The Ultimate Heat Recovery Ventilation System
The LGH-RVS Lossnay range is perfect for higher humidity environments such as bathrooms, kitchens and laundries as well as commercial applications such as gyms, healthcare centres, schools and offices. Boasting a range of enhanced features including an integrated bypass damper for free cooling, optional CO2 sensor control and easy control interlock with Mr Slim and City Multi systems – it’s the ultimate heat recovery ventilation system for all areas.
Easy Installation
Being lightweight is one of the most important factors for installation. The light chassis of the LGH-RVS Series can provide a huge advantage in terms of cost and safety of installation.
Easy Drain Piping
The unit features one drain pipe terminal for both supply air (SA) and exhaust air (EA). A condensate trap is not required as the LGH-RVS unit features an internal backflow prevention device and an inclined drain pan, which not only helps with installation, but also reduces the risk of mould and odour.
Flexible condensate pipework and a 360° swivel drain pipe connection means installation can be incorporated into building designs with the ability to avoid obstructions and be set out of the way against walls.
Low Noise Operation and Energy Efficiency
Starting from a super quiet 18dB(A)*, the LGH-RVS Series operates with incredibly low noise thanks to a specialised sirocco fan produced by Mitsubishi Electric. This unique fan balances airflow and static pressure to minimise noise levels. The series also incorporates a high-efficiency motor to reduce power consumption.
Optional Parts for Enhanced Operation
Filter Options
Three filter options offer optimum indoor air quality solutions for projects. Ranging from Standard to Advanced High-Efficiency types. All filters are ISO and EN779:2012 certified.
The easy to remove maintenance panel allows for simple access to the filters for maintenance or replacement.

Optional CO2 Sensor
A Mitsubishi Electric CO2 sensor connected directly to the LGH-RVS unit optimises the fan speed according to the levels of CO2 detected, ensuring indoor air quality is maximised and total heat exchange efficiency is improved. There are two sensor options available, a wall mounted type or built-in.

Silencer Ducts

In facilities and applications requiring ultra-quiet operation, the optional silencer duct is the ideal solution. It contains glass wool and attenuates sound power by absorbing airflow and fan noise.
