Indoor Comfort

A well-designed air distribution system ensures the equal distribution of air throughout an indoor space. This eliminates hot and cold areas, making the environment more comfortable for occupants. Optimal air distribution helps maintain consistent temperature and humidity levels, preventing discomfort and ensuring a pleasant indoor environment.

Adaptation and Zoning

A good air distribution system can easily adapt to changes in a building’s layout or occupancy requirements. It can accommodate renovations or extensions without significant modifications. What’s more, zoning options enable selective airflow control for different areas, providing personalised comfort and increased energy efficiency by refreshing only the necessary spaces.

Silent Operation

An efficient air distribution system ensures no noise distribution caused by the indoor ventilation system and eliminates cross-talk effects. This is especially important in spaces where low noise is crucial for productivity, concentration and comfort. A well-designed system blocks out noise interference during work, rest, or communication.

Range of Air Distribution Solutions

Air distribution delivers fresh air in indoor spaces equally and effectively. It helps maintain a healthy environment by ensuring effective and silent ventilation, as well as temperature control. It comes in all shapes and sizes – so there’s a perfect system for every project. Our flexible plastic ventilation pipes are available in three main sizes: round ventilation pipe 75 mm and 90 mm, flat ventilation pipe Flat 51×138 mm. In addition to flexible ventilation pipes, the system also includes air distribution manifolds, pressure relief boxes for end elements and pre-insulated air intake/exhaust air pipes.

Make your installation process as simple as possible and let yourself and your customers reap the full benefits of better air quality in their homes and commercial buildings. The Zehnder RapidLock® Connection makes connecting air distribution ducts safe, simple and efficient, and ensures easy maintenance.
