Mechanical Ventilation Delivering Fresh, Clean Air
With a greater focus on health in our workplaces and homes, the issue of indoor air quality (IAQ) is gaining more attention. Building services professionals play a key role in the design and delivery of systems that support good IAQ. However, provision of good indoor air quality should not simply focus on limiting the risks of illness. With the right systems and good maintenance strategies in place, the indoor environment can support better long-term occupant wellbeing and productivity.
Poor IAQ can lead to a variety of health-related issues and affect the performance of the occupants, whether at work or play. Recent changes to the Building Regulations Approved Documents Part L (energy efficiency) and Part F (ventilation) have been introduced to improve IAQ through the use of energy efficient measures such as mechanical ventilation.
Mitsubishi Electric’s range of mechanical ventilation with heat recovery (MVHR) systems provide the ideal solution for buildings of all shapes and sizes. Here, we take a closer look at our Commercial Lossnay MVHR range.
Widespread Commercial Applications
The average person spends over 90% of their time indoors, be it at work, school, leisure or at home. So, the majority of the air we breathe is the air within buildings. Natural ventilation, such as opening a window, cannot compete with an MVHR system which has been designed to both extract stale, polluted air whilst simultaneously supplying fresh, filtered air.
MVHR systems can be used across an exceptionally wide range of commercial buildings, including offices, retail outlets, restaurants, factories, hotels, leisure facilities and schools. We have produced a range of infographics to help you explain to clients the key aspects of IAQ and why mechanical ventilations systems are so important:
Offices
Offices with the correct level of ventilation are not only nicer places to be in but can improve occupants’ wellbeing, performance and productivity, whilst ensuring a healthy and better- maintained building.
Education
Children and young people are the most at risk from air pollution. Poor IAQ can affect their lung development and have a lifelong impact on their overall health. Delivering plentiful clean air within schools and universities is therefore vital.

Excellent Air Quality and Heat Exchange Efficiency
How our Lossnay MVHR systems work
Our Lossnay systems have perfected the recovery of energy that would have otherwise been wasted. They do this by either warming or cooling incoming air, a feature which makes Mitsubishi Electric MVHR units extremely energy efficient.
Heat Recovery is made possible via the unique Lossnay ultra-thin paper core technology, which is constructed in a corrugated form and layered in alterative directions. This design allows a cross airflow to maximise heat recovery without the supply and exhaust air mixing, ensuring only fresh air is introduced to the building.
Therefore, with Lossnay systems the benefits are twofold: a well ventilated property with clean, fresh air and a reduction in the overall energy required to heat that building.
The Commercial Lossnay Range
Our range includes single and multi-room Mechanical Ventilation with Heat Recovery (MVHR) units, offering medium to large scale ventilation solutions. All systems have been designed to provide the best ventilation solution for the chosen application, by delivering the required amount of fresh air, whilst extracting the right amount of stale air, in the most energy efficient way possible. All of our systems are also compatible with our Mr Slim and City Multi air conditioning systems, creating a complete and highly effective system.
The Mitsubishi Electric Commercial Lossnay range consists of the following systems:
Lossnay LGH-RVX-E
The Lossnay LGH-RVX-E Mechanical Ventilation Heat Recovery (MVHR) systems are designed to supply clean, fresh air into any commercial building, whilst simultaneously extracting stale air, ensuring good indoor air quality for occupant wellbeing.
– Lossnay paper core enables total heat exchange (sensible and latent) to achieve higher levels of heat recovery, resulting in both cost and energy savings
– Low specific fan powers for improved energy efficiency
– Lightweight structure, ideal for ceiling installation
– No condensate drain requirement
Lossnay LGH-RVXT-E
Combining all the features of the RVX model, the RVXT offers a significantly reduced height, whilst maintaining a large airflow. These units are designed for installation in ceiling voids within commercial properties.
– Lossnay paper core enables total heat exchange (sensible and latent) to achieve higher levels of heat recovery, resulting in both cost and energy savings
– Unit height of 500mm for ease of application
– Lightweight structure, ideal for ceiling installation
– No condensate drain requirement
Lossnay LGH-RVS-E
An easy to install commercial ventilation solution suitable for higher humidity applications, the system has been designed with a new set of controls for flexible commissioning. It also comes with optional CO₂ sensors that provide an easy way to control emissions – a requirement following the most recent update to Part F.
– Fresh air ventilation with energy efficient heat recovery
– Plug and play CO₂ sensor control including power
