220x90mm to 150mm Round Plastic Duct Straight Adaptor

The 220 System has been specifically designed to meet the increasing demand for larger plastic ducting systems. This allows for higher flowrates and increased air movements as required for certain properties. The Verplas 220 range has comparable airflow to the 150mm Round Duct but is designed to be low profile to fit in between ceilings and floor slabs or on top of kitchen units.
