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. SKU: N/A Category: Ventilation
