use
To provide airflow in and out of
roof space via the soffit board.
Suitable for introduction into
existing soffit boards to fulfil
airflow requirements.
Also suitable for new build
applications.
introduction
The CSRV differs from the
standard CSV as it has a deep
body that protrudes up into the
soffit box.The airflow apertures
are positioned around the sides
of the deep body ventilator rather
than through the top.This
arrangement results in a far
greater airflow rating per
ventilator.Thus a lesser number
are required to fulfil the statutory
airflow levels.
The Type CSRV can be used on
most pitches of roof (appropriately
spaced)and self-secures when
pushed into a 70mm circular hole.
Always ensure airflow via a soffit
ventilator can reach the parts of
the roof intended.
