Decentralized ventilation | Mechanical ventilation system

Everyone deserves a good indoor climate

At Airmaster, we believe that everyone deserves a good indoor climate. It creates the best conditions for learning, being creative, developing, performing, and generally feeling good. That is why we want to improve the quality of the indoor climate for children and adults at schools, nursery schools, and office environments with our flexible and intelligent ventilation solutions.

World champions in decentralized ventilation
When it comes to ventilation, we are decentralized to the core. We have been working with decentralized ventilation for more than 30 years. We are a market leader and are committed to staying the world champion in our niche. With more than 120,000 units installed across Europe, we have helped many people achieve a better indoor climate.

What is decentralized ventilation?
Central ventilation transports air via large pipes and ducts from a central unit throughout the building to individual rooms. With decentralized ventilation, local air handling units are placed directly in each room to provide the best possible ventilation.

Improving your indoor climate quickly and easily.
Our decentralized units are assembled and installed in just a few hours directly in the room that needs ventilation. This permits installation in stages at a pace that suits your project and budget, without having to relocate the occupants of the premises. With our plug-and-play solution, you are guaranteed a better indoor climate quickly and easily.
You can customize the solution to your needs.
Our decentralized units are flexible and can be adapted to the structure, function, and needs of each individual room. We have both ceiling-mounted and floor-standing units, all of which can be customized and controlled according to individual needs. Our design and low-noise units do not steal the spotlight but adapt to the space and your needs.
You will have an overview and control wherever you are.
Our decentralized ventilation solutions can be connected to our cloud solution Airlinq Online, regardless of the number of units. This allows you to monitor and operate your units from any location - giving you an overview and control of your operations wherever you are.
You improve energy efficiency and protect the environment.
Our units ensure that you avoid unnecessary operation, as they ventilate when needed - in the rooms where it is needed. For example, you avoid unnecessary energy loss from transporting outside air, since the units are placed close to the outer wall. In addition, our high-efficiency counter-current heat exchangers provide high heat recovery. All in all, this results in highly energy-efficient ventilation that is much more environmentally friendly, as the use of building materials such as steel for ductwork is minimized.
You reduce the total cost of ownership via the operating budget.
Our units help you reduce energy costs in your operating budget. The total price of air handling units in a construction project is relatively low, while the subsequent operation of the units is costly. In collaboration with Artelia, we have prepared a LCA analysis in a casestudy which concludes that the totalCO2 footprint for a decentralized ventilation unit, including operation, is approximately 50% lower than a centralized solution over a period of 25 years. This means that, over time, a decentralized solution from Airmaster will be beneficial not only for our environment, but also for the total cost of ownership.
Complying with fire requirements easily and simply.
One of the advantages of our decentralized units is that the risk of fire and smoke spreading through the ventilation system is minimized, as the units serve only one fire unit. This makes it much easier to comply with statutory fire requirements, as our units can be installed without additional fire and smoke protection.

To ensure a good and healthy indoor climate, four main factors need to be taken into account

Acoustic conditions: Low-noise ventilation

In terms of acoustics, noise has a major impact on our indoor environment. Classrooms, daycare facilities, and office environments will naturally be noisy, but noise from technical installations can also be a major nuisance.
One of our core competencies is that our units are tested and designed with low-noise properties. We focus on minimizing noise through dimensioning and choice of materials. We also work on sound quality by limiting low-frequency noise through air-flow engineering design and the use of the latest technology.

Thermal conditions: Room temperature and humidity

In terms of thermal conditions, a comfortable room temperature and adequate humidity are key to a good indoor climate. In addition, the thermal indoor climate also has an impact on the performance and energy consumption of buildings. Our units have efficient counter-current heat recovery to ensure comfortable supply air temperatures, and we offer a wide range of heating surfaces for particularly cold climates.
We offer cooling modules that reduce high outdoor temperatures and humidity levels during hot summer periods. In addition, we pay particular attention to providing control of the supply air to ensure good ventilation of the whole room without creating drafts.

Atmospheric conditions: Fresh air and better air quality

Compared to outdoor atmospheric conditions, indoor air is often filled with harmful particles and chemicals. We can quickly feel the effects of poor air quality on our well-being. The air quality in a room depends, among other things, on the level of moisture, odors and pollutants from people, furnishings, and construction materials. Our units ventilate with fresh outdoor air and thus remove large amounts of particles, including viruses and bacteria. We also offer demand-management in the units according to the concentration of CO2 and/or VOC. The sensors are placed in the extract air stream of our units, which ensures the best average measurement for mixed ventilation.

Optical conditions: Lighting levels

During the optical indoor climate, conditions such as daylight incidence, illumination level and light quality are important. Daylight is considered important for our mental well-being, and building regulations require a certain amount of natural daylight. It is important to have an appropriate level of lighting at workplaces that is adapted to the task to be performed.

A good indoor climate creates a good life

Better indoor climate for school children

Good indoor air quality is a prerequisite for living good lives in the spaces we occupy. We spend most of our time indoors - at school, at work, or at home. That's why the quality of our indoor environment is important.

A poor indoor climate can cause headaches, tiredness, difficulty concentrating, malaise, and physical discomfort, such as coughing, itchy eyes, and allergies.

Fortunately, in recent years, our society has become more aware of the importance of our indoor climate. That is why more and more people are taking responsibility for creating a healthy indoor climate that helps our concentration, learning, health, and overall well-being.
