How many Lunos do I need?
Lunos e2 operates in pairs, each pair providing up to 22 CFM ventilation. Check out this page to see how you can size your own Lunos system. If you want, we are happy to take a look and support.
I am building a tiny house. Is Lunos the right system for me?
Yes. Lunos is a popular solution for small homes and tiny houses, as it lets you have a balanced supply of fresh air without any ductwork typically associated with a ventilation system. This means you get whole house ventilation just through 2 holes in your wall. The blog posts below delve deeper into the Lunos through-wall HRV system.
How many fans can I connect to a Lunos controller?
You can connect groups of 2 or 4 Lunos e2 fans to one controller. You can see a video showing installation here. A guide to installing and operating the Lunos system can be found on the product page.
Do I need to buy a controller/transformer/anything else with my Lunos?
A Lunos e2 box, in addition to the fan unit, comes with a transformer and a universal controller. You will need to get rocker switches, switch plate, electrical box and low voltage wire.
Can I get Lunos in Canada?
No. We are sorry, but 475 is exclusive distributors for Lunos only in the USA. We cannot sell or distribute any Lunos products to Canadian customers.
Can I install the Lunos through my roof?
No, you cannot install fans in your roof/ceiling. Lunos units can only be installed through the wall assembly horizontally.
How long is the Lunos system? Will it work with my wall thickness?
The minimum wall thickness for the Lunos e2 standard version is 12” or 300 mm and for the Lunos e2 short version is 7.5”. The tube you will receive with your order is 20” long and you can cut it to the size you require. If the wall thickness is less than minimum tube length, you can keep the extra length to the inside of the building envelope and box out your wall inward.
