Five good reasons for selecting the VEX4000

There are many good reasons for choosing a VEX4000 unit for your next project. Here are just five of them.

Extremely high energy efficiency

With the VEX4000 you can satisfy the international 2020 requirements by means of EC motor technology and a condensation efficiency level exceeding 90 %. Patented adaptive pressure control that reduces energy consumption compared to traditional pressure control methods. (CAV, VAV, DVC)

Minimal noise level

One of the quietest fan impellers on the market combined with EC motors provides extremely low noise levels.

Compact design

Compact, modular design which can even be supplied as a SPLIT solution for narrow access routes.

Simple installation

Your unit is assembled before or after delivery with assembly fittings and detailed mounting instructions. Assembling a ventilation unit has never been easier!

Easy configuration with unique design program

With EXselectPRO you can put together your own unit with the modules you need for your project. This gives you a unique product - regardless of the task in hand.

Design your ventilation system to your own specification

With capacities from 1,050 to 36,000 m³/h, you will always find a solution to suit your needs

With so many combinations, there's always a solution

The many modules in the VEX4000 series each have their own function, but can be adapted to each other. This means you can put together your own ventilation unit to fit your exact needs and wishes, while still preserving the same overall width and height. You can also choose whether your unit will be a LEFT or RIGHT version.

– advanced control for optimum operation

The integral EXcon control system in the VEX4000 controls airflow, heating and cooling, but it is the user who determines how and when the control system will switch between the integral functions.

Integral functions in the control system

  • Night-time reduced duty
  • Alarm log and data log
  • Control using a day, week or year plan
  • Extended operation
  • External forced operation with run-on time
  • Alarm e-mail
  • Summer night cooling
  • Outdoor air temperature compensation
  • Set summer/winter operation
  • Digital inputs for:
    • External resetting of alarms
    • External low, medium and high speed
    • External start/stop

Control methods

  • Constant pressure
  • Constant airflow
  • Constant CO2
  • Fan Optimiser
  • Zone control
  • Constant motor speed %
  • Adaptive pressure control (patented solution for energy optimisation of VAV systems)
  • External 0–10V with supply air/extract air slave

Temperature regulation

  • Constant supply air temperature
  • Constant extract air temperature
  • Constant room temperature
  • Constant difference between extract air and supply air
  • Summer and winter compensation
  • Recirculated air heating (option)
  • Summer night cooling
World-class energy efficiency with patented adaptive pressure control
43% energy savings compared to VAV
VEX4000 units are supplied with the EXcon control system, which allows the use of EXHAUSTO’s patented adaptive pressure control (aDCV). Adaptive pressure control continuously optimises pressure in the unit in relation to the requirements in the building, which reduces energy consumption compared to traditional methods for pressure regulation (CAV, VAV and DCV).

Operate the system when you want, where you want

Setting and control is executed using the web server from a PC, smartphone or tablet. Network communication supports BACNet via TCP/IP and modbus via RS485 or TCP/IP. As an option, communication with LonWorks can also be supported.

Unique project planning with EXselectPRO

Whatever your project, the VEX4000 is up to the job, and with our design program EXselectPRO, you can combine and compose the ventilation system to fit your own requirements. At the same time, the program provides you with detailed technical data, dimensional sketches and energy calculations and labels. Easily and simply!

Installation has never been easier

Once you have configured you’re VEX4000 unit, you can choose to have it delivered in three different ways.

1. The unit is supplied ready-assembled

If the unit is supplied ready-assembled, EXHAUSTO will make sure that all modules are correctly connected and assembled on the base frame.

2. Modules are supplied separately

In many cases it can be a benefit to receive the modules individually, for example if they need to be transported through doors or up stairways. For this reason, the VEX4000 has been specially designed for ease of assembly.

3. SPLIT solution

The air handling unit is supplied 'flat-packed' for assembly onsite, so even larger air handling units can be transported where access is restricted.

Certified performance

The VEX4000 series takes account of the industry's principal rules and standards.


VEX4000 is Eurovent-certified, and as part of the certification process, the data in EXselectPRO is being verified.


VEX4000 is RLT-certified, and as a part of the certification process, the data in EXselectPRO is being verified.

VDI 6022

VEX4000 has been developed in accordance with the German Hygiene Standard VDI 6022. We can provide you with advice in how to ensure there is optimal access for inspection and cleaning of your air handling unit’s sub-components and thus prevent any harmful micro-organisms occurring in the air handling unit’s airflows.

VEX4000 - a product of experience and know-how

The VEX4000 development is based on the same knowledge and expertise in making quality products which the market has known and prized for decades.

The VEX5000 series

is known for its solid, well-made construction and not least for the ZerAx fan, without doubt the most energy-efficient solution on the market.

The SMART series

with its wide capacity range and advanced control system, has been a leader on the Norwegian market for many years.

The VEX series (VEX 100/200/300)

with its compact design and optimum energy utilisation, is the result of the knowledge, expertise and innovation which has put EXHAUSTO at the forefront of the ventilation field for over 50 years.

In other words;
we have combined the best of the three series into a new single series - the VEX4000 series - which with capacities from 1,050 right up to 36,000 m³/h and unique configuration options covers practically the whole ventilation field.
