## Summary description

Massa Diffuser Pop-up Type 1 (model SB657) is a pop-up style diffuser designed for redirecting airflow or liquid flow in installation systems. The unit is identified by manufacturer model SB657 and EAN 5904647810655. Suitable for use where a compact, deployable diffuser element is required in ventilation, drainage or similar routing applications.

## Long description

The Massa Diffuser pop-up Type 1 model SB657 is a compact deployable diffuser designed to redirect airflow or liquid flow within installation systems. Its pop-up mechanism allows the diffuser element to remain retracted when not needed and to extend into the flow path when routing or dispersion is required. The design is intended for applications where space is limited yet a controllable, localized change of flow direction or dispersion is necessary.
Advantages
The pop-up construction provides a low-profile solution that minimizes obstruction when retracted while offering a sturdy, reliable diffuser surface when deployed. The diffuser is suitable for integration into ventilation ducts, drainage lines, or other routing systems where a temporary or adjustable flow redirection is required. Its compact footprint and straightforward mechanical action simplify installation and maintenance in confined spaces.
Suitable for
Local redirection of airflow in ventilation or HVAC systems
Dispersion or rerouting of liquid in drainage and plumbing installations
Applications requiring a retractable diffuser element in tight or concealed spaces
Systems where occasional deployment of a flow-directing device is needed
Key specifications
Pop-up deployable diffuser element suitable for airflow or liquid flow control
Compact, low-profile design when retracted for minimal obstruction
Mechanical deployment mechanism for straightforward operation
Intended for integration into ducts, channels, or piping with limited space
How to use
Install the diffuser in the appropriate section of the ductwork, drainage channel, or piping according to the system layout, ensuring a secure fit and alignment with the intended flow direction. Keep the diffuser retracted when flow redirection is not required. Deploy the pop-up element to introduce localized dispersion or change the flow path as needed, then retract after use. Follow any system-specific sealing and fixation procedures to maintain leak-free operation and structural stability.
Usage recommendations
Use the diffuser within the design limits of the surrounding installation; verify compatibility with the media (air or liquids) and operating conditions. Regular inspection and cleaning of the diffuser element and deployment mechanism are recommended to ensure reliable operation, especially in environments with particulates or sediment.
