The 200 mm Y Union. is a metallic branch designed to divide or unify ventilation routes in Indoor cultivation. With three Ø200 mm outlets and a bifurcation close to 45°, it distributes airflow evenly in cabinets and rooms that require multiple air destinations.

Manufactured in galvanized sheet metal, the Y Union 200 mm. provides rigidity, tightness, and long service life in extraction and intake networks. The 200/200/200 geometry maintains section continuity to minimize pressure loss and aerodynamic noise compared to improvised joints.
Fully compatible with 200 mm flexible ducts such as Sonoconnect, Aluconnect, and Combiconnect, as well as with carbon filters, silencers, and extractors of the same range.
The Y angle (≈45°) softens the change of direction, preserves flow, and reduces turbulence; something key when the goal is to maintain stable negative pressure for maximum aromatic discretion.
In networks with several branches, it is advisable to balance the flow with reducers, dampers, or flow regulators to achieve even distribution between branches. Quick installation using 200 mm clamps and aluminum tape with clean sealing that prevents leaks and odors.
Recommended piece for feeding two grow tents from an extraction box, diverting cold air from the air conditioner to two zones, or unifying returns in medium and large rooms.
Available at Hydroponics Blanes, a benchmark as a Grow Shop in Spain and trusted Grow Shop, with technical advice, discreet shipping, and a complete catalog of cannabis growing accessories and cheap indoor grow tents.
In indoor growing installations with more than one tent or separate zones, the Y Union 200 mm. allows you to branch ventilation in an orderly way. The two-way distribution helps eliminate heat pockets, improve gas exchange, and stabilize temperature and rH between adjacent spaces.
It is used to diversify air routes from a 200 mm main duct to two equivalent branches, or to merge two lines into one. It makes it easy to feed two rooms from the same extraction box, separate supply and return, divert flow to a drying room, or integrate auxiliary equipment while maintaining flow continuity and system efficiency.
Among cannabis growing accessories, this branch stands out for its mechanical stability and quick assembly. Galvanized finish prepared for humid environments, robust joints, and the possibility of disassembly for dust cleaning, joint inspection, or section replacement without drastic changes to the overall network design.
Recommended when expanding a room with a second tent, when there is only one exterior outlet for several zones, when distributing cold air from the air conditioner to two spaces, or when the plan requires branching returns to homogenize temperature and reduce stagnant humidity in corners and ceilings.
1) Plan the layout with a main duct and two Ø200 mm branches; measure lengths and anticipate support points.
2) Place the Y at the intended intersection, orienting the 45° branch towards the destinations to minimize sharp bends.
3) Insert Sonoconnect/Aluconnect/Combiconnect ducts into each opening and secure with 200 mm clamps.
4) Seal joints with aluminum tape for tightness and odor control.
5) If there are multiple branches, install reducers or regulators to balance flows and maintain negative pressure.
6) Support the network every 1–1.5 m with metal straps or ties, avoiding stress on the piece.
7) Check depression and total flow; adjust speeds on the controller or diameters with reducers until balance is achieved.
At Hydroponics Blanes the Y Union 200 mm. is available with expert support and fast delivery. Catalog of cheap indoor grow tents, ventilation, climate control, and cannabis growing accessories all in one Grow Shop in Spain.
