Airobot V3 ERV heat recovery ventilation unit

V3 ERV description

Airobot V3 ERV is a heat-recovery ventilation unit (HRV) that continuously supplies fresh air throughout the building while recovering heat from the exhaust air. Airobot is a Estonian manufacturer known for local manufacturing, smart self-learning automation and a moisture-recovering enthalpy exchanger. The V3 ERV model is designed specifically for small apartments and studios, where both energy savings and quiet operation matter.

How Airobot V3 ERV works

The unit draws fresh air from outside while simultaneously extracting stale air from the rooms. An enthalpy (ERV) heat exchanger transfers heat from the exhaust air to the incoming fresh air without the two streams mixing. The result is fresh, filtered supply air that in winter arrives at almost room temperature. This significantly reduces heating costs — often 30–50% compared to natural ventilation.

Energy efficiency and indoor climate

Airobot V3 ERV suits objects of up to 80 m² and is designed to deliver the highest possible heat recovery. Supply air is filtered — typically with an F7 or better filter — which stops pollen, dust and fine particles (PM2.5). It is especially valued by allergy sufferers and families with young children. Filtered air keeps indoor CO₂ levels low, reduces moisture in bathrooms and kitchens, and prevents mould.

Control and automation

This means the unit runs only as much as needed — saving electricity and extending filter life.
