Turbulent Air 

The VacClean pulls air in between the face plate of the VacClean and the web material requiring 
cleaning. This creates a turbulence that loosens the contamination on the web and allows it to be 
vacuumed off the web.  

Installation  

The installation is covered previously in the beginning of the manual in the installation pages. 

VacClean specific Installation 

The general VacClean installation is covered at the start of the manual, however important areas to 
check when installing are: 

Face Plate Level

Brush height

Multi-web size fingers

Bars

All components of the VacClean are set before shipping but rough handling can cause damage and 
movement of some components, these should be visually checked to ensure correct cleaning of the 
web. 

Inspecting face plate level 

The face plate level can be easily visually checked that it has not come loose or “popped up”. The face 
plate mounts on the VacClean through tensioning screws which can be released if the face plate needs 
to be levelled. The VacClean’s use of vacuum pressure means there can be a large tolerance of 2mm
