Union in T 355 mm.

T-junction 355 mm. Unify ventilation ducts

The T-junction 355 mm. is a metal branch 355/355/355 designed to split an extraction or intake main into two symmetrical branches, or to join lines at a common point without reducing airflow.

The rigid body of galvanized sheet metal withstands humid environments and mechanical stresses typical of large installations, maintaining section continuity and reducing vibrations.

Fully compatible with flexible ducts such as Sonoconnect, Aluconnect and Combiconnect of Ø 355 mm, as well as carbon filters, silencers and commercial extractors of the same diameter.

In networks with multiple branches, it is advisable to balance airflow using reducers, dampers or regulators to maintain stable negative pressure and filter performance.

Installation is quick with clamps and aluminum tape, achieving airtightness and odor control.

Recommended piece for supplying two grow tents from one extraction box, distributing cold air from an air conditioner in large rooms, or unifying returns in professional spaces.

Indoor Growing T-junction 355 mm.

In large-scale indoor growing projects, the T-junction 355 mm. simplifies system distribution and balance. It allows you to branch a main duct into two zones, split air conditioning supply, and create parallel returns to homogenize temperature and rH in partitioned rooms.

What is the T-junction 355 mm. for?

It is used to diversify ventilation routes, distribute airflow between two areas, unify lines into a main, separate supply and return, branch to a drying room or connect auxiliary equipment while maintaining flow continuity and aerodynamic efficiency.

Indoor growing accessory T-junction 355 mm.

Among cannabis growing accessories, the T-junction 355 mm. stands out for its robustness, clean installation and easy maintenance. Long-lasting galvanized finish, solid joints and the possibility of disassembly for dust cleaning, joint inspection and section replacement without altering the network design.

When to install T-junction 355 mm.?

Recommended when expanding a room with a second 355 mm tent, when a single external outlet must serve several rooms, when distributing cold air from a split to two work areas, or when the room plan requires branching returns to eliminate thermal stratification and stagnant humidity.

How to use T-junction 355 mm.

1) Plan the layout with main and branches of Ø 355 mm, defining lengths, curves and support points.
2) Place the T at the intended intersection, aligning openings with duct axes to minimize turbulence.
3) Fit Sonoconnect/Aluconnect/Combiconnect ducts into each opening and secure with 355 mm clamps.
4) Seal each joint with aluminum tape for airtightness and odor control.
5) In networks with several branches, install reducers or regulators to balance airflow between branches and maintain negative pressure.
6) Support the network every 1–1.5 m with metal straps or ties, avoiding stress on the T-piece.
7) Check negative pressure and total airflow; adjust speeds on the controller or diameters with reducers until optimal balance is achieved.
