Wall-mounted Heat recovery unit Mitsubishi Electric Lossnay VL-80U5-E (pull-switch)

Description

Mitsubishi Electric Lossnay VL-80U5-E is a single-room ventilation unit with heat recovery. It delivers fresh air in and extracts stale air simultaneously through the Lossnay heat-exchange core, reducing heat loss and improving indoor air quality. This model features a pull-cord control for quick mode changes, quiet operation, and low power draw. This device is ideal for apartments, houses, home offices and small classrooms where ductwork is not feasible. 

Key differences at a glance

• Pull-cord control with three positions: HI (Fast), LO (Slow) and OFF
• Airflow up to 80 m³/h (HI) and 49 m³/h (LO).
• Low sound: ~26 dB (LO) / ~37 dB (HI).
• Heat-exchange efficiency: ~70 % (LO) / ~62 % (HI).
• Dual filtration with optional high-performance outdoor filter (P-80HF-E) to reduce insect ingress; standard replacement filter P-80F-E.

What does a heat recovery unit solve?

In rooms with inadequate ventilation, typical issues arise:

1. Moisture build-up and window condensation;
2. Mold and mildew formation, allergy risks;
3. Elevated CO₂ that harms well-being and focus;
4. Damage to finishes, furnishings and electronics.

The Lossnay VL-80U5-E:

1. Provides continuous air exchange without opening windows;
2. Uses a heat-exchange core to temper incoming air using indoor air energy;
3. Reduces particles with integrated filters for supply and extract air;
4. Improves comfort, health and productivity for occupants.

Where to use this device?

Perfect for:

• Apartments and private homes;
• Home offices, studios and small workspaces;
• Educational rooms and small meeting rooms without central ventilation.

Note: For bedrooms, install at a distance to avoid perceiving airflow/noise in very quiet environments.

Features of Mitsubishi Electric Lossnay VL-80U5-E

• Pull-cord operation: quick switching between HI/LO/OFF; vertical or horizontal airflow can be adjusted via manual louver; do not pull the cord at an angle.
• Energy efficient heat recovery for tightly sealed homes; low running watts.
• Quiet running suitable for living spaces; wall-mount only (not for ceiling mount).
• Weather covers (included) must be used in adverse conditions; stop operation below -10 °C and fit covers to prevent ingress of rain/snow and protect the core. 

Installation

This unit is designed for wall installation with an outdoor weather hood. Keep clearances around the unit to avoid blocking inlets/outlets and to allow service access. Installation should be performed by authorized personnel.

Maintenance & filters

• Clean outdoor and exhaust filters at least every 6 months; replace standard filter P-80F-E after ~4 washes.
• Optional P-80HF-E outdoor filter reduces small insects; clean with vacuum, do not use hot water or harsh detergents.
• Clean the Lossnay core annually with a vacuum only (no water/chemicals).
