ROTOCLEAR S3

Figure13
A suitable measuring device is available as an
accessory.
Check the sealing air pressure at the connection
box (Fig. 11-A) using the manometer (Fig. 11-B)
(accessory). To do this, screw the adapter plate
ofthemanometerontotheopenconnectionbox
and regulate the supply line until the necessary
pressure is reached.
The supply pressure can be adjusted to approx.
0.5 bar with the supply lines provided. Depending
on the distance between the feed and the Roto-
clear S3,apressureof0.3–2.0 barmaybeneces-
sary to achieve the required back pressure at the
connectionbox.
Precise adjustment reduces the air consumption
as well as the corresponding costs.
Please ensure that the sealing air supplied is
dry, clean and correctly adjusted.
If necessary, pre-treat the sealing air using a ser-
viceunitwithamulti-stagefiltersystem.
Pay attention to the requirements for the sealing
air which are indicated in the section "Specifica-
tions".
Ensure that all screw connections and cable
glands are screwed tightly in place and that no air
can escape into the supply line.

Installation without sealing air
Thesuctioneffectoftherotatingwindowcreates
an air flow that prevents cooling lubricant from
entering the unit under moderate conditions
inside the machine tool.
Air must be able to flow through the connection
boxandtheprotectivehoseintotheunittomain-
taintheairflowcreatedbytherotationofthewin-
dow. Instead of connecting a sealing air line (Fig.
10-G) to the pneumatic plug-in connection (Fig.
8-H), the line must be removed or the connection
left open.

plug connection is not covered or closed.
A perfectly clear view cannot be guaranteed. The
view can be affected, for example, by humidity,
temperature differences and the air supply to
the unit. A sealing air supply can be connected at
any time if the conditions do not allow for a clear
viewand,forexample,theunitormachineryglass

Special case: Replacement kit for S
and S2
A sealing air supply is not provided for the stan-
dard version of the replacement kit for S and S2.
