Airflow is proud to announce that we have introduced a new outdoor line to supplement our hugely successful Duplexvent Rotary MVHR range: the Duplexvent Rotary-N.


The Duplexvent Rotary-N are all-purpose rooftop units that can improve the indoor air quality of various different commercial premises such as schools, restaurants, office blocks and warehouse whilst protecting the health of those working within the building as well as the fabric of the building itself. The compact design of the Rotary-N allows for a discrete installation and helps you to maintain an aesthetically pleasing design of the premises.

The Duplexvent Rotary-N helps to reduce the property’s energy costs thanks to its highly efficient rotary heat exchanger that can recover otherwise wasted heat energy and use it to pre-warm the incoming filtered, supply air. This means that the building’s heating isn’t warming the workplace as much as normal and in turn can reduce the energy bills of the property. This brand new range comes in 7 different models and is able to extract from 1550m3/hr (431 l/sec) to 16700m3/hr (4639 l/sec) with impressive sound levels from just 34dB(A).

Following on from the launch of our new Duplexvent Rotary-N range of commercial MVHR units, Airflow have also expanded our range of the existing Duplexvent Rotary range of compact, indoor commercial MVHR units with rotary heat exchangers.

With 7 units from you to choose from, there’ll be something to meet your ventilation needs. They are ideal for schools, offices and halls and will improve the quality of air circulating through property. The Rotary range can supply up to 16700m3/hr (4639 l/sec) from an unnoticeable 34dB(A).

All Duplexvent Rotary and Rotary-N units can filter out small airborne pollutants such as pollen or dust thanks to the unit’s ability to be fitted with G4, M5 or F7 air filters. This helps to maintain a healthy indoor air environment for those within the building. By maintaining a healthy indoor air environment, you protect from indoor air pollution, which research shows can affect productivity, concentration levels and in worst cases even cause severe health problems.

All units have 85% thermal efficiency thanks to the highly efficient rotary heat exchanger. Duplexvent Rotary units can be fitted with G4, M5 or F7 filters. The units adhere to the current ErP Ecodesign Directive requirements including the stricter, draft 2018 regulations. Furthermore, they help you achieve Passive House approval, thanks to their extremely low SFP values of less than 0.45W per m3/hr. Each model has T2 level insulation, an integrated web server and a sophisticated yet user friendly control system.
