use
To extend Type TAV cranked
sleeve to create a greater distance
between inlet and outlet level.
introduction
Where airflow is required for a
specific area at lower level via a
cavity wall,a cranked sleeve is
employed with a cavibrick.
The (cranked)Type TAV
Telescopic Adjustable Ventilator
is used for such purposes and
provides a five brick courses
maximum difference between
inlet and outlet levels.
Where a greater vertical
difference is necessary,an
extension sleeve is available.
Vertical sleeves are available in
two standard lengths,with special
lengths available to order.
Sleeves can also be supplied to
extend the Type TAV horizontally.
Specify clearly if required so
correctly dimensioned section is
supplied.See next entry if you
wish to connect pipe to Type TAV.
data
•Black polypropylene.
•Lengths 300mm and 450mm.
•Special lengths to order.
•Packed in boxes containing
10no.
•Smaller quantities available.
Horizontal extension sleeves
In instances where it is desirable
to horizontally extend the lower
TAV aperture inwardly (to
accommodate an unusual inner
skin dimension or feature),an
appropriate horizontal 600mm
long extension sleeve is available.
For distances exceeding 600mm
horizontally,we recommend use
of a Type TAV to Round
Connector that permits use of
nominal 100mm plastic pipe.
