You can now manufacture your own flexible ducts easily and economically
Flexible ducts are used in the field of air conditioning and ventilation technology. Flexible ducts are often used here because, unlike rigid ducting, they can be easily adapted to the structural conditions on site. Tight spots, bends and sharp curves do not cause any problems for flexible ducting. Ideally, flexible ducts used in central ventilation systems are corrugated on the outside and smooth on the inside so that dust cannot accumulate and they are easy to clean.
You can manufacture these flexible ducts yourself with HAFLEX duct winding machines; in your warehouse, in your own workshop or even in a vehicle on site! Flexible ducts made with HAFLEX duct winding machines lead the way in terms of technology and quality and set the standard in markets worldwide. They are extremely elastic and pliable, which makes them very flexible. The flexible duct can not only be compressed to its minimum size, but also extended to its maximum length. In this way, it adapts very well to suit the building’s requirements.

+ Cut while duct is running.
+ Nominal widths 50–650 mm.
+ Incl.: 5 m long special duct guide and storage table
+ Cutting lengths ranging from 1 to 5 m
Automatic cut length control: The machine is slowed down to the optimum speed for cutting at the first light barrier. Simultaneously, a pneumatically actuated disc brake is applied to the coil to prevent it from overrunning.
The second light barrier triggers the sawing process. A special saw blade cuts without any chips, keeping the duct and the rollers clean. When the cutting process is complete, the cut duct is ejected into the chute and the machine accelerates back up to working speed.
A counter registers the number of cuts made so that the required number of cuts can be pre-set. Detectors stop the machine when the coil is empty or when the chute is full. Saw stroke and duct ejection are carried out by pneumatic cylinders. Customer requires air connection for 5 bar dry air. Incl. safety device: the saw stops automatically if an unauthorised person approaches the sawing area. More information available on request.
