Rotoclear S3
Rotoclear S3: the spinning window that cleans itself
Chips fly, coolant sprays — and your view into the workspace stays crystal clear. The S3 spins contamination away by centrifugal force, so there's no stopping mid-cut to wipe the glass.
Self-cleaning by centrifugal force
The rotating disc throws off chips and coolant instantly — the view stays clear while the machine runs.
No obstructing bar
Unlike conventional rotating windows, the S3 has no center fixing bar blocking your line of sight.
Less scrap, less downtime
See the cut as it happens. Catch problems early instead of opening the door and stopping the spindle.
Technology leader
Rotoclear is the world's technology leader in its segment — proven in metal-cutting CNC and semiconductor fabs.
Two mounting versions
Screwable for polycarbonate windows on milling machines; adhesive for bonding directly to laminated-glass or polycarbonate windows on mills, lathes and mill-turn centers.
Replace a Visiport — or any older spin window — with a Rotoclear system.

Technical facts
Rotor coating, sealing air, impact testing, adhesive and installation clearance at a glance.
Rotocoat anti-stick coating
With the Rotocoat anti-stick coating, the disc fouls more slowly, and coolant and dirt come off more easily. Especially recommended for machining aluminum.
Sealing air
Under moderate conditions the S3 runs without sealing air. For Rotoclear's full leak-tightness guarantee, sealing air is connected.
Ballistic-tested
Rotoclear ballistic-tested the S3: with the bonded flange, the machine window's retention capacity was not reduced — on machining centers per DIN EN ISO 16090-1:2019-12 and on lathes per DIN EN ISO 23125:2015-04.
Elastic 2K adhesive
The adhesive version bonds with an elastic two-component (2K) adhesive. On polycarbonate, a dedicated primer is applied first to protect the window and improve bond strength.
Installation clearance
The S3 needs 34 mm (1.34 in) of space behind the machine window.
