The Need for Ventilation
The Need for Fresh Air
Poor air quality can be attributed to many problems arising in the workplace and in the home. It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness. Providing good ventilation in residential and commercial buildings is to provide conditions under which people can live and work comfortably and safely.

What can be improved by introducing Lossnay? Ventilation with maximised comfort.
In Summer: Air similar to the conditions of the cooled (dehumidified) indoor air is supplied.
The Need for Appropriate Humidity Management
Viruses such as influenza are found to be active and the survival rate is high in low humidity and dry environments.
In general, the survival rate is said to decrease significantly when the relative humidity (RH) is 50% or more when the temperature is 20°C. During the winter, keeping an appropriate humidity and heating temperature can help prevent influenza.

LGH Series
IMPROVED AIR VOLUME RANGE
Wide Range Air Volume
The LGH-RVX/RVXT are equipped with four fan speeds. In addition, each speed has a range setting of 25, 50, 75 and 100%, allowing much finer air volume control.
When used in combination with the CO2 sensor or timer function, the air volume can be controlled according to conditions that produce better performance and reduce power consumption.
LGH-RVX/RVXT Series Model Characteristic Curves
Offers a wide range of airflow variations, from fine to large volume
Air Volume Control by CO2 Sensor
An external CO2 sensor can be connected directly to the Lossnay RVX/RVXT units, allowing the fan speed to vary according to the CO2 levels detected. When the CO2 concentration is low, the unit can operate at a lower air volume compared to previous models and this improves total heat exchange efficiency and contributes to energy saving.

Fan Speed Adjustment Function
The default fan speed value can be adjusted slightly. Use the PZ-61DR-E remote controller to reset the speed.
1. The fan speed will be adjusted automatically after a given period of time to allow for increased filter static.
2. After the unit is installed, if the air volume is slightly lower than the desired airflow, it is possible to make fine adjustments from the unit's dip switches.
IMPROVED INSTALLATION
Connect ducts in two different directions (OA, EA side)
Ducts can be connected in two different directions to the outdoor vents, thanks to collars and aperture plates that can be interchangeably placed in two different positions. This flexibility allows for installations close to the surface of a wall and helps avoid cases where the stale air exhaust vent would be blocked by an obstruction of some kind. This makes both planning and installation that much simpler.

VENTILATION AND AIR CONDITIONING
The OA (Outdoor air) Processing Unit creates an optimum environment while providing substantial energy savings. The OA Processing Unit comprises forced air ventilation, heat recovery, heating and cooling, and air purification. This total air conditioning system keeps indoor air fresh and comfortable all year round, and keeps it free of contaminants. Inside the OA Processing Unit is the Lossnay core, a heat exchange unit that transfers heat efficiently, cutting ventilation load by as much as 70%.
A remarkable product found nowhere else, this special combination of functionality and performance contained within a single unit ensures users ample comfort, good health, and energy savings.
GUF-RD type
OA (Outdoor air) Fresh, outdoor air in a quantity required for ventilation is drawn in by the supply fan.

PERMEABLE FILM HUMIDIFIER (GUF-RDH ONLY)
Comfortable Level of Humidity for Exceptional Air Quality
The OA Processing Unit is equipped with a permeable film humidifier developed by Mitsubishi Electric. Steam transmission efficiency has been improved by lowering the resistance of the material. By providing an optimum level of humidity, the OA Processing Unit creates a comfortable interior environment which may prevent irritations such as dried out eyes or a parched throat that can be caused by insufficiently low levels of humidity in the air.
Highly Efficient Humidification
Improvements in the system of airflow patterns and water injection techniques have resulted in a substantial increase in humidifying volume. The system also controls the humidity level of the air that is exhausted, ensuring an efficient, environmentally friendly manner of operation.
Note: In the case in which the level of residual impurities exceeds 100mg/ please use a water purifier.
DUAL-FAN SYSTEM
Reliable Ventilation
The OA Processing Unit utilises a dual-fan configuration for the intake and exhaust of air from a building. A forced air method is incorporated for the simultaneous supply and exhaust of air to support effective ventilation even in highly insulated airtight rooms. The Lossnay core is designed in such a way that the passages for air being drawn into and exhausted from a building are entirely separate. This setup prevents the mixing of indoor and outdoor air for safe, reliable ventilation.
FREE COOLING
When the air conditioning system is operating in its cooling mode and the temperature of the air outdoors drops below the temperature indoors (e.g. a summer night), the OA Processing Unit detects this and automatically switches to a mode of operation which bypasses the heat recovery unit. Bringing in cool air from outside serves to help reduce the air conditioner's cooling load.
HEAT PROCESSING
A direct expansion heat exchanger is incorporated to compensate for any heat loss that may occur during ventilation. It also improves the efficiency of humidification in the winter.
VARIABLE DUCT POSITIONS
The connection position of the outside duct is variable allowing for more complicated duct installations.
Standard installation
A space is necessary to prevent the influx of rainwater.
Installation with duct direction changed
Can be installed close to the surface of the wall.
Avoid installations where the stale air exhaust aperture would be blocked by lighting or air conditioning units.

Each main fan speed value can be further adjusted slightly. Use the PZ-61DR-E remote controller to adjust the speed.
1. Considering the total hours of Lossnay operation (filter clogging), the fan power can be adjusted automatically after a given period of time.
2. After the unit is installed, if the air volume is slightly lower or higher than the desired airflow, it is possible to make fine adjustments. (Fan speed 4 is available only 1down and 2down)
