Thanks to a counterflow enthalpy heat exchanger with heat recovery efficiency of up to 91%, it improves indoor comfort while reducing energy losses, without the need for a dedicated condensate drain. It is suitable for both new construction and renovation projects, offering maximum architectural and system flexibility.  <\/p>\n<h4><span dir=\"auto\">ENTHALPIC HEAT RECOVERY: HEAT AND MOISTURE RECOVERY WITHOUT THE NEED FOR CONDENSATE DRAINAGE<\/span><\/h4>\n<p><span dir=\"auto\">At the heart of the DUO family is <\/span><strong><span dir=\"auto\">a counterflow enthalpy heat exchanger<\/span><\/strong><span dir=\"auto\"> , with an efficiency of up to <\/span><strong><span dir=\"auto\">91%<\/span><\/strong><span dir=\"auto\"> . In addition to recovering energy from the exhaust air, the enthalpy heat exchanger also helps manage humidity more effectively. Thanks to this technology <\/span><strong><span dir=\"auto\">, no additional drain hole is required for condensate drainage<\/span><\/strong><span dir=\"auto\">, which simplifies both installation and architectural integration.<\/span><\/p>\n<p><span dir=\"auto\">Each unit handles up to <\/span><strong><span dir=\"auto\">50 m\u00b3\/h<\/span><\/strong><span dir=\"auto\"> of airflow, recovering energy from the stale air extracted from the room and transferring it to the incoming fresh air before it is directed into the interior spaces. The result is more stable comfort, lower heat loss, and improved energy efficiency.<\/span><\/p>\n<h4><span dir=\"auto\">CLEANER, HEALTHIER, AND BETTER-FILTERED AIR<\/span><\/h4>\n<p><span dir=\"auto\">DUO does more than just ventilate: it actively improves indoor air quality. The filtration system protects the interior from outdoor pollution and also treats the exhaust air, while <\/span><strong><span dir=\"auto\">the ionizer<\/span><\/strong><span dir=\"auto\"> helps reduce dust, pollen, allergens, and unpleasant odors, creating a healthier and more pleasant indoor environment.<\/span><\/p>\n<p><span dir=\"auto\">The humidity control feature can, if necessary, <\/span><strong><span dir=\"auto\">automatically increase<\/span><\/strong><span dir=\"auto\"> , while the nighttime quiet mode reduces the noise level while you sleep.<\/span><\/p>\n<h4><span dir=\"auto\">SIMPLE CONTROLS, CONVENIENT BUTTONS<\/span><\/h4>\n<p><span dir=\"auto\">The DUO product family is designed to be easy to use in any situation.

Wall is the simplest version, designed for direct wall mounting. Slide is a recessed version designed to minimize the unit\u2019s visual presence. Edge is a version intended for built-in installation, even in walls with limited thickness, starting at approximately 13 cm.   <a href=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-10-114254.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-40193 size-full\" src=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-10-114254.png\" alt=\"heat recovery unit\" width=\"1145\" height=\"387\"><\/a><\/span><\/p>\n<h4><span dir=\"auto\">COMFORT, LOW NOISE LEVEL, AND INDOOR AIR QUALITY<\/span><\/h4>\n<p><span dir=\"auto\">DUO units are designed to operate at multiple fan speeds and feature automatic nighttime noise reduction.
