Energy recovery unit INSPIRO
The INSPIRO unit is the most efficient mechanical ventilation with heat and moisture recovery. It is designed for indoor use in residential buildings, halls, storage areas, service spaces, or workshops. It can be paired with either a cellulose or a polyethylene exchanger.
Thanks to its high performance, the ERV provides the right amount of fresh air during daily use and when the building is heavily occupied. Energy recovery significantly reduces the building’s operating costs, particularly in winter.
Key features:
- Airflow ranges from 150 m³/h up to 1300 m³/h
- Cross-flow exchanger with heat and moisture recovery
- Moisture recovery efficiency up to 75%
- Heat recovery efficiency up to 84%
- Galvanised steel casing with thermal insulation
- 2 fans with EC motor
- 10-stage fan speed control
- Differential pressure switch indicating F9 filter clogging
- Intuitive SMART controller included
- CO₂ and humidity sensors (Optional)
- Wi-Fi module (Optional)
- Energy class “A”

Galvanised steel casing and the inspection door
The casing is made of galvanised steel and covered with insulation material that improves thermal performance and reduces noise. It includes practical mounting brackets for easy installation and plastic ducts adapted to standard ventilation pipe diameters. The inspection door provides convenient access to filters and the enthalpy heat exchanger.
POLY heat exchanger - polyethylene with graphene layer
The POLY enthalpy exchanger is made of special polyethylene material with a graphene layer. It offers increased durability and can be cleaned with water and pH-neutral detergent.
Both polyethylene and cellulose exchangers offer similar performance in ventilation units.


Smart operation of the ERV system
INSPIRO and INSPIRO POLY energy recovery units are equipped with energy-efficient EC fans with 10 predefined speed levels. A differential pressure switch measures the pressure before and behind the F9 filter, indicating when replacement is needed. You can program a weekly schedule and activate bypass mode for direct air intake, bypassing the exchanger.
Remote ERV control from anywhere
INSPIRO ERVs can be optionally equipped with a Wi-Fi module*, allowing for full control via a smartphone. By pairing it with the Smart Life app, you can manage fan speed, indoor air temperature, and, if additional sensors are installed, CO₂ and humidity data.
*Wi-Fi module sold separately.


Electric duct heater
For optimal performance, we recommend using a single-stage duct heater, especially when outdoor temperatures drop below -9°C. This prevents the heat exchanger from freezing, particularly in winter.
The duct heater warms incoming air, improving energy recovery efficiency and reducing the risk of damage to the MVHR system.
Filter sets for INSPIRO energy recovery units
Ensure effective and hygienic operation of your energy recovery unit with properly selected filters. We offer ready-made sets dedicated to each INSPIRO model – with G3 pre-filters and either EU9 or EU7 fine filters (depending on your needs).
By default, the energy recovery unit is equipped with an F9 filter providing a higher level of protection: ISO ePM1 ≥ 70%. However, our offer also includes the equally reliable F7 filter, delivering ISO ePM1 ≥ 50% protection for less demanding spaces.
