Flexible Use

The CAP-CT is a flexible multi-nozzle diffuser suitable for air supply in comfort ventilation systems for offices, shops, medical rooms and school classrooms. 


Quiet Operation

The CAP-CT combines high airflow capacity with a quiet operation. This makes it suitable for use in environments where unobtrusive ventilation is required.


Compact Design

The diffuser has a compact design with adjustable damper and flow measurement probes for supply and extraction. 


The CAP-CT is a compact, multi-nozzle diffuser with quiet operation allowing for use in a variety of public settings. Primarily designed for air supply in comfort ventilation systems for offices, shops, medical rooms and school classrooms, it can be installed in an open space under the ceiling. Superior air induction and mixing with small air flow volumes make it suitable for VAV ventilation systems. 

The diffuser has a compact design in galvanised steel. It is composed of a plenum box with a vertically from top oriented rubber gasket sealed circular connection and a diffuser plate with polymer nozzles. The nozzles allow for 360° rotation in the plane of the diffuser plate. This allows for the creation of the desired air discharge pattern. All of these parts are accessible from the outside allowing for measurement and adjustment without dismantling the diffuser. Two thread nuts in the upper part of the plenum box allow for straightforward installation on the suspended thread bar. Different sizes are available.
