Coupling 200 mm
The 200 mm coupling is a heavy-duty connector for joining two 200 mm ventilation ducts. Designed for professional systems with high airflow. The robust build handles the forces at play with this large diameter. Essential when extending or repairing 200 mm duct runs. Order at plantandflower.be.
Coupling 200 mm – heavy-duty connector for professional ventilation
The 200 mm coupling joins two Alu-Dec 203 mm ducts together. At this professional size a solid connector is not optional — the air pressure and duct weight demand it.
Professional size, professional approach
Systems running 200 mm ducting serve commercial grow facilities, greenhouses and industrial environments. When extending a run or replacing a damaged section, the coupling is indispensable. Its inner diameter matches the duct exactly, so there is no restriction or added resistance.
Fitting large-format ducts
Push each duct at least 7 cm over the connector — extra overlap matters at this diameter. Secure both sides with a 60–270 mm clamp and check for leaks. Support the duct near the coupling with a hanging bracket to relieve pulling forces.

How do I prevent a 200 mm coupling from coming loose?
Use ample overlap (at least 7 cm per side) and tighten the clamps firmly. Support the duct just before and after the coupling with hanging brackets so the duct's weight does not pull on the joint. This is especially important on horizontal runs.
