PST195-R Venturi Tube for Uniguard 8 – Easy Installation for All Duct Sizes
The PST195-R is an innovative venturi tube for Uniguard 8, designed for simple installation of air sampling probes in ventilation ducts – with no cutting or adjustments required. Starting in March 2025, the PST195-R is included as standard in the Uniguard 8 packaging, eliminating the need for a separate order.
In combination with Uniguard 8, the PST195-R is certified according to both European (VdS) and American (UL) standards for smoke detection in ventilation systems.
For duct diameters under Ø 200 mm, a separate mounting bracket is required.
