Rectangular-to-Rectangular Adapter

The AD-PDK rectangular adapter is designed to connect two rectangular ventilation ducts. The adapter features flanges at both ends for secure and airtight installation. The steel sheet is reinforced with transverse corrugation to enhance rigidity and withstand high air pressure and velocity.
The AD-PDK allows installation of ventilation systems with arbitrary changes in all dimensions and optional offset in two directions. For type 6 adapters, offsets E and F must be specified; for other types, the offset is 0.
