Features and Benefits

  • Vertical installation available for flexibility of application (separate wall mounting kit required – see table below)
  • Lossnay paper core enables total heat exchange (sensible and latent) to achieve higher levels of heat recovery, resulting in both cost and energy savings
  • Flexible supply and exhaust fan commissioning in 5% increments, offering low running costs and easier compliance with Part L. This enables fully customisable fan speed increments (percentage of fan output related to fan speed setting) to suit the application 
  • Optional Mitsubishi Electric energy saving CO2 sensors allow automatic incremental fan control for a healthy indoor environment; sensors powered by Lossnay unit
  • Full airflow in bypass mode, promoting good indoor air quality during free cooling
  • Dual-Barrier coating on the fan prevents dust and grease accumulation, ensuring long-term efficient operation
  • Lightweight structure ideal for easy ceiling installation
  • Control compatibility with Mr Slim and City Multi air conditioning systems for a complete and highly effective system operation


Our Lossnay LGH-RVX(3)-E range can be flipped up-side down to allow greater flexibility when designing duct runs. The enthalpy heat exchanger does not require
a condensate drain or tray, because the moisture passes through the heat exchanger alongside the heat energy
