## Long description

The SpiroFlex insulated distribution box 12x75/200 W.2 (DWZ) is a compact air distribution component designed for duct connection in HVAC systems. It provides twelve 75 mm outlet branches and a single 200 mm main connection, combining airflow routing with thermal and acoustic insulation to reduce heat loss and noise transmission in ventilation networks.
Advantages

Its modular layout simplifies connection to circular ducts and facilitates balanced air distribution across multiple branches. The design supports easy installation in residential and commercial ventilation systems and is compatible with standard circular duct fittings.
Suitable for
Air distribution in residential ventilation systems
Branching and balancing ducts in commercial HVAC installations
Connecting multiple 75 mm flexible ducts to a single 200 mm supply or return
Retrofit projects where thermal and acoustic insulation around distribution points is required
Key specifications
Number of outlets: 12
Outlet diameter: 75 mm
Main connection diameter: 200 mm
Insulation: thermal and acoustic insulation integrated in housing
Compatibility: designed for circular duct connections and flexible ducts
Typical applications: supply or return air distribution within HVAC systems
How to use
Install the distribution box on a flat surface or suspend it within the ventilation route using appropriate hangers or brackets. Connect the 200 mm main duct to the central inlet using a compatible sealing method and attach each 75 mm branch duct to the outlet spigots, ensuring secure clamps or connectors to prevent air leakage. After mechanical connection, check alignment and seal joints with recommended tape or sealant for ventilation systems. Commission the system by measuring airflow at several outlets to confirm balanced distribution and adjust dampers or balancing devices if present.
Usage recommendations
For reliable performance, select matching duct diameters and use corrosion-resistant clamps. Maintain access space around the unit for inspection and balancing. Periodically inspect seals and insulation integrity, especially in high-humidity installations, to prevent condensation and preserve thermal efficiency.
