Lunos fans come in a pair and provide continuous heat recovery ventilation without duct work. Includes Rotary Switch. Operated and wired in groups of 2 or 4, these are installed directly in the exterior walls. In operation: one fan exhausts, while the other supplies, then reverse. Available in long (for walls 12-20" deep) or short (for walls 7.5-12" deep).
For projects with walls thinner than 12″ (eg with 2×6 framing), you may want to go with the Lunos e² Short (6.8″) version, which requires a minimum wall thickness of 7.5″. However, the short version comes with a slightly lower efficency (~85%). Otherwise, furring the tube toward the interior is an option for your project to obtain the maximum (90.6%) efficiency in a shorter (ie 2×6) wall assembly.
