This 4in, 6in, 8in, & 10in Duct Wye Y Splitter features an innovative center wall design that eliminates backflow by dividing the single bottom port. It maintains efficient airflow through dual top ports, each at approximately half the volume, preventing air from reversing into the opposite port. For secure installation, use at least three circular duct clamps to fasten the ducting firmly, and consider using optional duct tape for added grip and stability. Ideal for professional HVAC applications demanding reliable air distribution without backflow concerns.
