Its rectangular structure allows for a larger heat transfer surface area while maintaining the same dimensions, helping to improve overall heat recovery efficiency.<\/span><\/p>\n<p><span dir=\"auto\">In addition, stainless steel ensures greater mechanical strength, better resistance to corrosion and pollutants, longer durability, and more stable performance over time. This technical choice makes Kers Premium particularly well-suited for those seeking an advanced decentralized ventilation system without sacrificing ease of installation and everyday convenience. <\/span><\/p>\n<p><a href=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095636.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-40204 size-full\" src=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095636.png\" alt=\"Kers Premium\" width=\"772\" height=\"863\"><\/a><\/p>\n<p><a href=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095537.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-40205 size-large\" src=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095537-1024x352.png\" alt=\"Kers Premium\" width=\"1024\" height=\"352\"><\/a><\/p>\n<p><a href=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095705.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-40203 size-large\" src=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095705-1024x684.png\" alt=\"Kers Premium\" width=\"1024\" height=\"684\"><\/a><\/p>\n<p><a href=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095749.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-40202 size-large\" src=\"http:\/\/proair.ee\/wp-content\/uploads\/2026\/04\/Kuvatommis-2026-04-13-095749-1024x672.png\" alt=\"Kers Premium\" width=\"1024\" height=\"672\"><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<h3>Kers Premium 25 Heat Recovery Unit with Stainless Steel Heat Exchanger and A+ Ionizer, 25 m\u00b3\/h<\/h3>\n<ul>\n<li>Provides fresh air from outside the building, with an airflow rate of up to 100 m\u00b3\/h<\/li>\n<li>Recover up to 97% of the heat from exhaust air to heat incoming air in the winter and cool it before it enters the room in the summer.<\/li>\n<li>It filters both the incoming outdoor air and the exhaust indoor air thanks to the G3 filters on both sides.<\/li>\n<li>Purify the air with the negative-ion ionizer, which is always active when the Kers Premium is turned on.<\/li>\n<li>Reduce unwanted outside air infiltration with an automatic damper<\/li>\n<li>These units are designed for residential and commercial buildings, particularly in locations where centralized ventilation systems are not considered necessary.
