Quietflex HPDFlex Duct (High Pressure)

Quietflex® HPDFlex™ Duct is able to satisfy the demands of high pressure HVAC applications by being rated for up to –2 inch W.C. negative and +16 inch W.C. positive static pressure. This high pressure duct has a resilient metallic, polyester-vapor barrier with a special “rip-stop” scrim reinforcement. It also uses Johns Manville Formaldehyde-free™ insulation, which helps reduce overall formaldehyde exposure. Furthermore, HPDFlex™ Duct continuously inhibits the growth and subsequent spreading of various bacteria, fungi, mold and mildew with an antimicrobial coating, Agion®, on the inner core. This provides a naturally effective solution to combat microbial growth by employing a silver-based technology.
