Vacuum Roll Internal Cleaning Device
A dedicated cleaning device with self-cleaning nozzles that washes the vacuum roll from the inside out — removing contaminants from the drilled holes and inner shell wall, keeping contamination out of the roll and extending roll service life.
Product Overview
Over long operating periods, fibres, fillers and scale gradually build up in the drilled holes and on the inner wall of a vacuum roll shell. Once contaminants enter the roll interior they plug the holes, distort the vacuum profile and accelerate shell corrosion and fatigue.
The vacuum roll internal cleaning device uses self-cleaning nozzles and washes the roll from the inside out — high-pressure water passes through the holes from inside the roll, flushing contaminants off the holes and the inner shell wall completely, while preventing debris from entering the roll interior during cleaning. The cleaning is completed within a normal maintenance window, keeping the vacuum level and dewatering performance at their design values and extending the service life of the roll.
Technical Highlights
System Features
The nozzles clean themselves during operation — resistant to plugging, with stable jet quality over long runs.
High-pressure water is sprayed from inside the roll, acting directly on contamination in the holes and on the inner shell wall.
The inside-out direction carries debris out of the roll — nothing enters the roll interior to cause secondary contamination.
Thoroughly removes fibres, fillers and scale from the drilled holes, restoring full hole patency.
With the holes clear, the vacuum distribution becomes uniform again and dewatering returns to design levels.
Custom-built for roll diameter, drilling pattern and machine type — suited to suction formers, press suction rolls and more.
