Shape Retention Options

Shape Retention Options
Shape Retention Options ensure better looking ducts in periods when the ventilation system is turned off. With Internal 360° Hoops the duct is kept round regardless of whether the system is active; with All-in-One Support only a slight change of the circular shape occurs when the air is shut off. Both accessories also minimize the shock associated with inflating ducts in systems without a soft start, otherwise known as "duct pop".

Internal 360° Hoops

The Internal 360° Hoops are mounted in sleeves on the inside of the ductwork creating a closed circuit around the circumference. This ensures an aesthetically pleasing duct that is kept open if the airflow is turned off. The hoops are removable for easy laundry. Internal 360° Hoops are available in duct systems from Ø155 mm [Ø6 in] and up. The hoops come pre-installed from the factory on ducts up to Ø660 mm [Ø26 in]. For diameters above Ø660 mm [Ø26 in], the suspension fiberglass rods are added on site. Adding the hoops is an easy process, as they simply glide in place.

Installing FabricAir® Internal 360° Hoops

This animation shows you how to easily install the Internal 360° Hoops shape retention option. The hoops are factory installed up to Ø660 [26in]. The Internal 360° Hoops ensures 360° support regardless of the duct diameter. It is easy and quick to install and removal the hoops and requires no special tools. The fiberglass rods are simply inserted from the outside of the duct. The shape retention solution keeps the duct visually appealing even when the airflow is off - the duct is kept open during shutdown (100%).

All-in-One for better looking ducts

All-in-One Support (AiO) consists of semi-circular hangers, made from anodized aluminum, sewn into pockets on the exterior of the duct at fixed intervals. These come pre-installed from the factory, which significantly reduces installation time compared to the systems offered by other manufacturers. The All-in-One support are easily removable for maintenance purposes. The appropriate suspension support depends on the diameter of the duct. The AiO Support will cover 180° of the duct’s circumference up to Ø1220 [Ø48”]. For diameters above Ø1220 [Ø48”], hanger coverage decreases due to shipping constraints. All-in-One provides additional support for 90° elbows.
