The VENTIT Prechodový box AST 2xDN90/125 is a precision-engineered air distribution component designed for high-efficiency **HVAC systems** utilizing semi-rigid ducting. Featuring dual DN90 inlets and a Ø125mm main connection, this **400mm transition box** ensures balanced airflow and minimal pressure loss in residential heat recovery installations.
Key Benefits
Modular Air Distribution
Part of the AirFlex ecosystem, this plenum box allows for flexible routing of semi-rigid ventilation ducts in tight ceiling voids or wall partitions.
Extended 400mm Reach
The 400mm neck length provides installers with additional depth flexibility, making it ideal for thick floor slabs or suspended ceiling structures.
Dual Port Efficiency
By splitting the airflow into two DN90 lines, this unit supports higher volume air exchange while maintaining the quiet operation required for residential comfort.
Professional Grade
Designed for HVAC contractors who demand reliable, standardized connections that reduce installation time and eliminate the risk of airflow bottlenecks.
Technical Application & Compatibility
This transition box is specifically developed for modern **heat recovery** systems where air handling precision is critical. It serves as the bridge between the main air distribution branches and the terminal points. It is fully compatible with DN90 (90mm outer diameter) semi-rigid polyethylene (PE) ducting. For optimal performance, ensure all connections are secured with original seals to maintain system pressure.
