FRESIA Sense ERVQ-B150-1B1(H02) – wall-mounted ERV with G3+F5+HEPA H10 filtration and CO2 control, 150 m³/h

Product detailed description

The FRESIA Sense ERVQ-B150-1B1(H02) is a ductless energy recovery ventilator that hangs on the external wall of a room. It supplies filtered outdoor air and extracts used indoor air at the same time. Inside, an enthalpy exchanger with a membrane transfers heat and part of the moisture between the two airstreams, reaching a thermal efficiency of up to 82 %.

The incoming air passes through a chain of four filters: G3, F5, HEPA H10 (declared efficiency 99 %) and an activated-carbon filter. The unit is therefore a sensible option where outdoor air quality matters and a ventilation system cannot be added in any other way.

The H02 version has a built-in CO2 sensor and a display showing CO2 concentration, temperature and relative humidity. In automatic mode the output follows the CO2 level, so the fan runs faster only when it is needed. Eight speeds, high-efficiency DC fans, a maximum airflow of 150 m³/h and a power input of 35 W are paired with noise of 22.6–37.9 dB(A) depending on the speed. Labelled sound power is 39 dB; energy class A (EPREL 2708346, Regulation 1254/2014).

FAQ

Does the unit need ductwork inside the building?
No. It is a ductless system – only two openings in the external wall are required.

What does the CO2 sensor do?
It measures the CO2 level in the room and, in Auto mode, raises or lowers the fan output accordingly.

Can one unit ventilate a whole home?
It is designed for a single room or zone. For a larger home, the number of units should be planned according to floor area, occupancy and the required air exchange.
