A person requires at least 30 cubic meters of fresh air per hour in order to feel well. This means that in modern residential buildings with hermetically insulated outer shells, quiet and efficient ventilation systems are a must. Germany's DIN 1946-6 construction standard requires that all new houses and refurbished older houses include a ventilation system. A controlled home ventilation system with heat recovery is generally recommended. Centrifugal fans like the ZAvblue from ZIEHL-ABEGG are perfect for the job. Centrifugal fans produce higher pressures and can reach optimal efficiency even with high volumetric flows.
The ideal home ventilation unit should do its job reliably without disturbing the occupants. In addition to generating minimal noise, the fans also need to be energy efficient.
With our ZAvblue series, ZIEHL-ABEGG has developed highly efficient fans for home ventilation that not only operate extremely economically, saving large amounts of energy, but are also significantly quieter than comparable products from other manufacturers. The fans' 3D blade geometry minimizes air loss, and their small dimensions and variety of sizes allow these blue "volume miracles" to fit into any ventilation system.
The "acoustic star" among our fans for home ventilation is the ZAvblue RH20V, which, along with other features, sets new noise generation standards. It operates significantly more efficiently compared to other fans for ventilation systems in residential buildings, and at the same time is dramatically quieter - fans generally being the noisiest component of home ventilation units, this represents a real benefit for all users and occupants. Even though a lot of people seem to grow accustomed to disruptive fan noise in their homes, it remains a constant acoustic stress factor that affects well-being and can even have an impact on health.
The features of the ZAvblue RH20V include a biomimetic blade design for high-efficiency air feed and compact dimensions that enable problem-free installation even in most compact ventilation systems. The ZAvblue RH20V performs excellently even in the tightest installation conditions, for example, by further improving static efficiency. We're especially proud of its acoustic values: We succeeded in reducing the ZAvblue RH20V to as low as 4 dB on the intake and pressure side, which represents a genuine noise emission revolution for home ventilation fans. It's no wonder these values represent an entirely new standard for residential ventilation systems and modern controlled home ventilation. The impressive acoustic performance of the ZAvblue RH20V is made possible first and foremost by its high-efficiency, high-tech ECblue055 motor. The ECblue055 makes a name for itself with a strong performance packed into extremely compact dimensions, making it compatible with many ventilation systems, regardless of space limitations. The motor's easy handling and flexible cable guide make for user-friendly installation and contribute to lasting, efficient, energy and cost-saving ventilation for living spaces.
Climate and ventilation technology has to provide reliable, fault and failure-free performance. But acoustics in the workplace are also extremely important, because noise and unpleasant sounds disturb concentration and "get on people's nerves", thereby negatively impacting on safety and other factors. ZIEHL-ABEGG fans are significantly quieter than comparable models from other manufacturers - a result of our unique blade design that ensures optimal air flow and aerodynamics, thereby making our fans not only significantly quieter but also considerably more efficient.
With our ZAvblue fan series and ECblue motor range, you can rest assured that you've made the right choice. They reduce energy consumption in home ventilation to a minimum, in addition to the time and effort needed for initial installation or for retrofitting existing ventilation systems. Our blue technology naturally also meets all of the requirements placed on modern home ventilation units by the market, your customers, and the relevant legislation. ECblue motors comply with EU energy efficiency directives and have efficiency ratings significantly above those required by the IE4 Super Premium Efficiency Class.
Our whisper-quiet fans for home ventilation also benefit from the advantages of EC technology. Fans equipped with an EC drive perform significantly more efficiently than AC fans, while also consuming less power. Connection is easier ("plug & play"), and thanks to its compact design the motors require far less space.
