Assembly

Suspension of circular ducts:

Suspension of circular ducts.The suspension with the steel ropes (steel line with PCV transparent cover) are used for assembly of the circular ducts. Together with the fabric ducts the customer receives the set of assembly elements. Every ordered duct has the steel ropes enclosed of the length equal to the duct length + 3 m. In case of the necessity to use ropes of different length, we kindly ask you for underlining that fact in the order. The standard method of suspension is to use one or two steel ropes. The double suspension should be used from the duct diameter of 400 mm in order to obtain the circular section.

Method of duct fastening

The ends of steel rope are fastened on the hooks or holders mounted in two opposite walls of the room. The rope assembly points should be placed at the height of 40 mm above the upper edge of the fabric duct. One end of the rope should be fastened to the holder in the wall. The second end should be fixed by means of the bottle screw and tighten the rope. In case of duct of length exceeding 5 m it is necessary to use the vertical joists placed every 4-5 m to keep uniform duct suspension level in the whole length. After completing the described actions the fabric ducts should be unpacked and suspended using the spring hooks. In case of ducts consisting of the sectors, you should remember about adjusting the sectors in a way enabling joining them together with the in-sewn zip fasteners. The initial sector of the fabric duct should be put on the tin fragment of the system supplying the air and secure it against falling down with the steel clamp strip. On the customer’s special request it is possible to deliver the duct fastening system using the lifting slings made out of stainless steel.

Suspension of semi-circular ducts:

The semi-circular duct can be mounted while using the steel ropes as in case of the duct with circular section or in case of the assembly in the ceiling while using special velcros. In case of the assembly in the ceiling the enclosed angle sections should be fixed. To the fixed angle section you should attach the self-adhesive industrial Velcro. The fabric duct has the in-sewn Velcro and therefore the duct assembly is very easy. The inlet sector of the fabric duct should be put on the tin fragment of the system supplying the air and secure it against falling down with the steel clamp strip.
