The AC Infinity AC-SDR86 provides a gradual transition between 8-inch and 6-inch ventilation lines. Its tapered cone design helps maintain smooth airflow when connecting components of different sizes, while the rigid steel body resists deformation in high-volume systems.

The 6-inch end features a raised ridge lip for improved grip when securing flexible ducting with a clamp. The wider 8-inch end has a flat brim for a clean, flush fit against compatible fan collars, filters and solid duct ports.

Key Features

  • 8-inch to 6-inch transition: Connects larger fans, carbon filters and duct components to 6-inch flexible ducting.
  • Tapered airflow path: Provides a gradual size change to help reduce turbulence and unnecessary airflow restriction.
  • Galvanised steel construction: Offers rigidity and resistance to moisture, corrosion and elevated exhaust temperatures.
  • Raised 6-inch collar lip: Helps flexible ducting and worm-drive clamps hold securely in place.
  • Flat 8-inch brim: Creates a clean, flush connection against compatible equipment collars and solid duct ports.
  • Bidirectional use: Can be used as a reducer from 8 inches to 6 inches or as an increaser from 6 inches to 8 inches, depending on the airflow direction.
