Rectangular-to-Round Duct Adapter

The AD-PSKK rectangular-to-round adapter is designed to change the cross-section of a ventilation duct from rectangular to round. This fitting ensures a reliable and airtight transition between ducts of different shapes without compromising the aerodynamic performance of the ventilation system.
The adapter allows installation of ventilation systems with arbitrary dimensional changes and optional offset in two directions. The round spigot is manufactured as a standard nipple connection, ensuring quick installation and secure joining with round ducts.
The standard adapter length is L = 300 mm. Upon request, a symmetrical adapter with a reduced length can be manufactured according to project requirements.
