Airsystem

The AIRSYSTEM mechanical ventilation system consists of individual components that are matched to construction- and production-specific requirements using the modular principle and are assembled in an installation-friendly manner. The modules are made of 1 mm thick aluminium sheet with inner corner fold. The connection is made by means of profile flanges that are screwed to the corner connections. Profile flanges and corner connections also serve to stiffen the duct. Air intake is via roof and wall hoods. Appropriate modules must be provided for mixed air, recirculated air and heating operation.
The AIRSYSTEM can be set up in two different ways. While in the ISOVENT mixed air unit with ventilator, filter and, if necessary, heating coil are combined in one unit, these functions can also be managed decentrally by individual modules. The DIGOVENT ventilator module used in this case only fulfils the ventilator function and, with an output of 2000 to 9000 m³/h, also has a much lower air volume throughput than the ISOVENT. 

In addition to the simple duct sections in straight form and as curved elements, there is a wide range of other functional modules that can also be integrated into the duct system as individual modules for smaller systems. In addition to the heating coil, these include a roof or wall hood, the mixed air module and the filter module. In heat recovery systems, a heat exchanger is integrated into the system. 
Another module that is already present in the ISOVENT, but is also available as an individual module, is the mixed air module. Via an actuator, this unit mixes cool fresh air with the already heated recirculated air. The percentage of fresh and recirculated air can be controlled or regulated via a duct sensor. 

Filter modules filter the air and heating coils heat it. Both optional modules can be arranged decentrally or integrated in the ISOVENT. The air outlet at the workplace is provided via three different variants, depending on requirements: 

Where a draught through the system is not disturbing or the air is only extracted, normal ventilation grids are sufficient. These are available as a variant with a single-row louvre design for adjustable, vertical air deflection and with a double-row louvre design for horizontally and vertically adjustable deflection.
Displacement outlet grids, on the other hand, change the flow behaviour of the air so that it is no longer perceived as a draught. This is similarly influenced by textile ducts, where the air flows through air-permeable fabric and is thus evenly distributed around the outlet surface.
