Poly Y Duct Connector | Hydroponic Ventilation Splitter 150mm–350mm Australia

Poly Y Duct Connector. Hydroponic Ventilation Splitter for Grow Room Airflow Systems (150mm–350mm)

Poly Y Duct connectors are engineered to split, combine, or redirect airflow within hydroponic ventilation systems. Designed for low-resistance air transfer, these fittings enable efficient redistribution of airflow across grow rooms, tents, and HVAC setups without significant pressure loss or turbulence.

Used in conjunction with inline fans and flexible ducting, Y connectors allow precise airflow management across multiple branches, improving environmental stability and system efficiency in controlled grow environments. Available in six size configurations from 150mm to 350mm to suit all standard hydroponic ventilation setups.

Key Benefits

• Low-resistance airflow redistribution. Engineered internal geometry minimises turbulence and pressure drop at the branch point, maintaining inline fan efficiency across split ducting runs.
• Splits or combines air streams efficiently. Enables a single fan to serve multiple grow zones, or combines two intake streams into a single extraction point for flexible system design.
• Multiple size configurations for scalable systems. Six size variants from 150mm to 350mm cover all standard grow tent and grow room ducting configurations.
• Compatible with carbon filter systems. Supports multi-branch filtration setups where a single carbon filter serves multiple extraction points or grow zones.
• Durable poly construction. Rigid polymer body maintains shape under airflow pressure, preventing collapse or deformation in continuous ventilation applications.
• Simple installation. Standard duct sizing ensures direct compatibility with flexible ducting, inline fans, and carbon filters without modification.

Ventilation Performance in Hydroponic Systems

• Airflow redistribution. Splits or combines air streams to direct ventilation precisely where required within the grow environment.
• System flexibility. Adapts ventilation layouts to suit grow room design, tent configuration, and multi-zone growing setups without requiring additional fans.
• Pressure management. Low-resistance internal profile maintains airflow with minimal static pressure loss across the branch junction.
• Ventilation optimisation. Supports balanced intake and extraction systems for stable temperature and humidity distribution across the canopy.
• Carbon filter integration. Compatible with multi-branch filtration configurations for complete odour management across multiple grow zones.

Available Size Configurations

• 150mm – 150mm – 150mm. Equal three-way split for compact grow tent systems using 150mm ducting and inline fans.
• 200mm – 150mm – 150mm. Reduces a 200mm main duct into two 150mm branches for stepped airflow distribution.
• 200mm – 200mm – 200mm. Equal three-way split for medium grow room systems using 200mm ducting throughout.
• 250mm – 200mm – 200mm. Reduces a 250mm main duct into two 200mm branches for high-volume stepped distribution.
• 300mm – 250mm – 250mm. Large-diameter configuration for commercial grow rooms requiring high-volume multi-branch airflow.
• 350mm – 300mm – 300mm. Maximum capacity configuration for large commercial ventilation systems and high-output inline fan setups.

Frequently Asked Questions

What size do I need for Poly Y Duct Connector?

Ducting and ventilation fittings are sized by internal diameter in millimetres (100mm, 125mm, 150mm, 200mm). Always match your fittings to your fan and filter flange size. Standard grow tent setups use 100mm or 125mm ducting for small tents and 150mm or 200mm for larger tents running higher-output fans and carbon filters.

What material should my ducting be made from?

For most indoor growing applications, flexible aluminium ducting is the standard choice — it is lightweight, easy to route around obstacles, and resistant to the humidity levels found in grow tents. Acoustic or insulated ducting is recommended if noise reduction is a priority. Rigid ducting offers lower airflow resistance but is more complex to install.

Does Poly Y Duct Connector ship fast within Australia?

Yes — Poly Y Duct Connector ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
