Turning VaneSystem
Square bends shall be fitted with turning vanes, with a
maximum spacing between the vanes of 60mm. They shall
have an inner radius of 50mm and the maximum length of
unsupported vane shall be 1250mm. The completed turning
vane assembly shall be fitted into the duct by mechanically
closed rivets or bolts.
DS104 fixing tool supplied individually, replacement tips
(DS105) are available.
Designed to provide economical air turns.
Smooth external face thereby reducing friction loss and noise generation.
Vane is roll formed from a single strip to alleviate problems of splitting.
Continuous seam joint forms a rigid section, adding strength to theassociated bend.
‘Fastrac’ fixing track is prepunched at 60mm centres to ensure constantspacing of vane.
Unique ‘Fastrac’ fixing tool allows rapid assembly without the need for riveting or spot welding.

Measure the diagonal of the ductwork bend to obtain the cutting length of the ‘Fastrac’fixing track for the aerofoil turning vane assembly.
From the first full tag, measure 30mm from the centre line of the fixing hole and cut thefixing track, ensuring that the first tag is left complete.
From the cut end measure the required length of fixing track less 30mm. From the lastavailable full tag, measure 30mm from the centre line of the fixing hole and cut the fixingtrack. (Do not cut through the next tag)
Bend the tags 90deg on the fixing hole centreline ensuring they are bent in the samedirection as the bead of the fixing track.
Cut the turning vanes using the internal height of the duct less 6 to 8mm. Push all thevanes onto one section of fixing track with the curve of the turning vane away from theopening left by the tag.
Beginning at one end, enter the first tag into the turning vane and progress along eachtag until all of the tags are entered into the turning vane. Using a mallet or hammer, tapthe fixing track tags into the turning vane until all of the tags are fully entered.
To connect the fixing track and turning vane together, insert the fixing tool into the fixinghole with the curved edge of the cutter towards the seam in the turning vane.
Using a mallet or hammer tap the fixing tool to cut the turning vane and lock the turningvane onto the fixing track tag.
Fit the completed turning vane assembly into the duct with the first turning vane set at60mm from the inside throat of the bend.
It may be necessary to trim the fixing track after the last tag, before the completed turningvane assembly will fit into the duct in the correct position.
