FEATURES  
  • Efficient supply and exhaust ventilation of separate premises (rooms).
  • Enthalpy cross-flow heat exchanger with heat recovery efficiency from 68 % up to 77 %.
  • Centrifugal fans with forward curved blades.
  • Asynchronous motors with ball bearings. Integrated control system with three operation modes and air flow range from 40 up to 80 m³/h.
  • Silent operation (24/32/41 dBA).
  • Air filtration with two integrated G4 filters.
  • Easy installation.
  • Suitable for continuous operation.
OPERATING LOGIC  
  • Fresh intake air from outside moves through the filter and the heat exchanger and is delivered to the premise with the supply fan.
  • Warm stale air moves from the room through the filter and the heat exchanger and then is exhausted outside with the exhaust fan.
  • Heat energy of warm extract air is transferred to clean intake air and warms it up.
  • Heat recovery minimizes thermal energy losses and space heating expenses in cold seasons.
  • Intake and extract air flows are fully separated within the heat exchangers and pollutants, odours and microbes contained in extract air are not transmitted to supply air.
CONTROL AND AUTOMATION  
  • The unit is operated with a three-position speed switch.
  • The control system enables three operation modes:
  1. Supply and exhaust ventilation with minimum air flow rate of 40 m³/h and noise level of 24 dBA.
  2. Supply and exhaust ventilation with medium air flow rate of 60 m³/h and noise level of 32 dBA.
  3. Supply and exhaust ventilation with maximum air flow rate of 80 m³/h and noise level of 41 dBA.
А3: three-position speed switch (P3-1-300)

Ventilation system arrangement
Ventilation system arrangement
  • One MICRA 80 A3 air handling unit should be installed in each space requiring ventilation.
  • A single unit is capable of ensuring efficient ventilation in spaces with floor area up to 32 m².
  • A ventilation system based on MICRA 80 A3 is able to provide continuous air exchange and save heat in winter and cool in summer.
  • Mark the holes for the air ducts on the wall with the supplied cardboard master plate. After drilling the holes fix the master plate to the wall with a mounting tape. Insert the 125 mm plastic air ducts in the core holes.
  • The master plate is used to place the air ducts in a required position and to align the unit spigots with the air ducts.
  • Install the outdoor ventilation hoods from outside to prevent ingress of water and foreign objects inside the unit.
  • Install the air ducts slightly sloped down to outside to ensure condensate drainage from the unit.
  • After the air ducts are fixed in required position using the outer ventilation hoods and the master plate fill the gaps between the air ducts and the wall with a mounting foam through the special slots in the master plate.
  • After the mounting foam hardens, remove the master plate and cut protruding parts of the air ducts to be flush with wall surface.
  • To mount the unit casing, open the service panel and take off the heat exchanger.
  • Connect the unit spigots to the plastic air ducts and fix the unit casing to the wall with screws and dowels.
  • After completion of the casing mounting and wiring operations re-install the heat exchanger and the front panel.
