In industrial ventilation and air handling systems, cleaning and maintaining filters is essential to ensure the energy efficiency of the system. A clean filter provides low pressure drop, stable airflow, and reduced electrical consumption, helping to keep the system consistently efficient and reliable. Why a clogged filter consumes more During operation, dust particles accumulate in […]

In many German and Austrian homes, balanced ventilation with heat recovery is described as a KWL system (Kontrollierte Wohnraumlüftung) or Wärmerückgewinnungsanlage. In English, we often use the term HRU – Heat Recovery Unit. Whatever the name, one element is always the same: good filters are essential to protect both air quality and the heat exchanger. […]

Replacing the filters of a controlled mechanical ventilation (HRU) system is a simple operation, but it requires some preliminary steps: identifying the filter section and the direction of the airflow. In a classic double-flow HRU, the filter sections are generally two: one for supply and one for exhaust. In some models, return filters and grille […]

In recent years, the need to improve living standards and the quality and comfort of buildings has grown significantly, together with the need to limit heat losses as much as possible and therefore reduce energy consumption. As a result, both in new buildings and in the renovation of existing ones, we are seeing an increasing […]
