The 200 mm T Union allows you to branch or unify ventilation lines in Indoor cultivation with firm and airtight connections. Made of galvanized sheet metal, it works in Ø 200 mm networks, useful for cabinets and rooms with multiple air destinations and the need for balance.

The 200 mm T-Union is a metal connector 200/200/200 designed to split an extraction or intake main into two symmetrical branches, or to join lines at a common point without significant losses.
The galvanized sheet body provides rigidity and resistance to the typical humidity of growing environments, reducing vibrations and maintaining the useful section of the duct.
Fully compatible with flexible ducts such as Sonoconnect, Aluconnect, and Combiconnect of Ø 200 mm, as well as silencers and carbon filters of the same range.
In installations with several branches, the use of reducers, gates, or flow regulators helps balance the flow between branches and maintain negative pressure when working with a carbon filter.
Installation is quick with clamps and aluminum tape, achieving tightness and odor control. Recommended part for distributing air conditioning between rooms, supplying two grow tents from an extraction box, or unifying returns in professional rooms.
Available at Hydroponics Blanes, Grow Shop in Spain, and Trusted Grow Shop, with technical advice, discreet shipping, and a wide range of cannabis growing accessories and cheap indoor grow tents.
In indoor growing projects with several zones, the 200 mm T-Union facilitates an organized and efficient network. It allows you to connect an extraction box to two rooms, split cold air from an air conditioner, or create parallel returns to homogenize temperature and rH.
It is used to diversify air routes with continuous section, distribute flow between two zones, unify lines in a common main, separate supply and return, or branch to a drying room without improvisation. All with a durable and airtight metal fitting.
Among cannabis growing accessories, the 200 mm T-Union stands out for its mechanical robustness and ease of maintenance. Long-lasting galvanized finish, solid joints, and the possibility of disassembly for dust cleaning or section replacement without altering the general design.
Recommended when expanding a room with a second 200 mm tent, when a single external outlet must serve several rooms, when distributing cold air from a split to two zones, or when the design requires branching returns to avoid thermal stratification and stagnant humidity.
1) Plan the layout: define main and branches of Ø 200 mm, lengths, and number of bends.
2) Place the T at the intended intersection, aligning the openings with the axes of the ducts to minimize turbulence.
3) Insert Sonoconnect/Aluconnect/Combiconnect ducts into each opening; secure with 200 mm clamps.
4) Seal joints with aluminum tape to ensure tightness and odor control.
5) In networks with several branches, install reducers or regulators to balance flows between branches.
6) Support the network every 1–1.5 m with metal straps or ties, avoiding stress on the T-piece.
7) Check depression and total flow; adjust speeds on the controller or diameters with reducers until balance is achieved.
