SFM - Vane fastener

Turning vanes are installed in rectangular ductwork, e.g. in bends or junctions, in order to optimise the air flow. The turning vanes effectively reduce turbulence and consequently, pressure losses and noise. The use of turning vanes is specified by DIN EN 1505 for bends with an angle greater than 45°. As such, the number of vanes depends on duct dimensions. Turning vane fasteners, available in galvanised steel and stainless steel, are ideal for fixing the turning vanes. In order to reduce the leakage, all our fasteners are already fitted with a mounted sealing washer
