Introducing the Lunos eGO

egoWhen you need to ventilate a single small room, including bathrooms, the Lunos eGO is the solution.  The eGO is an all-in-one room ventilation system with a built-in regenerative heat recovery core.  It operates using the same tried-and-trusted balanced ventilation with heat recovery as the Lunos e², but with the eGO both the supply and exhaust functions are combined in the same compact unit.

This is accomplished by effectively splitting the unit down the middle with separate dedicated smaller fans for the simultaneous supply and exhaust functions.  The exterior and interior grilles are also split, with supply and exhaust functions pointed in opposite directions – preventing short-circuiting and providing proper circulation.

The Lunos eGO is a through-wall dual fan unit, with a split ceramic regenerative heat exchanger. Operating as a single unit system, the dual fans provide continuous ventilation within a space without the need for duct-work and are installed directly in the exterior wall. The fan’s regenerative core is charged by the oscillation of fan direction. During each cycle, fans take turns exhausting indoor air, which charges the regenerative core. Air flow then reverses and incoming air absorbs the stored heat at 85% tested efficiency.

This animated diagram demonstrates how the e² and eGO operate together as a decentralized system:

The basic specifications are:

  • Ventilation rates: 3-12 CFM in heat recovery mode, up to 27 CFM in exhaust mode
  • Sound levels: 16.8db – 24.0dB – 38.1dB and 38.1dB in exhaust mode
  • Heat recovery efficiency: 85% (tested with DIN 308 / DIBt protocol)
  • Humidity recovery: 20%
  • Specific fan efficiency: 0.17 – 0.2 Wh/m3 (0.29 (W/cfm)
  • Filter: G3 (MERV 5) or optional pollen F5 (MERV 9-10)
  • Includes one controller. One ego may be connected per each controller.
  • Installation sleeve included – can be pre-installed in wall before insulating/during construction
  • The only heat recovery ventilation system that can convert to exhaust mode –  without the need for ducts and balancing, with specific fan efficiency that is second to none.

Dimensions:

  • HRV diameter: 150mm ~ 5.9”
  • HRV length: 243mm ~ 9.6”
  • Min. wall thickness: 300mm ~ 11.8”
  • Core bore: 160mm ~ 6.3″

    Can you give me the wattage numbers for the eGo unit at different speeds? I don’t see that listed on the spec sheet. Thanks.

    • John May 28, 2015 at 12:21 pm #

      John – the eGO runs at 0.29 W/cfm. There are a variety of speeds that it can run at, but the most common are 3 cfm in low , 12 cfm in medium, and 27 cfm in exhaust (no heat recovery) mode. We’ll plan on updating the spec sheet to include that.

    I am interested in purchasing the ego but your shipping costs seem pretty high for what is a small unit. I am quite willing to pony up $ 800 with free (or reduced) shipping. As a side note the Euro has declined about 20% against the dollar in the past year. Could you ship buy USPS?

    • John August 17, 2015 at 10:09 am #

      Hugh,

      Thanks for contacting us. We try hard to lower our prices whenever possible, but because products are imported many months in advance, we can’t base sales on day-to-day or even month-to-month currency fluctuations, so much as bulk purchasing. As the volume increases we’re able to pass savings on. Earlier this year we were able to significantly lower the price of the Lunos e2 and hope the same for eGO. Because Lunos systems are small and ductless, they are also substantially more affordable than other systems with comparable heat recovery efficiency. You’ll find other systems similar in size can’t come close in quality. As for shipping, we do not add any additional – we charge customers what it costs us to ship. We are working to open warehouse locations in multiple regions of North America to reduce shipping time and costs, but there are regions that are harder to deliver to than other. Give us a call, and we’ll see what we can do to help based on your location. Thanks again – as new and growing company, we aim to make it as easy as possible for customers to build high performance buildings that last.

    Can the eGo be used in a narrow wall? (Like the short version of the e2). We’re interested in this for our tiny house build. Thanks.

    • Ken August 17, 2015 at 5:57 am #

      Hi Jody,
      Yes, it can be. Set the unit flush with the outside face of the wall and to the extent that it protrudes beyond interior face of wall simply “box-out” with collar or soffit-like finish construction.
      Sincerely,
      Ken

        Hi, appreciate age now but i’m just facing this issue. Did you go for the eGo with the ‘box-out’? if so, how did it work out. I’ve gt about an inch excess. Thanks

    How many square feet will the lunos ego vent cover?
    How many square feet will an ego2 lunos vent cover?
    Thank for a response.

    I assume one can shut the system off in the summer when the windows are open.
    Thank you Jim.

      Hi Jim,

      Each eGO unit can cover about 250 sq ft, and is designed to be placed in a bathroom or another small space closed off from the rest of building. Each e2 pair covers about 750 sq ft, and we recommend using our blog post on sizing Lunos systems to plan your project: http://foursevenfive.wpengine.com/sizing-lunos-e2-through-wall-ventilation-units/

      We’re happy to help choose the system that would work best for you project, if you are able to send us plans with square footages.

      All Lunos units are operated with standard light switches and can be turned off when desired – though the power draw is so low, that many of our customers choose to leave them on all year. Let us know if there’s anything else we can do to help. Thank you.

    If a house has a balanced system using e2 pairs throughout does the eGO disrupt that balance when it’s in exhaust mode (since it’s not part of a pair supplying it with intake air)?

    • Ken March 24, 2016 at 4:51 am #

      Hi Daniel,
      Yes, exhaust only mode will disrupt balance – consequently we generally recommend that the eGO operate in balanced mode. Exhaust mode should be used only intermittently.

  7. del November 22, 2016 at 10:34 pm #

    You have a “how do the switches work” for the e2. What about the eGo? And what switches – if any – are included with each unit? I’m looking at an e2 pair for the (small) house and an eGo for the bathroom; I want it to be “easy” to put the eGo into exhaust mode when showering; otherwise it will likely stay on 24/7 during at least the winter months.

    • Matt Cull November 23, 2016 at 12:34 am #

      Please refer to the blog post “Which Switch is Which?” This article provides switch information for both the LUNOS e² and the LUNOS eGo systems. The two rocker-switch setup is for both systems. Rocker switches are not provided with the kit. For easy switching to exhaust mode with the eGO, use controller dial setting B or C. These settings will allow you to switch to exhaust mode by simply flipping both switches to ON positions.

    What is the maximum width of walls Lunos eGO units can be fitted through, our current project walls are approximately 500mm to 520 thick

    • John October 17, 2017 at 10:17 am #

      Lunos eGO comes with an installation tube that is 500mm (19.7 inches) in length, which is the maximum. If you need to go beyond that, you will need to get an extension tube – fitting it at a point in the wall that is 500mm would be optimum.
