Buildings account for around 35% of energy consumption in Germany. while in the Technical Building Services As the energy requirements increase, so does the need for systems for the decentralized ventilation. In addition, the corona pandemic has led to an increased air cleaner demand led. We provide you with the latest new developments for both Ebm Pope and Qleanair before:

VDI-compliant air purifiers for schools and offices

22.06.2022 | Qleanair is one of the first suppliers of air purifiers to adapt its systems for good air quality to the new VDI expert recommendation adjusted. Schools and offices can now rely on using these air purifiers to maintain safe and healthy indoor air in accordance with guidelines.

With the Covid-19 pandemic, the demand for air purifiers also increased sharply. Because it is in many classrooms there are no adequate and modern ventilation systems, usually only the windows are opened. However, this is only beneficial to the air quality to a limited extent and in many schools it is not possible to open the window at all for safety reasons.

The Swedish manufacturer Qleanair complies with the new expert recommendation of the VDI (Association of German Engineers) with specifications for healthy indoor air in public buildings. In all likelihood, that one will in DIN and European standards be taken over. With the manufacturer's air purifiers according to VDI, public rooms now receive high-quality, recommended room air cleaning, which eliminates viruses, pollen, dust, particles, bacteria, allergens, odors and other pollutants.

Air purifiers for clean rooms in schools and offices

"Schools and offices are demanding environments with many aspects to consider. In addition to the ability to reduce aerosols, low noise levels and maintaining indoor comfort are key factors to consider when designing an air purifier for these environments. We are excited to launch our improved air purifiers according to the new VDI expert recommendation”, commented John Billing, Product Manager at Qleanair.

The VDI expert recommendation includes regulatory requirements for air purification performance, airflow, noise levels, room comfort and safety. The air purifier must Particulate pollution in the room removed by 30% within 90 minutes to have. Because there are also inadequate air purifiers on the market, the new recommendation supports organizations in finding highly efficient and high-quality air purifiers.

The upgrade kits for the air cleaners FS 30 HEPA, FS 70 HEPA and FS 70 Standard are equipped with important accessories that make the air purifiers compliant with the expert recommendation. The new air purifiers are highly efficient against viruses and bacteria. But they also effectively combat other common pollutants in schools and offices such as pollen, combustion particles and dust.

Qleanair is already in use with air purifiers in more than 75 German schools. “We welcome the new expert recommendation which we hope will raise national standards on air purification. It is positive to see the public sector leading the way in protecting people's health and we look forward to bringing clean and healthy air to more people in schools and offices,” says Christina Lindstedt.

This is what the VDI expert recommendation demands

The VDI recommendation contains the following Criteria for air purifiers, among which key issues are aerosol reduction, airflow, sound levels, indoor comfort, no generation of unwanted by-products and safety:

The air purifier must aerosol concentration in the room by 30% within 90 minutes.
The aerosol reduction must be low sound level done so that concentration and room comfort are not impaired. The sound level must not exceed 35 dB(A) for classrooms in schools and 45 dB(A) in open-plan offices.
The air cleaner and ventilation system must be cleaned at least four times an hour air exchange in the room make.
The air discharge through the air purifier must not be uncomfortable air turbulence generate in space.
There must be no high by-product values in the room such as Ozone, which is caused by UV-C radiation, ionization or plasma.
protection against against vandalism and unauthorized changing of settings.

High-performance insulation reduces wall thickness by 50 percent

By introducing VDI compliant air purification devices, Qleanair has taken another important step towards clean and healthy air for the public sector. That Business Model of the premium supplier of indoor air cleaning solutions is based on rental agreements for modular solutions with a full service offer.

Compact fan for decentralized living space ventilation

09.06.2022 | The need for systems for decentralized living space ventilation is increasing in new construction and renovation of buildings. They ensure the necessary exchange of air without just dissipating the heated room air. Ebm Pope has developed a new reversible compact fan for this purpose. The Axirev 126 is an energy-efficient and quiet push-pull development.

New buildings and modernizations are increasingly being energetically insulated and thus sealed airtight. push-pull systems for air exchange prevent damage to the building fabric and health impairments due to poor breathing air quality.

Push-pull fans convey the used room air to the outside in a specified period of time (push). The fan built into the fan then changes the direction of rotation by reversing (pull). A integrated heat accumulator absorbs the thermal energy from the exhaust air during the process. In the pull phase, it is released into the fresh outside air and flows into the building preheated. In order to meet the health requirements, a filter cleans the incoming outside air of dust and pollen. The balanced ventilation operation takes place according to the application by two devices per zone or room.

Quiet living room fan with high efficiency

The Axirev 126 fan was specially developed for decentralized home ventilation. Its shape is unique: The almost symmetrical wing design ensures that the characteristic curve and the amount of air conveyed are almost identical in both directions of rotation. The patented wing design with its distinctive blade tips and the openings at the wing tips also minimizes the noise components induced by head gap vortices, which reduces noise emissions.

Smart domestic waterworks also for outdoor applications

Thanks to the integrated EC motor the fan works with high efficiency even in partial load operation. The efficiency is up to 7% higher with a lower noise of up to 5 dB(A) compared to the previous model. The maximum volume flow is 132 m³/H. Its steep characteristic allows the Axirev 126 to be efficient even under high wind loads outdoors.

The compact fan for decentralized living space ventilation has a diameter of 126 mm and is 26 mm high. The speed can be set between 500 and 4200 rpm^-1 infinitely variable. The complete plug-and-play system is also suitable for retrofits existing living space ventilation devices.
