Description

Operating and wired in groups of 2 or 4, these fans provide continuous ventilation without the need for
ductwork – installed directly in the exterior wall. The regenerative ceramic core is charged every 70 seconds,
after which the fan reverses and the incoming air absorbs the stored heat on its way in. The e2 units create a very
quiet heat recovery ventilation system with specific fan efficiency that is second to none.

The basic unit is a through wall fan, with a ceramic regenerative heat exchanger behind it. Operating and wired in pairs, these fans provide continuous ventilation together.

Furring the tube toward the interior is an option for your project with a thinner wall assembly.

  • Creating a very quiet heat recovery ventilation system without the need for ducts and balancing, with specific fan efficiency that is second to none. 

* For bathrooms it is recommended to use the Lunos eGO HRV. The intermittent high efficiency exhaust fan will decrease e2 efficiency slightly during the time it is in operation. If the bathroom is located on an exterior wall a pair of e2 can be installed additionally. The same principle can be applied to kitchens within a space greater than 300 square feet.
