Circular straight sleeves

In order to isolate vibrations caused by air handling units, fans or other equipment connected to air ducts, it is highly recommended to install a flexible connector joint between the outlet of these devices and the airduct. It is necessary to select an airtight and flexible cloth, with good weathering qualities and one which will withstand the temperatures inside and outside the duct. Duct being generally made of steel, the main difficulty is  to fasten the cloth to it in order to obtain a perfectly airtight joint.
Clim circular straight sleeve connectors are perfect for this job.
   
The circular straight sleeves can be produced for any diameter. They are made from Polyurethane cloth strips (M0 and 400° C/2h classified) 160mm wide and the ends are sewn with a strong, high-temperature thread. Each sleeve is supplied with two suitable clamps. Assembly takes place by sliding the sleeve over the external diameter of the circular duct and its matching part and clamping each end. This is simple and efficient and affords perfect airtightness.
