Gemini

Gemini represents the latest generation of decentralised mechanical ventilation with heat recovery. Unlike conventional single-flow units, Gemini uses two independently controlled electronic motors to maintain balanced airflow, creating healthier indoor environments with outstanding energy efficiency. Its engineered technopolymer heat exchanger recovers warmth from outgoing air before introducing fresh filtered air back into the room. Available on selected models with O.Tech smart connectivity, Gemini can automatically respond to indoor air quality, humidity and weather conditions for intelligent, efficient ventilation.

• Balanced simultaneous supply and extract airflow
• Dual electronic motor technology
• High-efficiency engineered technopolymer heat exchanger
• Continuous fresh filtered air
• Reduced condensation and moisture build-up
• Improved indoor air quality
• Quiet, low-energy operation
• Suitable for new-build and retrofit projects
• Optional O.Tech app connectivity with advanced automation

Gemini is available in three models, allowing the system to be matched to the room size and ventilation requirements.

Gemini Mini 100

Designed for installations where wall depth is limited or space is at a premium. The Mini 100 provides balanced heat recovery ventilation in a compact format, making it ideal for smaller rooms, apartments and refurbishment projects.

Gemini Ø100

The standard Ø100 model offers greater airflow capacity while maintaining a compact installation. Ideal for bedrooms, home offices, studies and regularly occupied living spaces.

Gemini Ø160

The highest-capacity model in the Gemini range. Designed for larger rooms and open-plan spaces requiring increased ventilation performance. Compatible with O.Tech smart connectivity on applicable versions.

Depending on the specification selected, Gemini is available with Base, Sensor or O.Tech controls, allowing projects to balance functionality, automation and budget. O.Tech versions include smartphone connectivity, intelligent air quality monitoring, weather-responsive ventilation and automatic operating modes.
