The Natgraph combined stencil processing and wash out booths are available in five standard sizes, intended to cater for the majority of print formats.
 
The combined units have an air operated switch for the brightly illuminated acrylic rear panels. These panels assist in the washing out of fine detail stencils and are vital to ensure the complete removal of the stencil image area.
 
A high pressure in-line pump supplies water to a hand held spray unit via a fully adjustable mixer located inside the unit. A hot and cold water supply is required for this system to function correctly; if this is not available an electric instant hot water heater can be supplied as an option.
