Vents MICRA 150 Single Room HRV delivers high-efficiency ventilation in a compact, ductless format ideal for spaces up to 1200 sq ft. Engineered with a cutting-edge polystyrene counter-flow core, it recovers up to 88% of sensible heat, reducing energy loss and boosting indoor air quality. Its whisper-quiet operation (as low as 1 Sone), combined with energy-efficient EC fans that draw just 8 to 51 watts, makes it a smart solution for bedrooms, offices, or small living areas. The integrated MERV 7 and MERV 5 filters ensure clean, fresh air while protecting the unit’s internal components. With an intuitive LCD control panel and included remote, the MICRA 150 is simple to use and highly effective.

Casing	Metal polymer coated casing. 3/8" foamed synthetic rubber layer provides heat- and sound-insulation. The modern unit design let it match well with any interior type. The front panel is easily opened for the unit servicing (e.g. for filter cleaning or replacement) and fitted with a protecting opening switch that cuts power supply off if the panel is opened. Air is supplied to the unit and exhausted from the premise through two Ø5" air ducts.
Air filtration	Supply air flow is cleaned with built-in MERV 7 filter, and exhaust flow is cleaned with built-in MERV 5 filter. The filters serve to provide supply of fresh air free of dust and prevent the unit components from soiling.
Air supply and exhaust	High-efficient EC motors with external rotor and forward curved blades are designed for air supply and exhaust. The fan motors have built-in overheating protection and ball bearings for longer service life. Due to EC technologies Micra 150 is featured with low energy demand and reliable operation.
Features condensate drain pan	Some condensate that may be generated during heat recovery process is collected in a special drain pan. As the drain pan is filled with condensate, the unit switches automatically off which is confirmed by indication on the control panel. Remove condensate from the drain pan and restart the unit to continue the unit operation.
Operating logic	The intake air from outside flows through the filter and the heat recovery core and is supplied to the room with the supply centrifugal fan. Warm stale air from the room flows through the filter and the heat exchanger and is exhausted outside through the wall by the exhaust centrifugal fan. In the heat exchanger heat energy of warm extract air from the room is transferred to clean cold air flow from outside. Heat exchange results in minimization of heat losses and lower heating costs. The extract and supply air flows are fully separated, so no contaminations, odors and microbes come to supply air flow.
Heat exchanger	The unit incorporates a high-tech plate counter-flow polystyrene heat recovery core with heat exchange efficiency 85-88%. In winter period the heat exchanger utilizes heat energy of extract air to warm up intake air and decrease the operating load on the heating system. In summer period supply air is cooled down by colder intake air.
Freezing protection	The single-room heat recovery unit MICRA 150 is equipped with a built-in freezing protection. During heat recovery in cold season thermal energy of warm extract energy is transferred to cold intake air. The electronic freeze protection is applied to prevent condensate freezing during cold outside temperatures. If exhaust air temperature at outlet of the core drops down below the set point, the supply fan is stopped. Warm extract air heats the core up and the exhaust air temperature at outlet of the core rises. After that the supply fan is turned on and the unit reverts to the previous operation mode.
Control and operation modes	The unit is equipped with a control panel. The delivery set includes a remote control panel. The control system supports the following 3 operation modes: 1 speed – air capacity 35 CFM; 2 speed – air capacity 53 CFM; 3 speed – air capacity 71 CFM.
