Zip-A-Duct is a modular, pre-engineered fabric duct product allowing HVAC contractors to quickly design an air distribution project in-house and then purchase the fabric air dispersion system from thousands of traditional HVAC wholesale distributors throughout the U.S. Designed for smaller to medium-sized, non-plan/spec ventilation projects, Zip-A-Duct is a time-saving, cost-cutting solution that’s applicable to 90% of retrofit and new construction ventilation projects.
Zip-A-Duct zips together onsite and cuts installation time up to 80% and materials/labor costs up to 50% versus spiral or rectangular metal duct alternatives. It is constructed of polyester-woven fabric available in 8 to 36-in. diameter components that are quickly installed with zippered connections aesthetically concealed under flaps for a smooth streamlined appearance. Components include custom elbows, custom lengths, T-fittings, inlets, endcaps, and eccentric reducers. Colors include white, grey, black, and blue.
Air volume ranges from 385 to 9,200-CFM depending on duct diameter. Air is distributed along the length through linear vents consisting of laser-cut orifices ranging from 1/8 to 1-in. diameter. Zip-A-Duct is suspended from aircraft cable-supported along the length with vertical cables and quid-adjust connectors. Once the cable is stretched and supported from the structure, the fabric sections and fittings simply clip onto the cable along the length and then zip together.
Optional, internal 360-deg. shape-retaining hoops are included to maintain a 100% inflated appearance even during idle supply air handler periods. The hoops consist of flexible fiberglass rods connected with pre-attached stainless steel couplings. Each rod is concealed inside its own interior fabric holding sleeve that’s undetectable from the duct’s streamlined exterior and minimizes friction losses inside the duct. The sleeve design is the HVAC industry’s first with easy-access external entry points that allow easy removal for laundering.
- Quicker response time than plan/spec fabric duct distribution channels;
- Linear orifices provide a more uniform air dispersion versus metal duct registers;
- Quick lead times can meet most project deadlines;
- A 2-CFM/sq. ft. airflow through the fabric’s factory-designed permeability prevents surface condensation formation;
- Air balancing is built into the design, therefore not required onsite;
- 10-year, non-prorated warranty.
