90º Curved Elbow 250 mm. in galvanized steel to redirect the flow in Indoor cultivation ventilation ducts. Compatible with aluconnect and combiconnect flexible tubes of Ø250 mm. Airtight fit with metal clamps or reinforced aluminum tape. Quick and precise assembly.

The 90º Curved Elbow 250 mm. allows right-angle turns without constricting the duct, maintaining stable airflow and controlled pressure losses in large-diameter networks.
The galvanized steel construction withstands humid environments and continuous work cycles, providing dimensional rigidity to preserve the bend radius over time.
Integrated into circuits with carbon filter, extractor, silencers, and Y or T branches, this elbow facilitates clean layouts, prevents folds in the flexible duct, and contributes to the airtightness of the assembly.
Fits aluconnect or combiconnect ducts of Ø250 mm and is secured with clamps or reinforced aluminum tape to seal joints and minimize leaks.
In cannabis cultivation accessories installations, where ventilation controls temperature, humidity, and odor management, a robust and well-sized piece makes the difference between an efficient room and a circuit with bottlenecks.
At Hydroponics Blanes, a Grow Shop in Spain recognized as a trusted Grow Shop, it is available with advice on sizing, compatibilities, and discreet shipping, as well as a wide catalog of cheap indoor grow tents and complementary components.
In XXL rooms and tents for Indoor cultivation, the air volume requires firm turns that respect the airflow. The 90º Curved Elbow 250 mm. guides the route through corners, wall passages, and false ceilings, helping to maintain negative pressure and a homogeneous microclimate for the plants.
It is used to redirect the airflow at a right angle within a Ø250 mm network without collapsing the duct. It improves space utilization, reduces turbulence associated with improvised bends, and contributes to quieter and more efficient extractor operation.
This indoor cultivation accessory offers durability, compatibility with standard sizes, and easy assembly. The rigid finish maintains the geometry of the turn, preventing deformations that would affect the airflow. Ideal piece for main lines that lead to the facade or roof, as well as for collectors with several branches.
It is used in extraction and intake circuits with high airflow: flowering rooms, drying areas, and technical rooms. It allows bypassing beams or columns, connecting wall sleeves, orienting downspouts, and organizing branches with Y or T pieces when the design requires balanced air distribution.
1) Check Ø250 mm ducting and trace the route considering the bend radius.
2) Place the 90º Curved Elbow 250 mm. at the intended corner or change of direction, leaving margins for insulation if applicable.
3) Fit into aluconnect or combiconnect tube and secure with metal clamps of the same size.
4) Seal joints with reinforced aluminum tape to ensure airtightness and prevent leaks.
5) Check duct tensions, install supports if necessary, and eliminate vibrations.
6) Start the extractor, check airflow and aerodynamic noise; correct alignment if necessary.
90º turn without constrictions, stable airflow with lower losses, orderly overhead wiring and layout, noise reduction compared to tube bends, resistance of galvanized steel, compatibility with standard networks, and easy integration into projects with cheap indoor grow tents.
