Functioning
The spark protection for the unit filtoo can be retrofitted optionally and consists of two components, the
baffle and the collecting tray.
The polluted air is sucked in via extraction elements (e.g. extraction arm) and gets inside the filter unit
via the air intake. There the air hits the baffle plate and is led along the baffle plate towards the collect-
ing tray. At the collecting tray the air deflects by 180°. Thus the air gets into the particle filter. Induced by
the deflection the bigger particles, as for exemple extinct spark particles, fall into the collecing tray and
stay there.

1. Function
The spark protection for the unit W3 can be retrofitted
optionally and consists of two components, the baffle
and the collecting tray
The polluted air is sucked in via extraction elements
(e.g. extraction arm) and gets inside the filter unit via
the air intake. There the air hits the baffle plate and is
led along the baffle plate towards the collecting tray.
At the collecting tray the air deflects by 180
o.
Thus the
air gets into the particle filter. Induced by the deflection
the bigger particles, as for exemple extinct spark par-
ticles, fall into the collecting tray and stay there.

3. Installation
3.1 Exchange of the clamping bracket
The previous clamping bracket is exchanged with the
two new supplied clamping brackets. The shape of
the previously used clamping bracket determines the
choice of the type to be installed.
When screwing the clamping bracket, the screw must
be tightened; but only to the point where the clamping
bracket is still movable. For this purpose it might be
necessary to exchange the screws against the ones
supplied alternatively.

3.2 Use of the plug-on-rubber
The supplied plug-on-rubber is only used with filtoo’s which have been manufactured since end of 2013
(see information on the type plate).
The plug-on-rubber supports the airflow along the baffle plate. Mount the plug-on-rubber at the inside of
the braces (see arrows). At the position where braces cross the plug-on-rubber has to be gashed.
The plug-on-rubber has no sealing function, but reduces the gap between baffle plate and the braces.
