Unit sizes


The VENTUS VVS modular air handling units are made of polyurethane panels covered with sheet metal mounted on an internal skeleton made of metal profiles.

The VENTUS VVS units have an extensive sealing system, among others, sealing fins ensuring labyrinth sealing, a thermal insert that allows to break the thermal bridge, as well as a roofing system.

Ergonomic closing system.
Aesthetic, comfortable and ergonomic handles, ensuring tightness of the closure of the inspection panel
Fan section cage
Increased longitudinal stiffness of the structure.
Steel frame
High profile resistance to deformation.
Aluminium structural posts with an additional sealing fin and a thermal break
Casing with broken thermal bridges as standard - ensures no condensation on the unit components.

The fin at the perimeter of the inspection panel provides labyrinth sealing - currently the most effective solution on the market, mainly used in laboratory equipment.

The solution consisting in the use of a symmetrical channel cut filled with sealant, which ensures 100% tightness at the connection of the post with the casing structure.

Energy efficiency

The VENTUS VVS modular air handling units meet the highest energy-efficiency requirements.

The devices can be equipped with various heat recovery options:

  • rotary heat wheel,
  • counter-flow hexagonal recuperator,
  • cross-flow plate heat recuperator,
  • run-around coil
  • wrap-around heat pipes

The maximum recovery efficiency reaches 87%. 

All units are available with multi-functional controls that performs advanced energy-saving functions based on measurements of air quality parameters.

Energy recovery
Depending on the configuration, energy recovery can be achieved by:
- high-efficiency rotary heat exchanger with EC motor, including double wheel concept.
- high-efficiency cross and hexagonal recuperators.
- run-around coil.
- wrap-around heat pipes.


Controls in the VENTUS VVS air handling units regulates all utility parameters and functions of energy optimisation based on the measurement of air quality parameters.

Visualisation or a remote HMI Advance desktop, which enables remote control of the unit, are available as standard.

Visualization on control panel
VTS Factory visualisation enables monitoring as well as remote control of the unit operation.
Controls in VENTUS VVS units is based on the uPC3 controller.


The proper functioning of the air handling unit depends on the effectiveness of the applied filtration.

Specialists recommend changing filters 2 to 4 times a year. Original, high-quality filters for VENTUS AHUs are available in the VTS online store.

You can easily choose filters for your AHU. Use the search engine, entering the VTS AHU number to order the correct set of filters.


The system of guides allows for a simple and quick replacement of filters.
In VENTUS air handling units, we use panel filters (G4) as preliminary filters and pocket filters (M5, F7 and F9) as the last stage of filtration. Filters in a galvanized steel frame.
