Thermal and acoustic insulation is provided by a 10-mm-thick layer of synthetic rubber. <\/p>\n<p>The front panel provides convenient access for filter maintenance and features a lock for added security.<\/p>\n<p>The unit has two 100 mm pipes for drawing in fresh air and exhausting stale air. A third 100 mm pipe (included in the delivery) can be installed on the unit to connect to the air duct leading out of the bathroom. <\/p>\n<h3>Engines<\/h3>\n<p>The units are equipped with high-efficiency electronically commutated (EC) motors featuring an external rotor and impellers with forward-curved blades. These state-of-the-art motors represent the most advanced solution in the field of energy efficiency today. <\/p>\n<p>EC motors are characterized by high performance and optimal control across the entire speed range. In addition, the efficiency of electronically commutated motors reaches impressive levels, up to 90%. <\/p>\n<h3>Air valves<\/h3>\n<p>The unit is equipped with supply and exhaust air dampers that activate automatically to prevent drafts when the unit is turned off.<\/p>\n<p><strong>Air Filtration<\/strong><\/p>\n<p><strong>Freshbox 100 WiFi, Freshbox E-100 WiFi: <\/strong>G4 and F8 filters are used to purify <strong>the incoming air <\/strong>. To meet stricter air purity requirements, the F8 filter can be replaced with an H13 or F8 carbon filter (sold separately). The exhaust air is purified by a G4 filter.  <\/p>\n<p><strong>Freshbox E1-100 WiFi, Freshbox E2-100 WiFi: <\/strong>The <strong>built-in <\/strong>G4 supply air filter and G4 exhaust air filter ensure air filtration.<\/p>\n<h3>How It Works<\/h3>\n<p><strong>Cold outdoor air passes through <\/strong>the filters and the heat exchanger, and is then delivered to the space being serviced by a centrifugal supply fan.<\/p>\n<p><strong>Warm, contaminated air from the room flows <\/strong>through a filter and a heat exchanger, and is then expelled by a centrifugal fan through an air duct in the wall.<\/p>\n<p><strong>The supply and exhaust air flows <\/strong>are completely separated, which helps prevent the spread of odors or microbes between them.<\/p>\n<h3>Heat and Energy Recovery<\/h3>\n<p>Freshbox <strong>100 WiFi units <\/strong>are equipped with a counterflow heat recovery core featuring a polystyrene core.<\/p>\n<ul>\n<li><strong>During the cold season <\/strong>, heat <strong>is recovered <\/strong>from the exhaust air<\/li>\n<\/ul>\n<p>It is sealed and the supply air flow is directed through it, which reduces heat loss due to ventilation.<\/p>\n<p>Condensate may form during heat recovery. The condensate collects in the drain pan and is removed through the exhaust air duct. <\/p>\n<ul>\n<li><strong>During the warm season <\/strong>, heat from the supply air <strong>is transferred <\/strong>to the exhaust airflow.<\/li>\n<\/ul>\n<p>This allows the supply air temperature to<\/p>\n<p>significantly reduce, which in turn reduces the load on the air conditioner.<\/p>\n<p>Freshbox <strong>100 ERV WiFi devices <\/strong>are equipped with<\/p>\n<p>with a counterflow energy recovery core, the core of which contains an enthalpy membrane<\/p>\n<p>&nbsp;<\/p>\n<p><strong>PREHEATING<\/strong><\/p>\n<p><strong>The Freshbox E-100 WiFi and Freshbox E2-100 WiFi units <\/strong>are equipped with an electric preheater to prevent the heat exchanger from freezing.<\/p>\n<p><strong>FOLLOW-UP<\/strong><\/p>\n<p><strong>The Freshbox E1-100 WiFi and Freshbox E2-100 WiFi units <\/strong>are equipped with an electric reheating device that raises the supply air temperature when necessary.<\/p>\n<h3>Freeze Protection<\/h3>\n<p><strong>The Freshbox 100 WiFi has <\/strong>an exhaust air temperature sensor located after the heat exchanger, which turns off the supply fan so that the warm exhaust air can heat the heat exchanger. After that, the supply fan turns on and the unit returns to normal operation. <\/p>\n<p><strong>The Freshbox E-100 WiFi and <\/strong> <strong>Freshbox E2-100 WiFi <\/strong>feature <strong>overheating protection <\/strong>provided by a preheater.<\/p>\n<h3>(Vents Micra 100 Wi-Fi)<\/h3>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<h3>Blauberg Freshbox 100WiFi Heat Recovery Unit, 100 m\u00b3\/h<\/h3>\n<ul>\n<li><span dir=\"auto\">Heat recovery efficiency: 96%<\/span><\/li>\n<li><span dir=\"auto\">Heat exchanger type: Counterflow<\/span><\/li>\n<li><span dir=\"auto\">Sound-insulated housing<\/span><\/li>\n<li><span dir=\"auto\">Motor type: EC<\/span><\/li>\n<li><span dir=\"auto\">Last Week: Automatic<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":41995,"template":"","meta":{"_acf_changed":false,"_seopress_titles_title":"Series Blauberg Freshbox 100WiFi Heat Recovery Unit","_seopress_titles_desc":"Blauberg Freshbox 100WiFi Heat Recovery Ventilator, 100 m\u00b3\/h.
