Rubber-Cal Air Ventilator Heavy-Duty 12-in x 300-in Vinyl Flexible Duct

The "Air Ventilator Heavy-Duty" ventilation flex hose is a highly durable air ventilation duct that is well suited to industrial air movement applications. This flexible ventilation duct is made with a thick PVC vinyl coated polyester fabric that is reinforced with a spring steel wire helix and external wear-strip. These physical features make it ideal for withstanding the rigors of industrial ventilation ducting. The spring steel wire helix in each of these heavy-duty ventilation ducts gives them a stronger form and a degree of flexibility. It can help prevent the air hose from being crushed or deformed. The external wear-strip on the outside of this durable air ventilation hose is meant to provide an added layer of protection against physical abrasion. With these great structural components, this flexible ductwork will last for longer periods of time. The biggest differentiator that separates these air ventilation ducts from others is its thicker and heavier PVC fabric material. Although the spring wire ...
