The Lossnay LGH-RVXT3-E is designed to supply clean, fresh air into commercial buildings, whilst simultaneously extracting stale air. These units offer a significantly reduced height and also maintain a large airflow, allowing easy installation in ceiling voids. These units can also recover valuable heat and latent energy from inside the building, maximising energy efficiency and reducing running costs.

Available in: 160, 200, 250

Optimised Space Usage_rvxt3

Optimised Space Usage

The LGH-RVXT3 series stands out with its unique ability to provide a solution for narrow ceiling spaces while ensuring a spacious indoor environment. Its slim profile allows for effective space utilisation without compromising performance, optimising room space.

Enhanced Static Pressure_rvxt3

Enhanced Static Pressure

The RVXT3 series provides higher external static pressure than previous models, with equal external static pressures for SA and EA. This simplifies the design of ventilation systems, allowing for more significant pressure drops in ductwork.

Adaptable Installation_rvxt3

Adaptable Installation

DIP switches can be set to change airflow direction, allowing for adaptable ductwork and sufficient maintenance space. The indoor (SA/RA) and outdoor (OA/EA) sides can be switched depending on installation requirements. However, the unit cannot be installed upside down.

Comfort and Energy Efficiency_lgh

Comfort and Energy Efficiency

The optional CO2 sensor controls airflow in 16 steps according to the room's CO2 levels, preventing over-ventilation while maintaining high indoor air quality. This feature helps reduce the air-conditioning load by optimising ventilation output. The CO2 concentration can be monitored in real-time on the remote controller (PZ-62DR-EA/EB) or via LED indicators on wall-mounted sensors, with wall-mounted and duct-mounted sensors options.

Centralised Air Distribution_rvxt3

Centralised Air Distribution

Multiple LOSSNAY units can be operated as a single system, with up to four units connected. Four LGH-250RVXT3-E units combined deliver a total air volume of approximately 2778 l/s, depending on system design and site conditions*. * Only identical models can be grouped together, and synchronised control requires connection to the PZ-62DR-EA/EB. Up to four LOSSNAY units can be connected in one group, consisting of one leader unit and three follower units.

Stable Airflow with Constant Pressure Control

Stable Airflow with Constant Pressure Control

By integrating a field-supplied pressure sensor, LOSSNAY adjusts airflow based on the pressure level in the duct or distribution chamber. When a higher-pressure level is detected, airflow is reduced automatically, ensuring stable airflow in each room.

Simultaneous air supply and exhaust_LGH

Simultaneous air supply and exhaust

Lossnay is the ultimate ventilation system that provides fresh clean air from outside, while removing both moisture and stale indoor air at the same time. Bringing fresh air into the occupied space can help improve indoor air quality by removing indoor pollutants including CO2, ozone, VOC’s, etc.

Heat recovery ventilation_LGH

Heat recovery ventilation

Heat is recovered from the outgoing stale air. This heat is utilised to pre-heat incoming fresh air so your air conditioning system is not required to work as hard to maintain desired room temperature.

Use with Mr Slim & City Multi Systems

Use with Mr Slim & City Multi Systems

Lossnay can be integrated and interlocked with a Mitsubishi Electric Mr. Slim and City Multi air conditioning systems. The ducted system provides heating and cooling while the Lossnay ventilator brings in fresh air into the home while expelling the stale air at the same time.
The heat recovery operation can help reduce the load on the ducted air conditioning system.

Standard G4 Filter (Supplied)

Standard G4 Filter (Supplied)

The improved standard filter cuts pollen and dust for fresh, clean air. They can be washed for easy maintenance. Replacement filter is available as optional part no. PZ-**RF3-E. (Coarse 60% (ISO 16890: 2016).

Advanced high efficiency filters (Optional)

Advanced high efficiency filters (Optional)

The supply and exhaust air filters can be upgraded to grade M6 and F8, respectively for improved indoor air quality by removing finer particles, pollen, bacteria and dusts. These optional filters are disposable type (non-washable).

Mitsubishi Electric Ventilator Selection Tool

Mitsubishi Electric Ventilator Selection Tool

The Mitsubishi Electric Ventilator Selection Tool allows installers to prepare energy savings calculations comparing a conventional ventilation system to a Lossnay unit. The calculations include annual power consumption (kWH), CO2 emissions (kg) and energy savings ($) for a specific location. The tool also generates Technical Data, including acoustic information.

PZ-62DR-EA/EB wired 7 day controller (Optional)

PZ-62DR-EA/EB wired 7 day controller (Optional)

Backlit LCD Lossnay remote controller provides ON/OFF control, fan speed adjustment, weekly timer, as well as advanced functions such as night-purge, by-pass ventilation and CO2 level display.

Night Purge (Requires PZ-62DR-EA/EB controller)

Night Purge (Requires PZ-62DR-EA/EB controller)

During the summer season, the Night Purge mode draws cooler outside air into the room at night. This energy conservation mode reduces the load when the air conditioning is started up the next morning. With new models, it is possible to manually engage and set the night purge operation.

Bypass Ventilation Mode_LGH

Bypass Ventilation Mode

When the outdoor temperature is close to the indoor temperature, the Lossnay unit can be set to run in by-pass ventilation mode to open the built-in damper inside the unit to exhaust the stale room air straight to outside without going through the heat exchanger.

CO2 sensor (Optional)_LGH

CO2 sensor (Optional)

Mitsubishi Electric can provide option CO2 sensor that can be connected directly to a LOSSNAY RVX3 unit to automatically adjust the fan speed according to the indoor CO2 level. This contributes to further energy savings.
Two types of CO2 sensors are available: wall-mounted (PZ-70CSW-E) and duct-mounted (PZ-70CSD-E) types.

Dual Barrier Coating_LGH

Dual Barrier Coating

Dual Barrier Coating reduces dust and greasy dirt from collecting on the surfaces of the Air Supply Exhaust fan and airborne contaminants sticking to the unit, providing a ventilator that is not only cleaner but also requires less cleaning.
