This allows control of air velocity, improves distribution uniformity, and limits stratification phenomena.<\/p><p>Lightweight, modular, and easy to install, fabric ducting adapts to many building configurations and meets the requirements for airflow comfort, aeraulic efficiency, and maintenance of HVAC installations.<\/p><p>At F2A, each fabric air diffusion system is designed specifically for
