The slimline, vertical VL500 Lossnay Fresh Air Heat Recovery Ventilation System provides the ultimate in energy efficient ventilation to ensure your home has a constant supply of healthy, fresh air.

Air volume: 139l/s (Fan Speed 4). (WxDxH, mm) 725 x 556 x 632. Weight: 39kg. Duct size: 157mm. Operated by the simple to use backlit LCD controller located on the right side with Automatic Summer Bypass.

Designed for Flexibility and Convenience

The Vertical Lossnay Range is designed specifically for the New Zealand housing market and makes energy efficient, super-quiet ventilation accessible to even more homes.

Vertical Lossnay Units, VL250, 350 and 500

Because of the slimline, vertical upright design, the Lossnay Ventilation System is not limited to an in-roof installation. With its small upright footprint it can be placed in the garage or a cupboard in the kitchen. Now whole home ventilation can be installed without compromising the architectural design of the building.

Automatic Summer Bypass

Using the on-board temperature sensors, the Vertical Lossnay unit automatically enters Bypass Mode when it detects a space is hotter than desired and the outside air is cooler.

To reduce the risk of overheating the home, fresh air is introduced, bypassing the Lossnay Core. This is ideal for cooling down a dwelling that may have overheated during the day once the outside temperature has dropped in the evening.

Easy to Use Control

A built-in LCD controller allows for easy control and commissioning of the unit. This interface displays all functionality and temperature settings of the system.

Slimline to Fit in a Cupboard

The vertical upright design of the Lossnay Ventilation System is not limited to an in-roof installation. Now whole home ventilation can be integrated into the overall building design without limitations.
