The Prechodový box AST DN90/125 is a critical component for high-performance air distribution, enabling a seamless transition between flexible DN90 ducting and Ø125 mm terminal outlets. This plenum box is engineered to maintain **maximum airtightness and low pressure drop**, ensuring that your ventilation system operates at peak energy efficiency while maintaining superior indoor air quality.
Key Benefits
Precise Dimensions
Designed specifically for DN90 DN90 (90 mm outside diameter, 75 mm inside diameter) semi-rigid pipes transitioning to a standard Ø125 mm air valve or diffuser.
Quiet Operation
The aerodynamic design helps reduce noise generated by airflow at the terminal points of the ventilation network.
Installer Friendly
The 400mm length provides ample flexibility for adjustment during the rough-in stage of construction.
Durable Materials
Manufactured from high-quality materials that ensure long-term stability and resistance to corrosion or degradation.
Application & Compatibility
This transition box is ideal for residential and light commercial HVAC projects utilizing semi-rigid air distribution systems. It is typically installed in ceiling voids or wall partitions to connect the main air supply or extract runs to the final air valves. For optimal system performance, we recommend pairing this component with ourcentral heat recovery unitsand high-qualityfiltersto maintain clean, energy-efficient airflow throughout the building.
