Mitsubishi Lossnay LGH-15RVX3-E – Energy Recovery Ventilation

Product Overview

The Mitsubishi Electric Lossnay LGH-15RVX3-E is a compact, ceiling-mounted energy recovery ventilation system designed to introduce fresh, filtered outdoor air while extracting stale indoor air.

Using advanced heat and moisture recovery technology, Lossnay transfers energy from outgoing air to incoming fresh air, helping to reduce heating and cooling demands while maintaining a comfortable indoor environment.

Ideal for residential applications, offices and smaller commercial spaces, the system provides efficient, controlled ventilation with quiet operation.
