Union in Y 125 mm.

Y-Union 125 mm. Metal branch in indoor grow

Constructed from galvanized sheet metal, the Y-Union 125 mm. offers rigidity, tightness, and long service life in extraction and intake networks. The 125/125/125 geometry maintains section continuity to minimize pressure loss and aerodynamic noise.

Fits flexible ducts such as Sonoconnect, Aluconnect, and Combiconnect, as well as carbon filters, silencers, and 125 mm range extractors, creating clean and tidy branches.

The Y angle (≈45°) softens the change of direction compared to abrupt joints, preserving flow and reducing turbulence.

In installations with several branches, it is advisable to balance the flow using reducers or flow regulators to maintain negative pressure and even distribution, which is key when the system includes a carbon filter and outlet to the outside.

Recommended assembly with 125 mm clamps and aluminum tape for tightness and odor control. Ideal piece for feeding two tents from one extraction box, diverting cold air from air conditioning to two rooms, or unifying returns in compact rooms.

Indoor Grow Y-Union 125 mm.

In indoor grow projects with more than one tent or several zones, the Y-Union 125 mm. allows you to branch ventilation without improvisation. The two-way distribution helps eliminate heat pockets, improve gas exchange, and stabilize temperature and rH between adjacent spaces.

What is the Y-Union 125 mm. for?

It is used to diversify air paths from a 125 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.

Indoor grow accessory Y-Union 125 mm.

Among cannabis growing accessories, this piece stands out for its mechanical stability and quick assembly. The galvanized finish resists the ambient humidity typical of rooms and tents, and allows disassembly for dust cleaning, joint inspection, and section replacement without drastic changes to the general network design.

When to install Y-Union 125 mm.?

Recommended when expanding a room with a second tent, when there is only one external outlet for several zones, when distributing cold supply from an air conditioner between two spaces, or when the layout requires branching returns to homogenize temperature and reduce stagnant humidity in corners and ceilings.

How to use Y-Union 125 mm.

1) Plan the layout with a main duct and two Ø125 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) Fit Sonoconnect/Aluconnect/Combiconnect ducts into each opening; secure with 125 mm clamps.
4) Seal joints with aluminum tape to ensure 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.
