VF10 Venturi Vacuum Filtration Unit
NOTE
For information on the removal and replacement of the filters, refer to the Machine Preventive
Maintenance manual.
