About This Product

A heat exchange ventilation system that achieves cleaner air quality with a variety of high-performance filters and air supply and exhaust at 40-second intervals.

■Mechanism of heat exchange

The VLR series is a new heat exchange ventilation system equipped with a wide variety of high-performance filters that can be selected according to the location, surrounding environment, and desired air quality. It has a ductless structure that can be easily attached to the wall, and the built-in high-performance filter shuts out allergens and odors. In heat exchange mode, exhaust/supply air continues to operate alternately at 40 second intervals, resulting in cleaner air and better room temperature. By using ventilation modes according to the season, you can help reduce your annual heating and cooling costs.

■“Heat exchange mode” to maintain room temperature

Basically, an even number of units are installed, and one unit performs the role of air supply while the other unit performs the exhaust role, and the roles change approximately every 40 seconds. Heat is stored in the heat exchange element when exhausting air, and when the air is turned around and outside air is taken in, fresh air passes through the heat exchange element, recovering the stored heat and returning it indoors. The air brought into the room has a smaller temperature difference with the outside temperature, making it more comfortable and helping to reduce heating and cooling costs.

■"Ventilation mode" that takes advantage of outside temperature

An operation mode in which one unit operates continuously for exhaust and the other for air supply without heat exchange. For example, during the summer months when the outside air is cool from night to morning, the system takes in the coolness of the outside air without exchanging heat, helping to reduce heating and cooling costs.

■Uses Earth Plus™️, which is highly antibacterial and safe.

EarthPlus™ is a ceramic composite functional material. It is composed of ingredients approved as food additives and adsorbs and decomposes proteins such as bacteria, viruses, allergens, and odors (recently derived).

■Selectable high-performance filters

High-performance filters that can be selected according to the location of your home, surrounding environment, and desired air quality. In addition to the Earth Plus™ listed on the left, you can also choose from the following. Both have a pleated shape that increases the area by approximately 13 times when expanded, ensuring both durability and large air volume.

■Dedicated hood (4 colors)

The dedicated outside air hood is available in four colors: silver, white, chocolate brown, and black (the deep type is only available in white). Can be selected according to the outer wall or exterior

■Aluminum heat exchange element

Adopts an aluminum heat exchange element with excellent durability and antibacterial properties. Can be washed with water, always clean and can be used for a long time

■Can control up to 8 units

Up to 8 units can be operated with one wall-mounted controller. Two modes can be selected and the air volume can be adjusted in five stages, and it is also equipped with a filter cleaning sign and warning light.
