It goes without question that airlines require a very durable ducting product that can perform under rigorous conditions. Failed ducting would create a tremendous health risk to ground-service workers during waste removal from an aircraft. The ducting attaches to the aircraft via a portal on the underside and connects to a portable collection device that contains the waste after removal.
There are two types of waste extraction: gravity and vacuum-assist. ABC manufactures ducting for both applications. Typically, gravity-fed extraction is used primarily in North America, while vacuum-assist is more common at international airports.
