The VENTIT distribution box cone 4xDN90 with a 125mm throat is a precision-engineered component for **high-performance air distribution** in residential and light commercial HVAC systems. It facilitates the transition from main supply lines to individual room ducts, ensuring consistent airflow and system balance with an optimized 90mm outside diameter interface.
Key Benefits
Precision Manifold Design
The 4xDN90 configuration enables installers to manage air distribution efficiently from a single 125mm throat, ideal for branching out from main ventilation unit lines.
Low Resistance Geometry
Internal surfaces are engineered to minimize friction, contributing to energy-efficient ventilation and maintaining quiet operation across the entire HVAC system.
Professional Installation
Standardized throat and port sizing allow for rapid assembly. Compatible with standard DN90 semi-rigid ducting and 125mm rigid air handling pipes.
Durable Build Quality
Constructed from high-grade materials that resist corrosion and mechanical stress, ensuring long-term reliability within the building's ventilation infrastructure.
Application & Compatibility
This distribution box cone is an essential component for system designers and HVAC installers working with central heat recovery units. It is ideally suited for residential projects where space-saving ducting is required without compromising airflow volume. The 125mm throat connects directly to the main supply or extract plenum, while the four DN90 ports distribute air to individual rooms. For optimal performance, ensure all connections are secured with appropriate seals to maintain system pressure and indoor air quality.
