VEX4000
Air handling unit
With VEX4000 you can meet the energy requirements of the future via EC motor technology, high-performance heat exchangers and integrated reversible heat pump.
COMPACT FLEXIBILITY
The VEX4000 series covers 10 sizes, which means the optimal size of unit can be found for your ventilation requirements, and the many different modules give you the freedom to put together your own air handling unit to meet your exact project requirements.
All sections are mutually compatible in each model size, allowing the complete unit to preserve the same overall width and height. The units are available in LEFT and RIGHT versions.
EXCON CONTROL SYSTEM
All VEX4000 units are available with integrated control systems for advanced control of airflow, heating, cooling, humidification, etc. However, it is also possible to order VEX4000 without a control system.
EXHAUSTO's patented adaptive pressure control, which constantly optimises the pressure in the unit to match what the building requires, makes it possible to reduce your energy consumption even further than the traditional pressure regulation methods on the market (CAV, VAV and DVC).
EXSELECTPRO
VEX4000 is calculated and configured using the Eurovent and RLT-certified calculation program EXselectPRO .
The program is used for configuration and energy calculations according to project requirements. The output consists of detailed technical data, dimensional sketches and energy calculations and the associated labels.
Product advantages
- Extremely energy-efficient air-handling unit
- 13 modules, which can be combined to meet your exact solution
- Eurovent and RLT-certified

VEX4000 is a range of highly energy-efficient, reliable and cost-effective AHUs with enough flexibility to meet most requirements for ventilation solutions for offices, schools, hotels, hospitals, stores, and industrial facilities. VEX4000 units are compact and can be assembled with a high degree of flexibility because they are composed of modular ventilation components. The many possible variations allow great freedom for combining and customising individual solutions.
EXHAUSTO OFFERS THREE DELIVERY OPTIONS:
The units are supplied ready-assembled and Exhausto ensures that all modules are correctly connected and assembled on a base frame.
The modules are delivered separately, an advantage if they have to be transported inside the building. For this reason,VEX4000 has been specially designed for ease of assembly.
The unit is delivered as a SPLIT version, where the unit is delivered unassembled as a flat pack. This means that even large units can be transported through small doors and then assembled on site. The SPLIT solution is more expensive, since specially trained EXHAUSTO technicians are required.
