Lunos eGO™ HRV: Your Compact, All-in-One Ventilation Solution
The Lunos eGO is a standalone heat recovery ventilation (HRV) unit designed for small, high-moisture rooms such as bathrooms, kitchens, laundry areas, and offices up to ~150 sq ft.
Unlike the Lunos e², which operates in synchronized pairs, the eGO combines supply and exhaust fans into a single unit, delivering continuous, balanced ventilation through one wall sleeve — no ductwork required.
At its core is the next-generation pbD heat exchanger made from a recyclable polymer-based composite. This advanced material improves airflow, reduces unit weight by over 50%, and lowers manufacturing energy use by more than 70%, all while maintaining strong heat recovery performance.
Ideal for projects where paired systems aren't feasible, the eGO offers a simple, efficient, and reliable solution with up to ~86% heat recovery, low energy use, and minimal maintenance.
Two sleeve lengths are available to accommodate different wall depths — simply choose the correct tube size at time of installation.
Operating Principle - Single-Unit (Simultaneous Supply & Exhaust) Uses two fans operating in opposite directions, eliminating the need for a pair of units.
Airflow Rates (CFM) - Heat Recovery Mode: ≈3/6/12 CFM.
Heat Recovery Efficiency (Max.) Up to 92%
Power Consumption (W) - 1.0−4.9 W
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.
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.
Minimum Wall Thickness - 8 inches (200 mm)Required minimum wall depth
Installation Sleeve Length -
Standard Sleeve: 19.7 inches (500 mm) cut to length.
Short Sleeve: 12.5 inches (317 mm) cut to length. Minimum wall depth of 8 inches (200 mm)
Core Technology
Regenerative Heat Exchange Principle:
The eGO ventilator operates using a regenerative heat exchange cycle, built around a pbD polymer‑based composite heat accumulator. This innovative core is made from an environmentally friendly, recyclable polymer, engineered to reduce
production energy by over 70% and unit weight by more than 50% compared to prior core materials — all while maintaining high heat recovery performance.

High-Capacity Ventilation Built for Tough Conditions
The Lunos e2 60 is a powerful, decentralized Heat Recovery Ventilation (HRV) system that takes the best features of the standard Lunos line and turbocharges them. It’s engineered to deliver a continuous supply of fresh, filtered air to your home or commercial space.
The system works in synchronized pairs, using a regenerative ceramic core to reverse the airflow periodically, recovering up to 90% of your indoor heat.
Heat Recovery Efficiency Up to 97% (Maximum)Tested according to EN 13141-8 (Max. instantaneous value).
Heat Recovery (Reference): 83% at 60 m3/h (35 CFM)Efficiency decreases as the air flow rate increases.
Moisture TransferApprox. 20−30% (ERV function)The ceramic core provides some latent (humidity) recovery, especially in winter.
Airflow Rates5 to 60 m3/h (per unit)Continuously adjustable, with declared volume flow up to 60 m3/h (≈35 CFM).
Maximum Airflow≈35 CFM (or 60 m3/h)Corresponds to the maximum specified volume flow.
Power Consumption0.4−3.3 W (per unit)Extremely low power consumption across the operating range.
Specific Fan Power (SPI)As low as 0.09 W/(m3/h)An industry-leading value for energy efficiency.
Wind Pressure StabilityClass S1 (at 20 Pa)Achieves the highest class for stability against wind and back pressure per EN 13141-8.Export to Sheets
