Lunos eGO™ HRV: Your Compact, All-in-One Ventilation Solution

The Lunos ego™ is an ultra-compact, ductless heat recovery ventilation (HRV) system, uniquely engineered for optimum air quality in small or single-room spaces such as bathrooms, kitchens, WCs, or rooms up to approximately 150 sq. ft.

Unlike the paired operation of the Lunos e2 system, the ego unit contains two fans in a single device, allowing it to simultaneously supply fresh air and exhaust stale air, all while utilizing a regenerative ceramic core to recover heat.

Operating Principle Single-Unit (Simultaneous Supply & Exhaust) Uses two fans operating in opposite directions, eliminating the need for a pair of units. Primarily for wet rooms (bathrooms, kitchens).

Airflow Rates (CFM)- Heat Recovery Mode: ≈3/6/12 CFM. Corresponds to ≈5/10/20 m3/h

Airflow Rates (m3/h)- Heat Recovery Mode:5/10/20 m3/h Corresponds to ≈3/6/12 CFM

Exhaust Boost Mode (CFM) Up to ≈27 CFM Corresponds to 45 m3/h (For quick moisture/odor dissipation)

Exhaust Boost Mode (m3/h) 45 m3/h

Heat Recovery Efficiency (Max.) Up to 85% to 92%- Depends on the specific model and testing protocol (e.g., 85% tested with DIN 308 / DIBt protocol). Newer units with pbD heat exchanger may reach up to 92%.

Heat Supply Level to EN 13141-8 - 75% to 91%Varies based on model and reference volume flow. An older spec cites 75%, a newer one cites up to 91%.

Moisture Transfer (ERV) 20%−30%The regenerative core provides some humidity recovery.

Power Consumption (W)- 1.0−4.9 W per unit. Low power usage across operating modes.

Specific Fan Efficiency (SFE)- 0.29 W/cfm. Also specified as 0.17/0.2 Wh/m3.

Minimum Noise Level- As low as ≈16.8 dB (Sound pressure level)Range is generally 16.8 dB to 24.0 dB in heat recovery mode. Exhaust mode is louder, up to 38.1 dB.

Energy Efficiency Class- A (or A+) Achieves Energy Efficiency Class A according to the Ecodesign Directive (some variations are A+).

Filter Class- G3 (MERV 5)Regenerable replacement filters are standard. Pollen (MERV 9-10) filters are optional.

Unit Diameter- Approximately 6.1 inches (154 mm) for the fan unit. This is the diameter of the fan and heat recovery core that slides into the sleeve.

Core Bore Size- 6.3 inches (160-162 mm). This is the required diameter for the hole drilled through the wall to fit the sleeve.

Installation Sleeve Length -

Standard Sleeve:19.7 inches (500 mm) cut to length. Suitable for a range of wall thicknesses, generally up to 19.7 inches.

Short Sleeve- 12.5 inches (317 mm) cut to length. Suitable for wall depths from 8 inches (200 mm) to 12.5 inches (317 mm).

Minimum Wall Thickness

Standard Fan: 12 inches (300 mm)Required minimum wall depth for the Standard Fan/Sleeve option.

Short Fan: 8 inches (200 mm)Required minimum wall depth for the Short Fan/Sleeve option.

Installation Type: Through-wall (Ductless)The unit is a decentralized Heat Recovery Ventilator (HRV) that installs directly into an exterior wall.

Core Technology

Regenerative Heat Exchange Principle: The system operates on the principle of regenerative heat exchange, similar to the Lunos e² units.

It uses a ceramic core (acuvent storage stone) with a honeycomb structure to store thermal energy.

During one part of the cycle, exhaust air transfers its heat to the ceramic core.

During the reverse cycle, incoming fresh air absorbs the stored heat from the core.

High Heat Recovery Efficiency: The system is highly energy-efficient, with tested heat recovery efficiencies of 81.4% to over 86% (depending on the fan length/model).

Low Power Consumption: It features very low power consumption, starting from as low as 1.0 W (watt).

Quiet Operation: It is designed for quiet operation, with sound levels ranging from about 16.8 dB to 24.0 dB in heat recovery mode.

Compact Size: The eGO is noted for its small dimensions, positioning it as one of the world's smallest decentralized fans with heat recovery in the two-channel device class.
