The market´s greenest choice

Energy-efficient components

Thanks to their energy-efficient components and low energy consumption for air transport, X-Vent ventilation systems have some of the lowest energy consumption rates on the market. The systems are based on the decentralized concept whereby only two holes are required through an external wall or the roof, keeping the amount of ducting to a minimum.

With long ducts, the running costs are invariably high, while transporting air over long stretches also results in heat loss. Extensive ducting also increases the risk of leaks in the ventilation system, impairing efficiency.

Airmaster’s products are carefully designed down to the smallest detail with low internal pressure loss, resulting in some of the lowest energy consumption rates on the market for air transport

Counter-flow heat exchangers

The X-Vent systems feature counter-flow heat exchangers which offer the market’s best heat recovery of the extracted air. By virtue of its decentralized installation, the heat exchanger sits directly in the room and thereby close to both the exhaust air and the supply air. This avoids heat being lost in long duct systems.
The heat exchangers we use are documented according to EN308 and have a minimum efficiency of 85%. This means that the unit only needs supplementary heating in special situations.

EC motors


X-Vent II is equipped with the latest and most advanced motor technology, ensuring low energy consumption and a long service life. The unit’s motor control system ensures one of the lowest energy consumption rates for air transport on the market. X-Vent II has an SFP value of less than 0.9 kW/(m3/s). This is extremely low in relation to the statutory requirements in the Danish Building Regulations (BR10) which state an energy consumption of < 2000 joule per m3 (SFP < 2.0).

The choice of F wheels also means low revolutions and thus low energy consumption and low noise levels.  


Ventilation not required throughout the building
In addition, there are many operational advantages in having a system in each room as it enables you to simply and cheaply demand-control the ventilation rather than ventilating the entire building all at once. This is all too evident from the bottom line when drawing up energy accounts.
