The VEX 200 brings fresh, filtered air into the building and recovers heat from exhaust air using its high-efficiency heat exchanger. The incoming air can be heated and/or cooled using a comprehensive range of coils.
- The ALC™ (Automatic Leakage Control) option is the patented solution that prevents the propagation of viruses by air handling units equipped with rotary heat exchangers. It measures, checks and constantly adjusts the pressure difference between supply and return airflows to ensure that no stale air comes into contact with the clean air produced by the unit.

The aluminium rotary heat exchanger with low pressure drop and a temperature efficiency of 80%.
The rotor control comprises a step motor with motor control.
Efficiency:
- Rotor with wave height of 1.4 mm - very high efficiency
- Rotor with wave height of 1.8 mm - very high efficiency
The combination of modern EC motors and the EXHAUSTO motor controller delivers extremely low energy consumption and with the EXstream impeller, a high output is achieved.
An energy label that states the energy class of the air handling unit in relation to defined operating conditions is available via our product calculation programs.

MECHANICAL PERFORMANCE:
According to DS/EN 1886 and certified by Eurovent:
- Casing strength: D1 (M)
- Airtightness under negative pressure at -400 Pa: L1 (M)
- Airtightness under positive pressure at +700 Pa: L1 (M)
- Filter bypass leakage: F9 under negative and positive pressure
- Thermal transmittance: T2 (M)
- Thermal bridging factor: TB3
The cabinets are made from Aluzink AZ185 class C4 and insulated with 50 mm mineral wool. This results in low noise emissions to the external environment/installation location.
The panel construction minimizes the formation of thermal bridges in the air handling unit.
The motor sections are mounted in vibration dampers, which reduces noise in the ducts and eliminates the need to fit flexible connections between the unit and the duct system.
The motor sections can be pulled out for easier servicing.
The motors are of type EC and are extremely efficient. They comply with the requirements of the Ecodesign Directive.
EXstream performance:
The units are equipped with EXHAUSTO EXstream impellers, one of the leading air fan impellers on the market in terms of low energy consumption and low sound level.
The fan impeller rpm and the number of vanes have been optimised so that the “vane frequency” is in the 500 Hz band. This means that fewer/smaller silencers are required than normal and it costs less to sound proof at frequencies of 500 Hz than it does with frequencies of 125/250 Hz (the typical range).
The easily accessible connection box with built-in switch disconnector and control system fuses ensures easy access for connecting and service.
The mounting base has feet with an adjustable height.
The base is an accessory for VEX240/250, but standard on the other models, where the unit is assembled at the bottom by using the base, and via trunk fasteners at the top.
VEX200 series can be supplied with panel filters and bag filters.
Filter class in acc. with EN779:
Panel filters: Coarse 85% (M5) or ePM1 55% (F7)
Bag filters: ePM10 60% (M5) or bag filters ePM1 60% (F7).
With some projects, limited space means that internal transport of the air handling unit is difficult or impossible. This is why the VEX200 is available as a split version. It means that the air handling unit can be assembled and tested at the factory as normal – just without sealant. The air handling unit can therefore be easily taken apart at the installation site, transported as single sections, assembled, sealed and commissioned.
