What this bin holds

Our duct reducer connector helps create a smooth airflow transition between different sized ducts. It joins an 8-inch ventilation line to a 4-inch line.

This duct reducer is made from PP material, which handles moisture and resists wear. We make it fire-resistant and pressure-resistant so it will not deform. The large end measures 200 mm (7.87 inches) inner diameter and the small end is 110 mm (4.33 inches) inner diameter. The overall height is 128 mm (5.04 inches) with a 4 mm (0.16 inch) thickness.

Who takes it home

Folks use this duct reducer to connect equipment like bathroom fans, range hoods, or dust collectors to their main ventilation systems. We make installation simple: just connect the ends of the reducer with the appropriate sized pipes. Be sure to check your duct sizes before ordering and confirm they can be used in the -10°C to 70°C temperature range.
