Flexible Ducts

Flexible ducts provide a bendable path for directing air in commercial HVAC, ventilation, portable cooling, portable heating, exhaust, and recirculation applications. Facilities teams, installers, and maintenance crews use them to make air-routing connections where fixed ductwork is not the right fit, including heating and cooling runs, dryer and bathroom applications, temporary blowing or exhaust setups, ceiling connections, and confined-space ventilation work.

Start by matching duct diameter, length, and connection style to compatible equipment or the planned air-routing setup. HVAC options include 14- and 18-inch ducting in non-insulated constructions, plus a 14-inch insulated R-4.2 option with an acoustic inner liner for quieter airflow paths. For portable cooling or heater applications, select ducts made for the specific equipment and required diameter, including 12-inch options and 20-inch heater ducting. Ventilation and exhaust ducting is available in 16- and 20-inch PVC constructions with features such as steel-wire helixes, wearstrips, end cuffs, outdoor-focused UV, mold, and mildew protection, and compressible storage. Also consider included installation components such as clamps, flanges, or grommeted tabs. For specialized setups, choose a ceiling duct kit for compatible air purifiers or a manhole entry device system that maintains airflow while helping keep a confined-space opening available for entry and exit.
