Throttle
The throttle regulates the airflow in the raw gas line. It can be operated electrically or
manually and is available in different sizes, available with one or more valves, in round or
right angular shape or e.g., in a special flat design when space is limited. The drives are
equipped with a potentiometer to signal the position of the flap.
Skimmer: Funkabscheider
The skimmer is used to separate coarse particles and sparks from the air stream. For this
purpose, it is installed in front of the filter in the raw gas pipe. The raw gas enters the
skimmer and is directed in a horizontal rotational movement. The heavier particles are
carried by gravity to the outside and collide against the outer wall. From there, they slide
down, where air baffles cut off the air layer that is carrying heavier particles and passes
them into the settling area. There, the particles separate and are collected in a container
or big bag. The air that has been offset in rotation exits the skimmer via a center-mounted
tube. The red cover can be removed for maintenance purposes and replaced if
necessary.
Piping
The piping has optimized airflow for less turbulence and pressure loss. They are
designed and constructed in accordance with the required air quantity and adapted to
the particular structure of the building. The pipes are made of welded 3 mm plates and
painted both on the outside and the inside.
Junction box
The aerodynamically optimized junction box connects the hood with the exhaust duct.
Various designs are available. The junction box is often connected to a throttle valve,
then a transition piece, from rectangular to round, and then the round raw gas pipe.
