The Flexaust FX-400 Portable Heater DuctThe FX-400 lightweight heating duct is perfect for a wide range of applications, including construction sites, commercial and residential work areas, cement drying, dehumidification, event tents, and other climate control environments where temporary and portable heating or cooling is needed. The Flexaust FX-400 Portable Heater Duct is made with a high-strength sewn single-ply polyurethane coated polyester hose, featuring a spring steel wire helix and a heavy-duty PVC wear strip for added external abrasion and drag resistance. The polyurethane coating enhances puncture, abrasion, and tear resistance, and provides an easier-to-clean surface. The lock stitch construction creates a stronger duct allowing for better performance. This moisture-resistant and UV-stabilized duct is designed to prevent mold and mildew, and it comes standard with wire ropes, belted cuffs, and storage straps for easy attachment to the heater. It is a heavy-duty solution for your temporary heating needs.
